摘要
用ADAMS10.1版增加的履带工具箱(ATV),建立了某自行火炮的多体系统动力学模型。该模型每条履带系统由一个诱导轮、6个负重轮、1个动力轮、3个托带轮和84块履带板组成,整个模型共有1051个自由度。详细分析了诱导轮、负重轮、动力轮、托带轮和履带板的受力状态,就下列4种情况在硬路面上进行了动力学仿真:一、双侧动力轮设定同样的转速,使自行火炮越过一障碍;二、双侧动力轮设定同样的驱动力矩,使自行火炮在平坦硬路面上行驶;三、一侧动力轮设定驱动力矩,另一侧动力轮设定驱动力矩为0,使自行火炮在平坦硬路面上转弯;四、两侧动力轮设定大小相等、方向相反的驱动力矩,使自行火炮在平坦硬路面上转弯。通过以上分析,得到定量分析自行火炮越野性能、动力性能和机动性能的依据。
In this paper, a dynamic model of a self-mechanized gun is created by adding rotating gun turret, cradle assembly and recoil gun barrel to the tank model in ATV. There are 2 track systems in this model and each track system is constituted of 1 idler, 6 roadwheels, 1 sprocket, 3 support rolls and 84 segments. The whole model has 1051 freedom degrees. The forces acting on the idler, roadwheels, sprocket, support rolls and segments are discussed in detail. 4 simulations are implemented under the following conditions: (1) setting the same rotation speed for the 2 sprockets, letting the gun cross an obstacle. (2) setting the same drive torque for the 2 sprockets, letting the gun run on a plain road. (3) setting drive torque for one sprocket and 0 for another sprocket, letting the gun turn on a plain road. (4) setting drive torque for the two sprockets with the same amount and different sign, letting the gun turn on a plain road. Based on the above analysis, the capability of the gun can be judged quantificationally.
