Assessment of stratified functional properties for plateau surfaces

主要结果如下：(1)研制了用于生产高原表面的往复磨损试验机。其滑动长度为300mm，公称接触压力为0.01MPa，采用滴注式润滑器。(2)为了测量间歇滑动试验后同一区域的表面纹理，定位仪采用3基准原理。(3)虽然ISO提出了重复滤波的方法来分离高原轮廓和表面纹理，但研究者明确了该方法会使高原表面轮廓失真。(4)开发了自动制作材料概率图和绘图曲线的软件。(5)提出了一种通过平滑方位曲线分离高原剖面的新方法。(6)明确了以材料比作为参数来表示平台轮廓，并通过磨损曲线验证了其有效性。

The main results are as follows.(1)The researcher developed the reciprocated wear-test machine to produce plateau surface. Its abilities are a sliding length of 300mm, a nominal pressure of contact of 0.01MPa and the dropped type lubricator.(2)In order to measure surface texture at the same area after intermittent sliding test, the relocation instrument applying 3-datum principle.(3)Although ISO presented the duplicate filtering method to separate the plateau profiles from surface texture, the researcher made clear that profiles of plateau surfaces distorted by this method.(4)The researcher developed a software to make material probability chart and plot curves automatically.(5)A new method to separate the plateau profiles was developed by smoothing the bearing curves.(6)It was made clear that the parameter was the material ratio to show the plateau profile and its efficiency was verified by wear curves.
