brake disc wear check

With the wear rig as the testing equipment,under the dry friction condition and with pin-on-disc sliding wear as research object,the variation of material wear mass with load and rotating speed is obtained in the rotating friction.

以旋转式摩擦磨损试验机为试验设备,以销盘滑动磨损为研究对象,取得了干摩擦试验条件下的材料磨损量与载荷、转速的变化规律。

The establishing methods of physical model and mathematic model of the contact characteristics of surface asperity for pin-on-disc sliding wear were designed,and the testing simulation model of pin-on-disc sliding wear was deduced from the wear debris produced by the asperity contact.

以销盘滑动磨损为研究对象,建立了表面微凸体接触特性的物理模型和数学模型,由微凸体接触产生的磨屑推导出销盘滑动磨损仿真模型。
