Transfer Matrix Method for Multibody Systems

13Dynamics of Self‐propelled Launch Systems

13.1 Introduction

The launch process affects the characteristics of weapon systems in many ways, especially the firing precision. The influence of artillery characteristics on the scattering of projectiles can only be evaluated by the initial disturbances of the projectiles as a result of the launching process. The interaction between projectile and artillery during the launch process must be fully considered and the initial disturbance must be accurately computed when analyzing and computing the weapon system. How to solve the difficult problem of self‐propelled artillery is a practical example of the important engineering applications of the linear transfer matrix method for multibody system (MSTMM) introduced in this chapter [106–111]. Self‐propelled artillery weapon systems, which are widely equipped all over the world, are chosen as our study object in this chapter. Using MSTMM, self‐propelled artillery is regarded as a multi‐rigid‐flexible‐body system (MRFS). The natural vibration characteristics of the system are computed first, then the body dynamic equations of the system are established and the augmented eigenvector and its orthogonality are constructed, and finally the dynamic response and initial disturbance of the projectile are solved. The simulation system for the launch dynamics of self‐propelled artillery is also formed, which provides an important tool for the dynamic design to improve the firing precision and other ...
