Abstract
Abstract The dynamics simulation of the processing of the gun adjustment for multiple launch rocket system (MLRS) as a complex nonlinear multibody system is studied. Based on the new version of transfer matrix method for multibody system (MSTMM), the nonlinear multibody system dynamics model of MLRS is established, and the overall transfer equation of the nonlinear multibody system is deduced. The launch dynamics simulation of MLRS is carried out by combining the general kinematics equations of rocket and Monte Carlo method, and the simulated results are verified by experiments. On this basis, the control design and dynamics simulation of the gun adjustment of MLRS has been preliminary studied by combing MSTMM with PD control method. The results show that the proposed control method has a good stability and can realize the automatic control of gun adjustment of MLRS quickly and accurately.
