摘要
结合某自行高炮的工程实践,对自行高炮的射击过程进行了动力学分析与研究。把自动机与全炮动态耦合为一体,尝试建立了新的力学模型;同时考虑身管弹性变形,建立了火炮发射时的多刚体动力学模型。运用 Kane-Huston 方法推导了高炮射击时的运动微分方程组,对高炮模型进行了动力学仿真计算与分析,获得了全炮的动态响应。
Dynamic analysis and study on the self-propelled AA gun during the firing is made based on a certain self-propelled AA gun engineering practice,New dynamic model is created by dynamically coupling the cannon and the whole gun as an entity. Considering the elastic deformation of the barrel, the AA gun is simplified into a multi-rigid body dynamic model. The thesis uses Kane-Huston method to deduce the differential equations of movement of the AA gun when firing. A computing program is edited and used to calculate the dynamic model, thus all dynamic data of the AA gun are achieved.
