| 摘 要： | In the design of the fatigue strength of dynamically loaded bearing in the equipments such as internal combustion engines and roiling mills, the solution to the stress distribution on the bushing alloy layer is an important and difficult problem. In this paper, a new method has been proposed by coupling BEM with elasticity method. The algorithm and its implementation were described in details. The calculation results verify that this up-dated method can provide us a more simple and effective tool for solvingtbe fatigue stress of the bushing alloy with tangible benefit of time-saving and high computation accuracy‘. It may open a new vista in bearing fatigue strength design.
