摘要
为了研究坦克底盘-火炮系统在稳定工况下火炮的高低向俯仰角振动问题,建立了坦克底盘多体动力学模型和坦克底盘-火炮系统动力学模型,采用实车试验验证了坦克底盘动力学模型的合理性,通过仿真计算得到不同路面环境和行驶速度下火炮的高低向误差角变化特性。研究结果表明:所建立的坦克底盘-火炮系统动力学模型能够在炮控系统有效的俯仰角度范围内准确描述坦克底盘对火炮俯仰角振动的激扰作用;火炮的俯仰角振动的振幅随车速的提高而增大,随路面不平度的增加而增大。
To study the angular vibration response of tank chassis-gun systems in elevation,multi-body dynamic model of tank chassis and the tank chassis-gun dynamic system model are built,when tank gun control system was working in stable condition. The rationality of the tank chassis multi-body dynamics model is verified by the results of vehicle test. The gun ＇s angular vibration response in elevation is simulated and calculated,when tank is driving at some different driving speed and in different roads. The results show that,the tank chassis-gun dynamics model could express the excitation from tank chassis to gun control system well,when gun control system is working in effective angular range. When tank was running on smooth road,driving speed and road condition were important factor for gun angular vibration.Amplitude of angular vibration will increase with the increasing of driving speed and road roughness.
