Abstract
This paper presents a new simple numerical method to solve the non-Newtonian thermal elastohydrodynamic lubrication (TEHL) line contact problem based on real-coded genetic algorithm (RGA). To solve the line contact TEHL problem by means of RGA, the initial population producing method is deeply investigated, an appropriate grid partition method is proposed and an appropriate evolutional computation technology is determined. Finally, the fitness evaluation function and the iterative stop qualifications are put forward. The algorithm is examined by some examples, and the results are compared with empirical solutions. The study shows that the application of RGA in the numerical analysis of the TEHL line contact problem is feasible, reliable and sufficiently accurate.
