端面接触摩擦磨损试验机的研制

Development of Friction and Wear Test Machine for Face-face Contact

为了研究直升机发动机齿轮的端面垫片的摩擦特性,选择优质的材料和改性方法,研制了一台端面接触摩擦磨损试验机。文中介绍了试验机的设计思想、工作原理和结构特点。该试验机可在一定范围内实行载荷、速度控制,利用虚拟测试软件LabVIEW建立友好的虚拟仪器面板,可完成对摩擦力数据的采集、动态曲线显示及数据保存,该试验机且可以通过修改夹具来实现多功能实验。

To research the tribology characteristic of gaskets for gears of helicopters and choose perfect materials, a friction and wear test machine for face-face contact is introduced in this paper which consists of the design means, principle and configurative characteristics of the machine. The test machine can work in a range of loads and speeds and uses the virtual instrument development platform LabVIEW to carry out the data acquisition of friction, the display dynamic curve and the data saving.
