摘　　要：针对某型轮式装甲车在沙漠或戈壁环境下,因减振器球头经常脱落、锈蚀甚至折断而影响车辆正常使用的问题,首先分析了球头故障机理,并提出了改进措施;然后将车辆1/4悬架动力学模型简化为二自由度模型,并建立了其仿真模型;最后对改进后的减振器进行了强度分析和实车试验。结果表明:改进措施对某型轮式装甲车减振器强度影响较小。The ball-joints of shock absorber in a certain wheeled armored vehicle always shed,rust,or break when used in desert and Gobi,which affects the use of armored vehicles.This paper firstly analyses the fault mechanism of ball-joints,and puts forward improvement techniques.Then the 1/4 suspension dy-namic model of armored vehicle is simplified as a two-freedom model,and a simulation model is built. Through stress intensity analysis and experiment of the improved shock absorber,it can be proved that the improvement has little effects on the intensity of shock absorber in a certain wheled armored vehicle.
