Study on rigid-body guidance synthesis of planar linkage

In this paper, the guidance-line rotation method of rigid-body guidance is presented. The method effectively solves the rigid-body guidance synthesis problem for the given more than three coupler positions. Using this method, satisfactory four-bar linkages can be obtained such as crank-rocker mechanism, double-rocker mechanism and double-crank mechanism for the given four, five or more than five rigid-body positions. A set of software is developed to realize the automatic design and visualization of guidance synthesis for four-bar linkage, which proves the method to be feasible and effective.
