Abstract

With the development of rocket technology, the demand of large draw ratio rocket with big carrying is improved. In this artical, for the purpose of optimization analysis of large draw ratio rocket's dynamic modal characteristics, a finite element model is established firstly. Then the structure of the rocket body is reconstructed and the modal analysis is done with simulation software. Finally, the frequencies of the bending vibration of the structure are obtained by means of finite element analysis. Through the combination with current engineering conditions, the article analyses rationality of the optimization model, which provides an effective method for the optimization of the dynamic modal characteristics of rocket structure.
