一、前言机械产品往往是由许多部件,零件组装而成。因此在机械产品的设计制造中,会迂到大量的接触问题,常常需要比较准确的求出接触面处的应力分布,以得到可靠的强度分析结论。随着我国电力工业的发展,我国自行设计的大型电机也越来越多,××工程中的电机设 First, the foreword Mechanical products are often assembled by many parts and components. Therefore, in the design and manufacture of mechanical products, there will be a large number of contact problems, and it is often necessary to find the stress distribution at the contact surface more accurately so as to obtain a reliable conclusion of strength analysis. With the development of power industry in our country, there are more and more large-scale motors designed by ourselves. The electrical machinery in XX project
