摘　　要：从边界元基本方程出发,导出了多弹性体接触问题的边界积分方程和数值离散技术,并用FORTRAN语言编制了计算程序。应用所编程序计算了16m^3大型挖掘机的滚盘压力分布和履带损坏应力分析。A boundary integrate equation and its discrete technique for multi-body contact problem is carried out on basic equations of boundary element method and its fortran program is compiled. Using the method ,the press distribution on the roller plate of the huge excavator with capacity 16 m3 was calculated and a distroy stress analysis of caterpillar of the excavator was carried out.
