Abstract

Based on transfer matrix method for multibody system, the dynamics model of a certain multiple launch rockets system (MLRS), the topology figure of dynamics model, the numerical dynamics simulation system are established, and the dynamic characteristics of MLRS in different working conditions are compared. Then continuous variables for joint optimization are designed for firing orders and firing intervals, combining with the Genetic Algorithms, the optimal design of firing orders and firing intervals for the purpose of the best firing dispersion in different working conditions is focused in a real case. The results of simulation show that the firing dispersion has been improved more than 30%. Based on chip microprocessor technology, a self-adaption firing device is manufactured, which receives good achievement in engineering application. Thus, the launch technique of variant firing orders and variant firing intervals for MLRS has been realized.
