[Abstract]:The effects of load, velocity and material parameters on the central pressure and the secondary pressure peak under the linear contact EHL state are studied. Based on the analysis and regression of a large number of numerical solutions, The fitting formulas of the center pressure amplitude and the secondary peak pressure amplitude are given, and the accuracy of the fitting formula is tested. The results show that in a wide range of parameters, the accuracy of the proposed fitting formula is satisfactory and can meet the requirements of engineering design.
