ANSYS simulations demonstrate a maximum stress of 154.88 MPa in the frame torsional operating conditions and a first-order modal frequency of 29.49 Hz to avoid excitation interference. Physical vehicle testing confirmes a top speed of 70 km/h, 35 km range, 3 m turning radius, and stable 20 km/h emergency braking without deviation. The research validates the engineering feasibility of lightweight technology, proposes an integrated technical pathway of "simulation-testing-manufacturing" for new energy vehicle, and establishes a replicable industry-education collaborative practice framework.

A vehicle model is established in a dynamic simulation environment, and a vehicle rollover warning system is developed based on the vehicle's centerof-mass sideslip angle, the lateral-load transfer rate (LTR), and the time to rollover warning (TTRW) according to the rollover boundary tested. Considering driver habits, a two-stage warning mode using indicator lights and buzzers is adopted to establish the vehicle rollover warning system model. Simulation results demonstrate that the fully loaded vehicle can trigger the indicator light warning more than 1 s in advance and activate the buzzer more than 0.5 s in advance, while avoiding frequent false alarms. This lays the foundation for subsequent vehicle lateral stability control. References | Related Articles | Metrics

Analysis and Optimization of Resonance Noise in Electric Vehicle WEI Xiwen, MO Xingming 2025, 50(17): 61-65,70.  DOI: 10.16638/j.cnki.1671-7988.2025.017.012 Abstract ( )   PDF (1980KB) ( )   During the road tests of a certain pure electric multi-purpose vehicle (MPV) model in the research and development stage, the vehicle emittes a distinct 480 Hz beeping "whooshing" sound under acceleration, coasting and constant speed operating conditions, indicating poor sound quality inside the vehicle. Through spectral analysis, it is confirmed that there is a distinct resonant band in the 480 Hz frequency band for the noise inside the vehicle under all three operating conditions. Through filtering and playback, it is determined that this resonance band is the fundamental cause of leading to the "whooshing" sound. Through investigation, the issue is traced to the excitation of the drive motor's constrained mode resonance during vehicle operation. Ultimately, by optimizing the installation structure of the drive motor, on the one hand, the rigidity of the installation bracket is enhanced, and on the other hand, the original two-point installation method is improved to threepoint installation and fixation to solve the noise problem. After optimization, the constrained mode frequency of the drive motor increases from 480 Hz to 580 Hz, significantly improving the inside the vehicle "whooshing" noise and meeting the design target requirements.

Study on Fatigue Strength of Automotive Wire Harness Terminal Crimping ZHENG Weihong1 , GONG Yingyu 2 , WEI Chenxi2 2025, 50(17): 71-79,124.  DOI: 10.16638/j.cnki.1671-7988.2025.017.014 Abstract ( )   PDF (5272KB) ( )   As a core component of the automotive electrical system, the reliability of the terminal crimping points in automotive wire harnesses directly relates to vehicle performance and driving safety. Conducting research on the fatigue strength of terminal crimping points holds significant engineering value for ensuring the stable and reliable operation of automotive wire harnesses during long-term service. This paper adopts a method combining vibration tests, fatigue strength tests, and working condition simulations. Targeting common typical scenarios in the process of vehicle driving, such as acceleration, deceleration, turning, and bumping, it constructs a terminal simulation model that conforms to actual operating conditions. With the help of ANSYS software, it simulates and analyzes the vehicle's movement process, focusing on studying the displacement changes, stress distribution, and fatigue strength characteristics of the terminal crimping points. The research reveals that under normal vehicle driving conditions, the stress level at the terminal crimping points is low, and the rate of fatigue damage accumulation is slow; however, under bumpy working conditions, the stress at the crimping points rises sharply, leading to a significant acceleration in the rate of fatigue damage accumulation. The research results can provide theoretical basis and technical support for the design optimization, processing technology improvement, and manufacturing quality control of automotive wire harnesses.

Research on Innovation of Talent Training Model for New Energy Vehicle Inspection and Maintenance under the Leadership of New Quality Productivity LI Zhenhua 2025, 50(17): 125-130,140.  DOI: 10.16638/j.cnki.1671-7988.2025.017.024 Abstract ( )   PDF (1163KB) ( )   Against the backdrop of new productive forces accelerating the reshaping of the new energy vehicle industry, the transformation toward intelligence and greenization is placing subversive demands on the knowledge, skills, and qualities of maintenance talents. This research focuses on the core contradiction where talent cultivation lags behind technological iteration. Based on the connotation of new productive forces as "innovation-driven, digitalized, and high-quality," it systematically analyzes their impact on industrial technological changes and talent demand. Addressing structural deficiencies such as outdated curricula, disconnection between education and industry, and mismatched capabilities, the study proposes a "CPIES" five-dimensional collaborative cultivation framework with a "technology-sensitive curriculum model" at its core. Through distinctive designs such as vehicle-cloud integrated training and virtual-real fusion for hazardous scenarios, a new paradigm for cultivating maintenance talents with "technical comprehensiveness+digital literacy+innovative adaptability" is established. Implementation analysis shows that this model shortens the curriculum update cycle, improves the mastery rate of core skills, and enhances enterprise satisfaction, providing an effective path for vocational education to respond to the needs of new productive forces|.

Artificial Intelligence Empowers Reflections on Curriculum Restructuring and Teaching Transformation FENG Jinping1 , ZHANG Aichun2,3* 2025, 50(17): 135-140.  DOI: 10.16638/j.cnki.1671-7988.2025.017.026 Abstract ( )   PDF (1122KB) ( )   As artificial intelligence (AI) becomes increasingly deeply involved in and transforming the world, the pattern of social division of labor among workers will gradually be changed. This trend puts forward new requirements for the knowledge, ability and quality of engineering talents, and urges the reform of curriculum system and teaching mode. The training objectives should focus on cultivating innovative capabilities and quality development to meet societal needs in the AI era. The restructuring of curricula must integrate interdisciplinary knowledge to enhance students' innovation capacity, foster their skills in applying and developing AI technologies, and strengthen education in AI and engineering ethics. The transformation of teaching methodologies should leverage AI and other emerging technologies, capitalize on the advantages of reverse project-based learning, provide personalized and customized training models for engineering students, and create flexible learning and practical scenarios. This paper offers insights for cultivating innovative engineers in the AI era who are committed to serving humanity. References | Related Articles | Metrics
