In this paper, a discussion is made about the application of the BEM to the strss analysis of the problems of interference-fit at rotating condition. By means of the relation between the local coordinates on boundary and the absolute coordinates, the boundary integral equation for the stress analysis of two-dimensional elastic problems which is suited for handling the connecting conditions of interface in the interference-fit is derived.The equations of the BEM is established for the stress analysis of interference-fit at rotating condition.and the method of numerical calculation is discussed.In the artical, an example is calculated, and the BEM solution iscompared with the analytic solution. The calculation shows thatthe method in this article is feasible for the stress analysisof interference-fit at rotating condition, the numerical precision of calculation is satisfactory.
