摘要/Abstract

摘要： 对某型自行火炮结构组成进行分析，利用ATV模块在ADAMS软件平台上建立该火炮的虚拟样机；利用谐波叠加法构建了随机不平路面，实现了自行火炮的仿真行驶。选择总的加速度加权均方根值评价法作为自行火炮行驶平顺性的评价标准，并对不同路面上的行驶平顺性进行仿真计算，得到了评价平顺性的参考值。结果表明，通过建立虚拟样机对自行火炮进行平顺性分析是可行的，为自行火炮的行军试验仿真提供了参考。

Abstract: Based on the computer simulation technology, the virtual prototype of a self-propelled gun was built, and its ride comfort was analyzed. Firstly, after analyzing the structural constitution of the self-propelled gun, its virtual prototype was built by means of Al V toolbox of ADaMS. Secondly, the method of superposition of the harmonic wave was used to build the random rough road, and the ride simulation of the self-propelled gun was carried out. Finally, the total acceleration weighted RMS val?ue method was chosen as the evaluation criterion of the ride comfort of a tracked vehicle, and the refer?ence value to evaluate ride comfort was obtained by simulating riding in different roads. The simulation result indicates that the virtual prototype technology is a feasible approach to analyze the ride comfort of the self-propelled gun, and the ride comfort simulation can offer a valuable reference for the ride testing simulation of a self-propelled gun.
