Abstract

Launch dynamics simulation model of Multiple Launch Rocket System(MRLS) was established based on Multi-rigid body dynamics and multi-flexible body dynamics theories. The flexible contact model was introduced in simulation model,which could describe the real mechanical characteristics of MRLS. The launch dyanics simulation was performed,the dynamic response of launcher was obtained and the vibration performance was calculated also, simulation and experiment results verify the valid of model and methods. The methods and conclusions can be used as a theoretical foundation for development and experiment of new MRLS.
