Vibration characteristic is one of important factors influencing firing precision of multiple tandem weapons. In the paper, launch dynamics model, transfer equation and transfer matrix of components, overall transfer equation and overall transfer matrix of system for multiple tandem weapons were established by using transfer matrix method of multi-body system. Simulation code of vibration characteristics for multiple tandem weapon was written, vibration frequency and vibration shape were obtained. Quantificational relation between vibration characteristic and construction parameters was established, which could provide theoretical base for study on launch dynamics and improvement of firing precision.
