Abstract

The virtual prototype of multiply rocket launch system are built with dynamic simulation software-ADAMS. Constraining relations among rigid bodies are simulated. Exterior force caused by multiply rocket launch system firing is analyzed. Dynamic simulation is carried out when rocket firing. Curves of initial displacement of direction pipe and curves of initial velocity and acceleration of rocket projectile changing as time are obtained. It can provide a theory foundation for evaluating dynamic characteristics of rocket launch system such as initial interference and improving its performance.
