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。
On the basis of [1], this paper focuses on the structural steps of the complete balance of rocking force with R, P subspace spatial linkage mechanism. According to this step, the RR components, PR- RR component group, all R R space open chain mass moment substituting conditions and formulas can be directly constructed with R, P deputy spatial linkage mechanism complete balance of the swing force conditions, making such institutions complete balance of swing force conditions of the establishment process Greatly simplified. Finally, taking the one-two-ring R, P secondary spatial linkage as an example, the process of constructing the complete equilibrium condition of oscillating force with R, P secondary spatial linkage by mass moment substitution method is described in detail.
