摘　　要：为了获得各结构参数对某轻型牵引榴弹炮射击稳定性的影响规律,建立了相应的全炮非线性有限元动力学模型.模型中考虑了驻锄与土壤的接触/碰撞,土壤的塑性变形等非线性因素.通过求解不同结构参数的有限元模型,找出对射击稳定性有重要影响的结构参数,在此基础上进行射击稳定性优化.计算结果显示,优化的轻型牵引榴弹炮射击稳定性有效提高.In order to obtain the influence of structural parameters on the firing stability of the lightweight towed howitzer,the corresponding nonlinear finite element models were established. Nonlinear factors,such as contact /collision between the spade and soil,plastic deformation of soil,were considered in the finite element models. By solving the finite element models with different structural parameters,the structural parameters which have great influence on firing stability can be identified. Based on this,the optimization of firing stability was performed.The calculated results show that the optimized firing stability of the lightweight towed howitzer is improved.
