| 摘 要： | 为了解决刹车机轮振动给机轮组件和刹车装置造成的严重破坏,以刹车机轮为研究对象,建立机轮刹车振动系统力学模型,采用ABAQUS软件对该振动过程进行仿真,提取机轮的固有频率,将仿真结果与试验结果进行对比,得出机轮试验系统出现共振是其产生严重振动的原因。据此提出了改变卡槽数量和增加垫片等优化方案,减小或隔离振动的传递,减轻了刹车力矩的波动,减缓了机轮的振动,并改变静盘受力和组合受力频率,避开机轮的固有频率,避免机轮试验系统出现共振,使机轮的气缸座振动加速度减小了8倍,位移减小了6倍,大幅度减弱了振动程度,提高了该型机轮的使用寿命。

| Abstract: | A serious vibration will happen when a brake experiment upon the aircraft wheel is done on the test-bed.The serious breakages will appear on both the module of aircraft wheel and the brake device.To solve the problem of the aircraft wheel vibration,the research on the aircraft wheel is conducted and a mechanical model of the brake vibration system is established.Based on the software of ABAQUS,the vibration process is simulated,and the natural frequency of the aircraft wheel is picked up.The comparison betw... |
