摘要
文章针对某卫星存在的局部响应偏大的问题,对通过修改结构参数降低卫星的结构振动响应进行了研究。通过计算卫星响应相对卫星结构参数的灵敏度,得到了卫星结构参数对响应的影响大小,为修改结构来降低响应提供了依据。根据灵敏度分析的结果,选择一定的设计参数进行修改和响应计算,结果表明目标位置的响应得到了改善。
Vibration control with structure modification is studied for reducing the large vibration response in satellite structures.According to the sensitivities of response with respect to structure parameters,the relationship between structure parameters and resonse is obtained.A modification of structure based on sensitivity analysis reduces the vibration response at specified positions.
