Automatic deduction of overall transfer equation and dynamic rapid simulation for a multiple launch rocket system( MLRS) are the key to its dynamic design. Here,a new type MLRS,its multibody system launch dynamic model and topological structure were built. According to sign conventions and transfer equations of elements,an automatic method to deduce the overall transfer equation of the new type MLRS was proposed. Its modeling efficiency and programming level were improved. A dynamic visual simulation system for the new type MLRS was established,its launch dynamic behavior was simulated rapidly and validated with tests. The results provided a theoretic foundation for the dynamic design of the new type MLRS.
