减轻重型汽车对道路的损伤─—汽车悬架优化设计

The alleviation of Damage to Road by Heavy Vehicle──Optimization Design of Vehicle-suspension

车辆对道路的损伤取决于其作用在道路上的轴荷（包括静态轴荷和动态轴荷）。本文从改善汽车振动性能，从而减小动态轴荷的观点出发，以减轻车辆对道路的损伤为目的，对汽车悬架进行优化设计分析，并作了实例计算，由此指出在重型汽车后悬架设置减振器是减轻我国道路损伤的有效方法。

The damage to road by traffic depends on the vehicle axle load(bothstatic and dynamic)on the road.This paper presents an optimization design of thevehicle suspension for alleviating the damage to road by improving the vehiclevibration-behaviour so that the dynamic axle load can be reduced.It was shown in theoptimization with example that the installation of a damper in the rear suspensi on ofa heavy vehicle is an effective method to alleviate the damage to road.
