摘　　要：自行火炮行驶性能是分析车体运动与受力规律,研究车体姿态变化规律的基础。首先,对某型轮式自行火炮底盘行走系统进行了结构分析,建立了轮胎地面接触力学模型、悬挂系统力学模型;然后,应用虚拟样机技术,结合行驶路面数字化模型,构建了底盘行走系统的虚拟样机,并进行了行驶过程仿真;最后结合实车数据,对比分析了相同速度下纵摇角、横滚角的变化规律,验证了模型的准确性。通过行驶过程仿真,获得某型轮式自行火炮的车体变化规律,为后期开展相关的行驶性能试验提供了模型支持。The driving performance of self- propelled gun is the foundation for analyzing the bodywork movement and force rule. In the paper, firstly, the configuration for the wheeled self - propelled gun chassis was analyzed, and the tire -ground and the suspension system mechanics model were studied. Secondly, combining with the running road model, virtual prototype technology was used to build the virtual prototype of the self - propelled gun chassis, and the driving simulation was made. Finally, compared with the test data, the virtual prototype was validated. The research provides the model for the subsequently correlative driving capability test.
