Coupled Vibration Analysis of Multiple Launch Rocket System by Finite Element Method

摘要

In multiple launch rocket system (MLS), initial disturbing is one important factor to influence the firing precision. It is meaningful theoretically and valuable practically to Study and to take right theory and effective calculating methods to analyze the vibration of MLS. Based on Constructive Solid Geometry (CSG) and Finite Element Method (FEM), the elastic MLS modal is built and the coupled vibration response of the system when firing constantly is simulated. In order to verify the availability of researching methods, the conclusions are compared to practical situation. The result provides a reference in MLS design.
