| Abstract: | In this paper the frequency-domain method for dynamic analysis of payloads and Launch vehicle interaction which is expressed by the coupling FRFs and the acceleration responses of interfaces of launch vehicle without payload is derived using the FRF's synthesis technique. The expressions of coupling FRFs which are formed by the modal parameters of launch vehicle with free interface and of payload with free interface or fixed interface are given. The acceleration responses of interfaces between different pay-loads can be transformed using the coupling FRFs. This method is suitable for the disign departments of payloads to conduct the dynamic analysis of interaction under the action of random excitation. |
