Abstract

A system of elastic bodies is examined. It is assumed that the displacements and deformations are small. Firstly, the minimum of maximum pressure and other mechanical values (torque, frictional power loss) are sought by controlling the distribution of contact pressure. Secondly, the optimization problem for roller bearings in rolling state will be discussed and the optimization problem for the wearing process will be formulated as well. For the solution of the optimization problems special iterational algorithms have been developed. In order to solve the contact problem we use both the total potential energy with augmented Lagrangian technique and the modified complementary energy. The p-version of the finite element method is applied for the first problem type, while in the second case an iterational algorithm is developed which includes Kalker's KOMBI program. Numerical examples demonstrate the efficiency of the proposed iterational procedure.
