摘要
采用I DEAS软件平台构建了 12 2mm车载炮实体模型 ,得出一系列动力学参数。运用多体动力学的Kane方法 ,结合计算机符号推导公式 ,建立了车载火炮发射系统的 9个自由度动力学模型 ,进行了总体结构动力学仿真。数值计算真实地描述了系统的受力状况及运动规律 ,并进行火炮射击稳定性分析 ,为火炮总体设计提供依据。
The paper adopts the I-DEAS software platform in establishing a model for the 122 mm automobile carried howitzer, and acquires a sequence of dynamic structure parameters. The launching dynamics model based on Kane's equation and computer algebraic computation method with 9 degrees of freedom was presented. Dynamic imitation for the overall structure was made. Modeling theory and numerical method were probed for the loading and dynamic responses of the multibody system. Stability of firing howitzer was discussed, and can be of reference in howitzer's system design.
