摘要
在文［１］的基础上，本文着重给出了含Ｒ、Ｐ副空间连杆机构摆动力完全平衡条件的构造步骤，按照该步骤，由文［１］所给出的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，可直接构造出含Ｒ、Ｐ副空间连杆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。最后以一两环含Ｒ、Ｐ副空间连杆机构为例，具体说明了用质量矩替代法构造含Ｒ、Ｐ副空间连杆机构的摆动力完全平衡条件的过程。
This paper, together with its companion 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 proposes a general procedure for formulating the condition for complete shaking force balancing of spatial linkages involving R and P pairs from the condition and the formulae for mass moment substitution of RR link, PR RR link group and spatial open chains involving R pairs given in part 1 of paper . The complete shaking force balancing of a 2 loop spatial linkages involving R and P pairs is taken as an example to illustrate the application of the mass moment substitution approach. This work simplifies the formulation of the conditions for complete shaking force balancing of spatial linkages involving R and P pairs.
