Abstract: LM-8 was China’s first launch vehicle which designed its dynamic characteristics without carrying out a fullscale modal test, and then in the absence of test data to establish the dynamic model. The issue was, how to accurately obtain the mode data of LM-8 with numerical simulations which directly affects the control reliability of flight. In this paper, various approaches to obtain the dynamic characteristics of LM-8 are described from the perspective of refined dynamic modeling and simulating, mode slope prediction, vertical modal test, etc. The numerical simulations were found to be in good agreement with the experimental data, and satisfied the requirements for the engineering application, which effectively supported the successful maiden flight mission of LM-8.
