【Abstract】 The swb-structure method is introduced to the 3 -D finite element analysis of rolling bearings. The condensation about rigidity equations, the introduction of boundary conditions and the principle and method of iterating solution of rigidity equations are dealt with, and the stress is in the 4-row tapered roller bearings and the housings used in cold-roll mill numerically calculated and analyzed.更多还原
