摘　　要：针对某兵器发射塔架摆杆系统运行过程中存在的速度不均(喘行)现象进行故障诊断.首先建立摆杆系统的等效动力学模型,并运用准静态法对该模型进行动力学分析,根据所得动力学方程探究了该摆杆系统的动态特性.结合系统动态特性,通过试验分析并验证了造成喘行现象的故障原因,指出了故障的排除方法.Make fault diagnosis in the overbalanced movement （dyspneaing vibration） phenomena of lauching tower＇s pendulum system. First of all, an equivalent dynamic model is developed. Quasi-static method is used in the dynamic analysis the of the model. The dynamic characteristic id researched based on the dynamic equation coming out of the dynamic analysis. Considering the dynamic characteristic, the test data is used on the research and verification of the fault reason of the dyspneaing vibration, the resolvent method is pointed out at last.
