摘　　要：通过对汽车/护栏碰撞试验室的牵引系统结构进行分析,提出了电力牵引动力系统的设计思路和方法。以18 t的碰撞车辆在80 km/h的速度为前提条件,建立了碰撞车辆的动力学模型和电动机的牵引模型,并基于牵引系统的结构和模型对牵引系统的各参数进行了可行性优化设计。将理论分析计算结果和汽车/护栏碰撞试验室的实际建设情况进行了对比分析。结果表明,该牵引动力系统设计合理,说明了这种设计方法在设计碰撞牵引动力系统时的可行性及有效性。According to the analysis of traction system structure of vehicle/guardrail crash testing laboratory,a design idea and method of the electric traction power system was proposed.Under the precondition that the 18 tons vehicle at a speed of 80 km/h,the dynamic model of the collided vehicle and the traction motor model were established.Based on the structure and model of the traction system,the feasibility of the various parameters have been optimized afterwards.By the comparative analysis between the theoretical analysis results and the actual construction of the vehicle/barrier crash testing laboratory in Changsha University of Science Technology,it was indicated that the traction power system is reasonable,having proven the feasibility and effectiveness of the design method for collision traction power system design.
