摘　　要：本文提出了球面机构摆动力完全平衡的一种新方法——质量矩替代法。可将球面闭链机构摆动力的完全平衡转化为球面开链摆动力的完全平衡。文中导出了二副构件进行质量矩替代的前提条件与公式，球面开链摆动力的完全平衡条件。最后以一种单自由度两环球面机构为例，导出了其摆动力完全平衡条件。This paper put forward a new kind of method—mass moment substitution method,for the complete balancing of swinging force in spherical mechanism.The complete balance of swinging force of the close-linked spherical mechanism can be converted into the complete balance of swinging force of the open-linked spherical mechanism.This paper derived the premise condition and formula for carrying out the substitution of mass moment of two pairs of component part,i.e.the condition of complete balance of spherical open-linked swinging force.Finally,take a kind of two-looped spherical mechanism with a single degree of freedom as an example the condition of complete balance of its swinging force was derived.
