机构速度瞬心及瞬心转移速度的研究(3)——广义罗氏定式与瞬心转移速度的求解

Instant Center of Planar Mechanism and Its Moving Velocity (3)—Generalized Lou's Configurations and Solution to Moving Velocity of Instant Center

提出了平面连杆机构速度瞬心转移速度(简称“瞬心速度”)求解的新方法。指出了瞬心速度图与瞬心图的动态同构关系。提出了广义罗氏定式,将求解瞬心的罗氏定式推广到求解瞬心速度。

A new method for finding the moving velocity of an instant center position (for short “instant center velocity”) of planar linkages is studied. The dynamic isomorphic relations between instant center velocity chart and instant center chart are indicated as well. The generalized Lou's configurations for solving instant center velocity are put forward. The Lou's configurations for finding instant centers are generalized to look for instant center velocity. The generalized validity is proved with the projective geometry theory.
