摘要
为了制定有效载荷设计和验证所需要的低频振动环境条件，需要通过耦合动力分析给出有效载荷与运载火箭连接界面的加速度响应。本文利用自由界面模态综合技术研究有效载荷／运载火箭的耦合分析问题，给出了连接界面分别为刚性连接和弹性连接情况下计算有效载荷界面加速度响应的子结构模态综合方法的两种形式。
For defining the environmental testing conditions of low frequency vibration which are needed for payloads design and verify, the acceleration responses of payloads and lapnch vehicle interfaces need to be given using interactive dynamic analysis. In this paper, the problems of dynamic analysis of payloads and launch vehicle interaction are investigated using component mode synthesis technique of free interface modes. Two forms of substructure mode synthesis methods for computing the response of payloads interface's acceleration when the joint interfaces are separately rigid joint and elastic joint are given.
