摘　　要：提出了含Ｒ、Ｐ副空间连杆机构摆动力完全平衡的质量矩替代法，将含Ｒ、Ｐ副空间连杆机构摆动力的完全平衡简化为ＲＲ构件、ＰＲ－ＲＲ构件组、全Ｒ副空间开链的质量矩替代。本文着重导出了ＲＲ构件、ＰＲ－ＲＲ构件组、全Ｒ副空间开链的质量矩替代条件与公式。由这些质量矩替代条件与公式，按照本文第（二）部分给出的含Ｒ、Ｐ副空间连杆机构摆动力完全平衡条件的构造步骤，可直接构造出一般含Ｒ、Ｐ副空间机构的摆动力完全平衡条件，使得这类机构摆动力完全平衡条件的建立过程大为简化。This paper presents a mass moment substitution method for complete shaking force balancing of spatial linkages involving R and P pairs. The complete shaking force balancing of spatial linkages involving R and P pairs is reduced to the mass moment substitution of RR link, PR RR link group and spatial open chains involving R pairs. This paper focuses on the derivation of the condition and the formulae for mass moment substitution of RR link, PR RR link group and spatial open chains involving R pairs. From these conditions and formulae, the conditions for complete shaking force balancing of spatial linkages involving R and P pairs can be formulated in an easy and direct way following the general procedure proposed in paper (to be published). This work simplifies the formulation of the conditions for complete shaking force balancing of spatial linkages involving R and P pairs.
