摘　　要：振动特性是影响多联装串联发射武器射击精度的重要因素之一。文中应用多体系统传递矩阵法,建立了多联装串联发射武器发射动力学模型和各部件传递方程、传递矩阵、系统的总传递方程、总传递矩阵、系统特征方程。编制了多联装串联发射武器振动特性仿真程序,仿真获得了多联装串联发射武器的固有频率和振型,建立了多联装串联发射武器系统结构参数和振动特性间的定量关系,为多联装串联发射武器发射动力学研究和射击精度提高奠定了基础。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.
