Analytical Method for Velocity Analysis of Simple and Compound Mechanisms Using Simple Trigonometry

By Pravin S. Ghawade and Nilesh D. Shirgire


mechanisms has been actively studied since the last century. The pioneering work in this field was explored by Reuleaux in the 1870’s and continuous to be a field of active research. Every time, we cant be dependent totally on graphical working of any thing in the universe, it leads thing to take much time with less accuracy. Also Graphical method is inconvenient for Drawing. So we have developed such a Analytical method using Trigonometry for Analyzing the simple & compound mechanisms which will be helpful for the design engineer to carry out the research work in the Industry by reducing the maximum graphical work. Initially this method requires initial position of mechanism or angle of each links with horizontal Axis which also needed in Graphical Method. The focus of this paper is to draw manually velocity diagram on X and Y axis without using any drawing instruments for determining the Linear or Angular Velocities of links for analysis purpose of four bar, five bar, Six bar, Seven bar linkages etc

Topics: Six Bar, Space Diagram, Manually drawn Free Velocity Polygon on X & Y Axis, Triangles etc
