在机械中,绝大卫分的机器都是由不少零件构成的,其中有许多的配合面,相互之间受到所谓接触力的作用。不少人对接触力的分布运用古典分析方法进行了研究,但由于问题复杂效果有限。1970年Parsons,B和Wilson,E.A.首次运用有限元素法求解弹性接触问题。之后,用有限元素法研究接触问题的人不断增加,经过几年的努力,现发展了五种计算方 In machinery, the vast majority of David’s machines are made up of many parts, many of which cooperate with each other by the so-called contact force. Many people study the distribution of contact force using classical analysis methods, but due to the limited effect of complicated problems. In 1970 Parsons, B and Wilson, E.A. for the first time using the finite element method to solve the elastic contact problem. Since then, the number of people who have studied the problem of contact with the finite element method has been steadily increasing. After several years of hard work, five kinds of calculation methods have been developed
