摘要
利用Archard磨损模型计算含间隙机构中的轴磨损,并获得磨损轮廓。利用ADAMS软件建模仿真,研究了磨损间隙对系统动力学特征的影响。随着磨损间隙的变化,轴孔中心之间的加速度响应幅值呈逐渐增加趋势,高幅振动位置随磨损间隙的增加发生一定规律性的变化,即磨损程度与系统振动的振幅和振动时间密切相关。最后通过自制的含间隙曲柄滑块试验装置验证了以上结论。
The Archard wear model was used to calculate the journal wear in the mechanism with clearance,and the wear profile of joint was obtained.The dynamic changes caused by the irregular wear clearance caused by journal wear were studied by ADAMS dynamic simulation software.With the change of wear clearance,the response amplitude of acceleration between the center of journal and bearing shows a trend of increasing gradually,and the position of high vibration amplitude changes regularly with the increase of wear clearance,that is,the wear degree is closely related to the amplitude and time of system vibration.Finally,the above conclusions are verified by a self⁃made experimental device with clearance slider⁃crank.
