摘要
准确计算自行火炮的振动特性是发射动力学研究的重要内容。将自行火炮处理为由多个刚体、集中质量、弹性梁按一定方式铰接而成的刚弹耦合多体系统,建立了自行火炮的动力学模型,用多体系统传递矩阵法计算了其振动特性。计算结果与试验结果吻合较好。文中的方法可方便地推广到其它武器系统和各种机械多体系统。
It is one of the most important contents to accurately compute the vibration characteristics of self-propelled artillery in the launch dynamics study. Self-propelled artillery is looked on a coupled rigid-flexible multibody system which is made up of some mass-points, rigids and beams in a especial linking mode. A launch dynamic model of self-propelled artillery is established. The problems computing vibration characteristics of self-propelled artillery is resolved by using Multibody System Transfer Matrix Method (MSTMM). The results got by computation and mode tests show good agreements. The method can be easily used in other weapon systems or series of mechanics system.
