自行火炮行进间动力学模型及仿真研究

本文采用多刚体系统动力学综合技术对自行火炮在行进过程中的运动和受力进行了分析,以自行高炮为例,将系统划分为车体、炮塔、火炮、跟踪平台回转体和跟踪平台俯仰体等五个刚体,各刚体之间存在相对运动,整个系统由悬挂装置和履带弹性支撑在地面上.自行火炮系统具有七个自由度,建立了系统动力学模型,其中动力学方程的最终形式可由程式化软件来完成.对自行火炮在搓衣板型和麻花型路面上行驶时的动力学特性进行了仿真分析,得到了车体俯仰和滚转的运动规律.研究成果对于自行火炮总体设计和运动性能评估具有重要的参考价值.

MODELLING AND SIMULATION OF DYNAMICS FOR THE SELF PROPELLED ARTILLERY RUNNING ON THE ROAD

A method of synthesis of the multibody system dymanics is applied in the kinematic and dynamic analysis of self propelled artillery running on the road. For the self propelled air defense artillery, the system is divided as 5 rigid bodies, viz. the vehicle, the turret, the gun, the tracking rotation platform and the tracking pitch platform. The total system is supported on the ground by the suspension system and the road wheels. The artillery system has 7 D.O.F, and the dynamic model of the system was developed, and the final formulation of the dynamic equations was completed by computer programming. Dynamic properties of the system when running on the washboard-type or the twist-type roads were simulated and the motion of pitch and roll of the vehicle was obtained. The results are important in the system design and dynamic evaluation of the self propelled artillery.
