【摘要】 采用有限体积法结合多重网格法的FAS格式对普通导轨表面微观凹坑润滑进行了模拟研究,指出了其润滑本质即是流体动压润滑,并实验证实了光滑平面上合适的凹坑确实能够改善润滑,并且凹坑深度对其影响比较大。更多还原

【Abstract】 Uses finite volume method and full approximation scheme of the multi - grid method to simulate the microcosmic potholes lubrication of the sliding guide surface, and points out that the essence is fluid dynamic pressure lubrication, then through the experiment proves that appropriate microcosmic potholes on the surface of the slick surface can improve lubrication assuredly, and the depth of the pothole has an important influence.更多还原
