摘　　要：推导了多弹性体多接触面无摩擦接触问题的边界单元法的计算公式和方法，并编制了相应的ＦＯＲＴＲＡＮ程序。所给出的算例说明对多体接触问题只能根据不同的对象编制不同的多体多接触面计算程序来计算，用两体接触问题的解法近似计算多体接触问题其误差甚大。The computational method and formula of elastic multi-body contact problemwith mult-contact surface by boundary element method were carried out and the correspondingfortran program was eompiled as well.The example,given in the paper,shows that the spocial multi-body contact with multi-contact surface program must be compiled for special multi-contact problemaccording to different object.Using the method for solving two-body contact problem toapproximately solve multi-body contact problem with multi-contact surface will lead to large error.
