摘　　要：为了对坦克底盘-火炮系统中火炮的振动特性进行准确描述,提出应用多软件联合仿真的方法,分别基于Recur Dyn和MATLAB建立坦克底盘多体动力学模型和炮控系统模型,二者相结合建立联合仿真系统模型;在稳定工况下,对坦克底盘-火炮系统高低向俯仰角振动特性进行仿真研究.结果表明:随路面不平度的增大和坦克行驶速度的提高,火炮高低向误差角变大,稳定性变差;所建联合仿真模型能够很好的模拟火炮的高低向俯仰角振动,联合仿真方法提高了模型的准确度和计算效率,为坦克在不同行驶条件下进行火炮射击提供了定位范围参考.In order to describe the vibration characteristics of the gun in a tank chassis-gun system,a method of the multi-software co-simulation is put forward. The joint simulation system model is established by the combination of a multi-body dynamics model for the chassis in Recur Dyn and a control system model for the gun in MATLAB. The vibration characteristics of the pitch angles in the chassis-gun system are simulated under a steady condition. The results show that the pitch error angle of the gun becomes larger and its stability worse with the increase of both the road roughness and the tank speed.The established model can well simulate the pitch vibration of the gun,the combination method improves the accuracy and the computational efficiency,and the research idea provides a referenced mil range for gun firing under different driving conditions.
