Computer Aided Generalized Method of Synthesis of Four Bar Mechanism

A new computerised dimensional synthesis method is described in the paper. To synthesis of a four bar mechanism, knowledge of function, path, motion generation method is required. Synthesis of four bar mechanism depends upon the graphical as well as analytical methods. The graphical approach is suitable for finding out the length of links of a mechanism with two or three precession point. However, to find out the values of link of four bar using three position synthesis analytically at various position it required lots of calculation and it take more time. To get values of all link of a four bar mechanism at different positions of the crank, a computer program is developed. This paper deal with synthesis of a four bar mechanism to determine values of all four link of four bar mechanism at different positions of the crank using digital computer
