Силовом расчет рычажных механизмов на ЭВМ методом замкнутых векторных контуров

Abstract

The engineering methods of mechanism analysis were mainly based on graphical (approaches lately. At present the possibilities of modem personal computers allow to use (different programs developed specially for quick, qualitative and full design of various (mechanisms. Closed vector loop method permits to apply unified approach to different schemes (of mechanisms under their kinematic analysis and in this way to unify the searching algorithm of (link motion parameters (displacement, velocity and acceleration). In the paper the application of (this methodfor force analysis of the two-dyad link gear has been considered. Two vector loops (have been determined for given mechanism and equations for angular and linear accelerations of (the links have been derived. In order to determine the constraints and gravity forces the force (diagrams have been drawing and the balance equations have been written. The Visual Basic (program for kinematic and force analysis of the two-dyad link gear has been developed and (results of its work has been presented in the paper. The program permits to investigate different (types of mechanisms using closed vector loop method.
