平面连杆机构摆动力和摆动力矩的完全平衡

本文利用质量分布和附加两种惯性配重相结合的方法，实现了平面多杆机构摆动力摆动力矩的完全平衡。这两种惯性配重是定轴齿轮机构（简称为齿轮机构）惯性配重和行星机构惯性配重。笔者先以一种六杆机构为例，说明一般多杆机构力与力矩完全平衡的条件推导过程。本文的重点是根据上述理论进一步提出了铰链多杆机构的分解平衡法，即把该类机构分解成若干个铰链四杆机构和双杆组来分别平衡，从而明显简化了平衡方程的推导过程。

COMPLETE SHAKING FORCE AND SHAKING MOMENT BALANCING OF PLANAR LINKAGES

The paper presents design equations and techniques for the full shaking force and shaking moment balancing of planar linkages. The balance includes all mass effects due to both linear and rotary inertia, but excludes external loads. The method utilized is a combination of mass redistribution and addition of two kinds of the inertia counterweights, which are the feared inertia counterweight and the planetary-gear-train-inertia counterweight. A six-bar mechanism with prismatic pairs is used as an example which shows the general process for deriving the balancing conditions of linkages. According to this theory, we presents the approach of decomposition of the linkages. According to this theory, we presents the approach of decomposition of the linkages only with revolute pairs for the entire force and moment balancing of the mechanisms. It is that the force and moment balancing of the multi-bar linkages only with revolute pairs is changed into the balancing of several four-bar linkages and two-link dyads. An example is included.
