基于Adams履带车辆工具箱的自行火炮行军试验仿真

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种情况在硬距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变；四，两侧动力轮设定大小相等，方面相反的驱动力矩，使自行火炮在平坦硬路面上转变，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。

Run Simulation of Self-mechanized Gun Using Adams Tracked Vehicle

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.
