考虑最小转动惯量选取空间机构振动力平衡配重的方法

Chosing Method of Force-Balanced Counterweights for Spatial Linkage Shaking on Account of Minimum Rotating Inertia

本文在空间机构振动力完全平衡理论的基础上,提出了利用变分原理选取空间机构振动力平衡时各构件配重大小和质心位置的方法。此法计算出的配重具有最小转动惯量,因此可降低机构的振动力矩。文中详细讨论了具有不同连架副的连架杆和非连架杆所加配重的选取方法,并以空间RRRRS五杆机构为例,说明了本方法的应用。

This paper presents design equations and techniques for chosing inertia counterweights of force-balanced spatial linkages with minimum moments of inertia. The inertia counterweights determined by this method can reduce the shaking moments of spatial linkages. The counterweights of the links connected or unconnected with frames are discussed. The application of this method is described by an example.
