PLANAR MOTION v_s/ a_s SIMILAR VECTOR INSTANTANEOUS FIELD- ~(β,R) u_s VECTOR FIELD

摘要

In this paper we have studied the planar motion v_s/a_s similar vector instantaneous field as a particular application of the ~(β,R)u_s. The three grapho-analytical methods that have been proposed for generating the (v_s)/(a_s) field use the instantaneous graphical kinematic invariant as graphical operators. These methods represent the starring point for new kinematic v_s / v_s and as analysis methods of the planar mechanisms, Unlike the existing methods for the same purpose that either use geometrical transformation through similarity or are used in elements' plane on the scale-sized mechanism, the OKI is more expedient. It allows determinating, at the same time, the unknown (v_s) /(a_s) vectors of the driven elements' points and the ω/? of the driven elements. We consider that GKI methods, used in conjunction with computer graphics, become a powerful tool for the v_s/ v_s and a_s analysis of a planar mechanism.
