Estimation of Vehicle Mass for Distributed Drive Electric Vehicles FENG Yingxia1 , LI Kai1 , LI Huiling1 , LU Guo1 , ZHENG Run1 , HAN Yinfeng2* , LENG Bo3 2025, 50(23): 1-8,19.  DOI: 10.16638/j.cnki.1671-7988.2025.023.001 Abstract ( )   PDF (1131KB) ( )   The total vehicle mass is a critical parameter in vehicle dynamics modeling and control system design, directly influencing the dynamic performance, energy efficiency, and safety control capabilities of electric vehicles. In distributed-drive electric vehicles, due to the rapid response and precise torque regulation of electric drive systems, the impact of total vehicle mass on control accuracy is particularly pronounced. However, vehicles frequently encounter complex operating conditions such as variable payloads during operation. Fixed-mass assumptions can easily lead to model mismatch, thereby compromising the stability and robustness of control systems. To enhance model adaptability and estimation accuracy, this study develops an adaptive Kalman filter to achieve robust vehicle speed estimation, thereby providing reliable speed reference information for mass estimation. Subsequently, based on the vehicle longitudinal dynamics model, an online vehicle mass estimation method is constructed using a recursive least squares (RLS) algorithm with a forgetting factor. By approximating resistance terms, this method reduces dependence on unmeasurable parameters and improves practical feasibility. Simulation results demonstrate that the proposed method achieves high-precision, rapidly convergent mass estimation under typical acceleration scenarios, providing theoretical support for optimizing control strategies in distributed-drive systems.

A simplified method of computational fluid dynamics (CFD) simulation based on equivalent roughness is proposed. A threedimensional corrugated tube model with double right-angle elbows is established, and the pressure drop characteristics under different flow velocities are analyzed using the shear-stress transport (SST) k-ω turbulence model. With an inlet velocity of 1.5 m/s as the calibration benchmark, the accuracy of equivalent simplification methods is evaluated within the velocity range of 0.5 m/s to 2.5 m/s. The results demonstrate that the global equivalence method exhibits a maximum deviation of 15.47%, while the zonal calibration method with 5 characteristic regions and gradient roughness parameters achieves a maximum error of 7.18%. The simplified equivalent smooth tube model reduces mesh count from 1.116×107 to 1.58×105 , significantly decreasing computational load and improving simulation speed, providing an effective solution for large-scale liquid cooling system simulations.

Only the hydrogen supply system and the fan are retained, which respectively provide hydrogen and air for the stack. Based on the problem of poor gas diffusion performance under the ridge in the traditional straight channel, two types of variable cross-section channels, namely the step channel and the side wall constricted channel, are proposed for air-cooled PEMFC, and compared with the traditional straight channel. The effects of the variable cross-section cathode channel on output performance, gas transport in the membrane electrode, water removal, pressure drop and cooling capacity are systematically studied. The results show that the power density of the step flow channel and the side wall constricted flow channel is increased by 6.4% and 7.8% respectively compared with the straight flow channel. The average temperature is reduced by 7.4% and 7.3% respectively compared with the straight flow channel. References | Related Articles | Metrics

Due to the limited internal space, the positions of the module and the battery management system (BMS) cannot be moved, and this problem needs to be solved under the current layout. This study experimentally investigates the impact of densely distributed welds on vibration-induced failures. Through a multi-scheme comparative analysis integrated with finite element simulation, three connection reconfiguration approaches are evaluated: scheme A: bracket-free, scheme B: welded-bolted hybrid, and scheme C, full bolted connection. The results demonstrate that replacing welds with bolted connections significantly mitigates stress concentration effects. The optimized design is rigorously validated via triaxial vibration bench testing, successfully passing vibration tests at twice the national standard requirements. It provides a solution for the compact structure design of high energy density battery pack. References | Related Articles | Metrics

By analyzing its force situation, the relationship between the yield criterion and plastic strain is used as the core fatigue failure criterion. The dynamic response mechanism of the leaf spring mount under full freedom and the insufficient bearing capacity of the reinforcement are revealed through the combined simulation using HyperMesh and LS-Dyna. A parametric geometric optimization method is adopted to optimize the structure step by step, with the thickness of the reinforcement as the variable, incremented by 0.5 mm at each step. The optimized design, with only a 0.75% increase in weight, enables the leaf spring clamp to be in a pure elastic deformation stage under reinforced road conditions, effectively enhancing the structure's resistance to plastic deformation. This can provide a reference for the design optimization of the leaf spring clamp. References | Related Articles | Metrics

Analysis and Optimization of Abnormal Water Flow Noise Problem in Automotive Heat Exchangers ZHONG Xiaolin1 , JIANG Darong2 2025, 50(23): 96-99113.  DOI: 10.16638/j.cnki.1671-7988.2025.023.017 Abstract ( )   PDF (1579KB) ( )   Regarding the abnormal water flow noise problem in an automobile heat exchanger, simulation experiments and other methods are used for cause analysis. Through vehicle bench tests, it is concluded based on theory and experiments that the coolant in the thermal cooling system is locally heated to generate a large number of bubbles. These bubbles enter the heat exchanger through the pipeline, causing abnormal noise in the vehicle. Finally, improvement measures are formulated according to the "source–path–response" noise, vibration, harshness (NVH) control method, and the effectiveness of this method is verified through comparative tests. The research results show that changing the position of the inlet pipe of the heat exchanger and adding a connecting pipe at the top of the thermostat base of the cooling system can discharge the bubbles in the system, which not only ensures the air conditioning heating performance but also solves the problem of water flow noise.

By simulating the erosion environment through ultrasonic cavitation experiments, the mass change of the samples is recorded using the weight loss method, and the Logistic growth curve is introduced to deeply explore the relationship between the cumulative weight loss due to erosion and time. This study explores the influence of the groove microstructure on the erosion resistance of the polyurethane coating of the propeller. The experimental results show that the designed groove microstructure (width to spacing ratio of 2) can significantly reduce mass loss, with the cumulative mass loss of the groove sample being 21.82 mg, approximately 48% of that of the smooth sample. At the same time, the nominal incubation period, acceleration period, and attenuation period of material erosion are clarified. The groove microstructure can significantly extend the incubation period of material erosion, with the nominal incubation period of the groove sample reaching 16.86 h, approximately 2.8 times that of the smooth sample, thus demonstrating excellent erosion resistance. This research can provide a theoretical basis for the anti-erosion protection of the surface of flight vehicle propellers. References | Related Articles | Metrics
