Optimalizált lépésközű Newton-Raphson algoritmus EHD feladat megoldásához

Abstract

Rolling-sliding machines such as gears, cams and followers, and bearings, which are often subjected to high loads, high speeds and high slip conditions when not only the pressure distribution in the lubricant is a question but the surface deformation, and variation of the viscosity due to pressure. To analyse the tribological conditions of the contact surfaces, the generalized Reynolds equation was developed by Dowson. Although several methods have been already developed for solving EHD problems, the solution of the highly nonlinear problem is still quite challenging. Handling the numerical problems during the solution quadratic step optimized Newton-Raphson method has been implemented for solving the nonlinear equation system. The proposed technique reduces the step number during the iteration and the solution is stabilized.
