摘　　要：力的平移定理是力系等效的重要方法,其目的是将复杂力系进行等效和简化,从而建立复杂力系的静力平衡关系。本文通过"三幅图、三过程",使力的平移定理的全部过程更加清晰,有利于学生对这一定理的掌握和应用。The theorem of force translation is an important method for forces equivalent.It can simplify a complexforce system by replacing system of forces and couple moments with an equivalent system.The static equilibriumrelationship of the complex force system can be easily established by this method.This paper try to make the wholeteaching process of the theorem of force translation more clear by three pictures and three processes,which is benefit forthe students＇ understanding and application of the theorem.

关 键 词：力的平移 力系简化 教学方法
