摘　　要：为了提升四驱牵引车与半挂车系统的动力匹配及稳定性。分析四驱牵引车在加速状态下的受力情况,建立相应的数学模型。基于计算结果,评估两轮半挂车对四驱牵引车地面附着力的影响,并提出两轮半挂车结构的优化设计,为零部件设计及扭矩控制策略提供重要参考。In order to improve the power matching and stability of the four-wheel drive tractor and semi-trailer system,analyze the force distribution of four-wheel drive tractor under accelerated conditions,a mathematical model was developed.The computational results were employed to assess the influence of two-wheel trailers on the ground adhesion characteristics of the towing vehicle,accompanied by proposed structural optimizations for the trailer configuration.This investigation provides critical references for component design and torque distribution control strategies in such articulated vehicle systems.
