Abstract

The coupled relationship of optimize algorithm and dynamic simulation was established based on launch dynamics simulation model of Multiple Launch Rocket System(MRLS).The launch dynamics simulation and optimization were performed,the best launch time sequence and corresponding support stiffness and damping were obtained and vibration performance was calculated also,all of these verified the valid of optimized parameters.Moreover,the influence of random launch time on initial perturbation was analyzed.The methods and conclusions can be used as a theoretical foundation for development and revise of new MRLS.
