Dynamic Simulation Analysis of Mobile Missile Launching on the Move

By ways of the numerical simulation,it analysis the dynamic performance and the feasibility of the mobile missile launching on the move.It creates the three-dimensional randomly earth-rock road model based on the power spectrum density function of the road and random number theory.It builds an integration model of the system for running and launching based on the virtual prototype technology and finite element method.It does the dynamic simulations for the launch on the move under different velocities and rank road conditions.It obtained the dynamic response of the track and device,the overload and motion characteristics of the missile,the influencing law to the launching of the velocity and road condition factors.The research results show that launch on the move have limit on the vehicle velocity and road condition.
