自行火炮多体发射动力学仿真研究

摘要

研究了柔性多体系统动力学参数化建模理论、数值求解方法及其在火炮发射动力学仿真中的应用。利用模态展开法描述了构件的弹性变形，以某履带式自行火炮为例实施了动力学仿真计算，并对结果进行了分析。%This paper is focused on the theory of parametric modeling for the dynamics of flexible multibody systems with applications on artillery dynamics simulation. Modeling theory and numerical method are probed for the dynamic analysis of flexible multibody systems. Elastic deformation is described making use of the mode expansion method. An example of dynamic simulation for the self-propelled gun with caterpillars is given to illustrate the application of the proposed method.
