Measurement and Application of Seat Whiplash Backrest Opening Angle Based on Video Recognition Technology LIU Fandong, GUAN Yongxue, LI Shifeng, XIE Jinping, XU Li, ZHANG Xinhua 2026, 51(5): 29-34.  DOI: 10.16638/j.cnki.1671-7988.2026.005.006 Abstract ( )   PDF (1131KB) ( )   The traditional contact measurement of the dynamic tension angle of the seat back in the car whiplash test has problems such as installation limitations and interference with the test response. This paper proposes a non-contact measurement method based on video recognition, using Python+ OpenCV as the technology stack. It adopts the channel and spatial reliability tracker (CSRT) algorithm to track the backrest feature marker points in high-speed video and calculates the angle between the two-point connection vector and the horizontal axis through spatial coordinates. When calculating, first obtain the pixel coordinates of the marked points and complete the planar coordinate conversion. Then, apply inverse trigonometric functions (such as atan2) to solve the angle between them and the horizontal reference, achieving frame-by-frame quantization of the tension angle. The whiplash test results of a certain model of Jiangling show that the Pearson correlation coefficient between this method and the measurement results of Falcon software (whose measurement algorithm adopts the contour fitting method, using the least squares method to fit straight lines and arcs) reaches 0.998 (extremely strong correlation), and the average relative error is 5.27%. Error analysis shows that its accuracy is particularly outstanding in the medium and high tension angle range (>3°) (with an average relative error of <5%), meeting the accuracy requirements for dynamic tension angle measurement of seat backrests stipulated in the China new car assessment programme (C-NCAP) management regulations (2024 Edition) regulation, and it also has the advantages of flexible operation and no contact interference.

Based on the modal stress recovery method, using the virtual proving ground (VPG) technology to obtain the modal coordinates of the vehicle body at each stage as the input, the fatigue software is used to predict the fatigue life of the vehicle body. The results show that the fatigue analysis based on modal stress recovery can accurately identify the actual failure location. This method can accurately predict the fatigue life of the vehicle body during the product development stage, providing a theoretical basis for vehicle body design and structural optimization.

Study on the Effect of Tire Wear Level on the Road Load of an SUV ZHAO Hongfei, WANG Dan, HUANG Zhongyuan, ZHAO Feng 2026, 51(5): 70-73，79.  DOI: 10.16638/j.cnki.1671-7988.2026.005.014 Abstract ( )   PDF (1310KB) ( )   The road load (wind tunnel method) in Limits and Measurement Methods for Emissions from Light-duty Vehicles (China 6) (GB18352.6–2016) is obtained by separately measuring the aerodynamic resistance and rolling resistance of the entire vehicle through a wind tunnel. As an important component affecting road load, tires' wear level has a certain impact on both the aerodynamic resistance and rolling resistance of the entire vehicle. Based on the wind tunnel method, this paper simulates different levels of tire wear by grinding tires and conducts a study on the impact of tire wear on the road load of the entire vehicle. The road load test results show that after the tires are worn to a certain extent, the aerodynamic resistance of the entire vehicle changes slightly, the rolling resistance decreases, and the road load of the entire vehicle also decreases accordingly, which is basically consistent with the change trend of tire rolling resistance.This method offers high efficiency, low error, and results closer to real-world conditions, being unaffected by coasting environment interference on actual roads. It can provide valuable data support and insights for subsequent analysis of maximizing range and energy consumption in new energy vehicles. References | Related Articles | Metrics

The development of clean alternative fuels for internal combustion engines and the establishment of novel combustion modes have become critical technological pathways to alleviate the dual pressures of the energy crisis and environmental pollution. This paper investigates the impact of high-reactivity fuel blending ratios (D100、P20、P50) on reactivity-controlled compression ignition (RCCI) combustion using natural gas in a dual-fuel engine. Three-dimensional numerical simulations are conducted under operating conditions of 1 420 r/min speed, 405 Nm load, and 0.18 MPa intake pressure. The results demonstrate that increasing the polyoxymethylene dimethyl ethers (PODE) blending ratio significantly elevates the peak in-cylinder pressure, advances the phase of peak heat release rate, accelerates the reaction rate, and advances the combustion phasing. Owing to its higher cetane number and superior low-temperature oxidation activity, PODE blending markedly shortens the ignition delay period, intensifies reactivity stratification and equivalence ratio gradients, thereby accelerating flame propagation speed and reducing combustion duration. Regarding emissions, compared with D100, P50 reduces total hydrocarbon (THC) and CO emissions by 96.7% and 98.2%, respectively. However, NOX emissions exhibit anincreasing trend due to elevated combustion temperatures.

This strategy calculates the initial required torque through a lookup table method, then performs drive torque limitation and torque coordination to complete torque output. The current vehicle speed is calculated using the driving force-driving resistance model, and the speed-rotational speed relationship is used to feedback the rotational speed and vehicle speed as the input for the lookup table method, forming a closed-loop control to achieve dynamic adjustment of the output torque. Then, the control model of this strategy is built using MATLAB/Simulink, and the control strategy model is flashed into the VCU to be tested. The VCU is connected to the hardware-in-theloop (HIL) simulation bench, and the control logic of the VCU is verified through the HIL bench. The experimental results show that this control strategy can dynamically correct the torque demand based on the driver's intention, vehicle information, etc., and ultimately output a motor torque that meets safety standards and is limited, ensuring the safe and efficient operation of the power system.

Research on the Mechanism of Pickup Skate and Its Influencing Factors WANG Changqing 2026, 51(5): 98-103.  DOI: 10.16638/j.cnki.1671-7988.2026.005.019 Abstract ( )   PDF (1279KB) ( )   For pickups equipped with rear leaf-spring drive axles, rear-axle skidding is prone to occur when driving on rough roads. This paper analyzes the mechanism of skidding and proposes measures to mitigate it. Based on the correlation between skidding and rear-axle reverse hop, a theoretical model of reverse hop is established to analyze its natural frequency and the factors influencing its resonance amplitude. The theory proves that the shock absorber span has a greater influence on the reverse-hop amplitude than the damping force coefficient, and that an optimal damping force coefficient exists to suppress the amplitude, which is not necessarily better when larger. The damping ratio corresponding to this optimal damping force coefficient is compared with the optimal suspension damping ratios targeted at comfort and safety, and the results show that the optimal damping ratios of shock absorbers corresponding to different performance requirements are different.

Analysis of the Cracking Problem of the Longitudinal Beam of a Certain Car Model under Rolling Pressure WANG Weixuan 2026, 51(5): 110-114.  DOI: 10.16638/j.cnki.1671-7988.2026.005.021 Abstract ( )   PDF (3848KB) ( )   To investigate the occasional cracking of the frame longitudinal beam of a certain vehicle model during the roll forming process, this paper adopts the fault tree analysis (FTA) quality tool and focuses on the investigation and analysis of the physical and chemical failure analysis of faulty parts, the surface state inspection of coil raw materials, and the entire roll forming process of longitudinal beams. The results show that the main cause of the cracking of frame longitudinal beams during roll forming is the presence of cold scratches on the inner ring of the material, and such cold scratches are induced by coil loosening, equipment scratch, handling collision and other factors. By optimizing the packaging method of raw materials to reduce scratches during handling, standardizing the recoiling process and cutting off material sections with severe scratches, and additionally setting up special visual inspection for uncoiling before production and grinding repair procedures after water washing in the subsequent processes to ensure no severe scratch defects on the material before roll forming, the cracking of the material during the roll forming process can be effectively avoided.

Practice and Exploration of Ideological and Political Education in Automobile Chassis Structure Curriculum CHEN Dongdong, WEI Qingguo, HAN Wenyan, HAN Shaojian, ZHANG Yudong 2026, 51(5): 137-143.  DOI: 10.16638/j.cnki.1671-7988.2026.005.026 Abstract ( )   PDF (1272KB) ( )   With the rapid development of the automotive industry and the deepening of "new engineering" initiatives, the automotive chassis construction curriculum, as a core curriculum in automotive engineering profession, urgently requires educational reforms that integrate ideological and political education to achieve the fundamental goal of "cultivating virtue and nurturing talent". Currently, while there have been some achievements in the research of ideological and political education in Automotive Construction curriculum, there are still shortcomings in terms of innovative teaching concepts, content integration, and practical methods. This paper takes the North University of China Formula Student China as a practical platform, employing diversified teaching methods such as case-based teaching, project-driven, and virtual simulation to systematically integrate ideological and political elements into the teaching of the Automotive Chassis Construction curriculum. Through comparative analysis of data such as student grades, competition award rates, and employment quality before and after the teaching reform, finds that ideological and political education significantly enhanced students' professional competence, practical abilities, and occupational identity. This research provides a referenceable path and methods for the practical implementation of ideological and political education in curriculum in similar engineering disciplines, holding significant implications for promoting the high-quality development of automotive engineering education.

Teaching Reform of Automobile Structure Teaching Based on Life Cases and AI Assistance LIU Minghao, PENG Shanshan, WANG Xiaoyan, LIU Gan 2026, 51(5): 144-147.  DOI: 10.16638/j.cnki.1671-7988.2026.005.027 Abstract ( )   PDF (2569KB) ( )   Against the background of "new engineering", the course of Automobile Construction is confronted with such problems as fast teaching pace, outdated teaching content and single teaching method. Focusing on the teaching reform of this course, this paper proposes a dual approach: integrating real-life cases into teaching content and combining artificial intelligence (AI) technology to assist teaching. By adopting comparative teaching with similar principles in daily life for example, explaining the principle of valve clearance by why electric wires are not stretched tightly in summer the threshold for students understanding is lowered. With the help of AI platforms, teaching resources such as course PPTs and teaching videos can be uploaded, and students learning status can be fed back in real time, promoting the transformation of teaching from "teacher-centered instruction" to "student-centered self-learning". Teaching practice shows that the reform has effectively enhanced students learning initiative and self-learning ability, optimized the curriculum organization and evaluation mechanism, and provided a referable path for the teaching of structural courses in engineering.
