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ReeurDyn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-火炮系统高低向筛仰角振动待性进行仿真研究。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、

(Department of Mechanical Engineering, Academy of Amored Force Engineering, Beijing 100072, China) Abstract: 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 RecurDyn 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.
Key words: tank chassis-gun system; dynamics co-simulation; pitch error angle; vibration response
目前，针对坦克底盘-火炮系统动力学的研究大都基于数学理论推导或试验经验理论，史力晨[1-3]等人忽略高速履带本身的振动影响，建立了坦克底盘-火炮耦合系统动力学解析模型．所建模型精度不高，仿真结果无法准确描述火炮的振动特性；周启煌、单东升[46]等人通过实车试验和多次

线性化理论假设建立炮控系统半实物系统仿真模型，模型中坦克底盘对火炮的振动激扰描述不够准确，而且对于没有物理样车的对象无法开展研究工作，为了更加科学的描述稳定工况下火炮的振动特性，通过分析数据输人、输出接口关系，结合 RecurDyn和MATLAB建立坦克底盘-火炮系统动力
