摘要
本文就坦克在不平地面行驶时坦克—火炮系统的振动问题进行了动力学分析与建模 ,主要包括 :通过随机抽样法建立双侧不平地面模型 ,采用状态方程法建立三维车体、双侧任意车轮、任意位置座椅在内的坦克底盘的振动模型、车体与火炮的相互作用模型 ,并进行了仿真。本文的分析方法将坦克车体的振动对火炮运动的影响体现出来 ,更加全面和客观地反映了坦克行进过程中火炮的运动机理。通过对不同参数的仿真结果进行分析 ,能够定量地得到各参数变化对坦克—火炮系统在行进间的稳定与射击的影响程度 ,这对于坦克—火炮系统的设计与优化有着积极的作用。
Vibration of a moving tank-gun system on an irregular surface was studied in this article. Based on dynamic analysis such models were established as: double side road irregularity model, dynamic model of the chassis based on state equation including three dimensional hull, double side road wheels and seats position at will, and the interaction model between chassis and gun. Digital simulations based on these models were performed. In this way, the influence of the chassis to the gun was considered, so influence of vibration of the gun on the tank can be described better. Quantitative analysis for the influence of the tank-gun parameters to vibration can be made by changing the values of the variables to get different simulation results, so it can take an active role in tank-gun system design and optimization.
