STRUCTURAL ANALYSIS OF THE COMPLEX MECHANISMS OF THE THIRD AND FOURTH CLASSES

Abstract

A structural study of complex plane mechanisms of the third and fourth classes with a degree of freedom W = 1, based on various possible types of structural groups of the third and fourth classes, which take into account the number and specific nature of kinematic pairs and their location in the group Structural analysis is made by a method of conditional change of the leading link of the mechanism, which allows to obtain formulas of structures of kinematically equivalent mechanisms of the second or third classes, which allows to find out the sequence of determination of kinematic parameters of points and links of mechanisms of the corresponding class, to simplify the kinematic analysis and to increase the accuracy of the results of the study ..
