摘要

对牵引车-半挂车纵向载荷传递的分析提供了牵引车单元和半挂车单元之间载荷传递幅度的重要信息。本研究旨在建立一个牵引车-半挂车纵向模型，用于负载传递分析，该模型基于一辆双轴牵引车和一辆通过第五轮悬挂系统连接的单轴半挂车。在MATLAB Simulink软件中对模型进行了仿真，并通过突然加速和急刹车试验，采用定性和定量对比的方法，将仿真结果与TruckSim数据进行了验证。所建立的半挂车模型的动态特性与TruckSim的动态特性吻合良好，均方根误差小于5%。纵向载荷传递分析发现，与突然加速试验相比，急刹车试验中的载荷传递幅度更大，存在时间更长。

Modelling and verification of a 12-DOF tractor-semitrailer longitudinal model for load transfer analysis

The analysis of the longitudinal load transfer in a tractor-semitrailer provides vital information on the magnitude of the loads transferred between the tractor unit and the semitrailer unit. This study aims to develop a tractor-semitrailer longitudinal model for load transfer analysis based on a two-axle tractor and a single-axle semitrailer connected through a fifth-wheel hitch system. The model is simulated in the MATLAB Simulink software and verified using qualitative and quantitative comparison methods between the simulation and TruckSim data through the sudden acceleration and harsh braking tests. The dynamic behaviour of the developed tractor-semitrailer model agrees well with the TruckSim dynamic behaviour with an acceptable RMS error of less than 5%. The analysis of the longitudinal load transfer found that the load transfer during the harsh braking test had higher magnitudes and longer duration of existence than the sudden acceleration test.
