Cylindrical straight tooth wear simulation method considering actual tooth surface elastic-plastic contact

The invention discloses a cylindrical straight tooth wear simulation method considering actual tooth surface elastic-plastic contact. The method comprises the steps of establishing a real rough contact cylinder geometric model, and calculating the distance between each pair of contact cylinders based on iteration; calculating the contact pressure and the wear depth of each discrete point and the wear along a meshing line; and after certain abrasion is achieved, conducting morphology updating, micro-convex body group reconstruction and rough cylinder geometric model updating and reconstruction,so that the simulated situation is closer to the real situation of the gear, and thus the abrasion degree, the service life and the like of the gear can be more accurately predicted. 本发明公开了一种考虑实际齿面弹塑性接触的圆柱直齿磨损模拟方法，本发明进行真实粗糙接触圆柱几何模型建立并且基于迭代计算出每对接触圆柱的间距；计算每个离散点的接触压力及磨损深度和沿啮合线的磨损；并且达到一定磨损后进行形貌更新和微凸体群重构及粗糙圆柱几何模型更新重构，模拟的情况更接近齿轮的真实情况，从而能够对齿轮的磨损程度和使用寿命等进行更加精准的预测。
