## MATLAB火炮武器振动特性及影响因素仿真研究

Title    Simulation study of artillery weapons vibration characteristics and its influence factors
Abstract
In this thesis,the transfer matrix method theory of multi-body system has been used to study the vibration characteristics of artillery weapon system and its influence factors and simulate them on MATLAB. The main contents of this thesis are as below.
Based on the consists of self-propelled gun,a simplified launch dynamics model
has been set up.Based on Transfer matrix method of multibody system theory, the transfer matrix of the typical components has been derivated and the overall transfer equation and the overall transfer matrix has been established.
Substituted boundary conditions into the total transmission equation of gun system to derivate characteristic equation.Then the vibration frequency of gun vibration system has been Calculated through MATLAB programming simulation. 源`自*六)维[论*文'网www.lwfree.cn
Based on the multivariate linear regression theory in mathematical statistics,the
influence of stiffness of gun attachment parts on its vibration characteristics has been analyzed.
Keywords: Launch dynamics、Transfer matrix, Transfer equation,
Characteristic equation, Natural frequency, Correlation
