SYNTHESIS OF PLANER EIGHT BAR MECHANISM FOR FUNCTION AND PATH GENERATION
Journal Title: GRD Journal for Engineering - Year 2016, Vol 1, Issue 12
Abstract
Linkages have an advantage of easily modifying their output by suitable adjustments compared to cams and geared mechanisms. But at the same time it is usually difficult to change the dimensions of mechanisms every time to do different tasks. Also we cannot synthesize exactly the necessary mechanism because of limitation of maximum precision points. This problem is addressed by using adjustable Crank-Rocker linkages that are capable of generating multiple paths with a simple adjustment of the length of the rocker guider. Little work has been done in the area of synthesis of adjustable four-bar and six bar linkages for function and continuous path generation, especially of adjustable crank-rocker linkages. The present work is an attempt to synthesize adjustable eight bar mechanism to overcome this difficulty. The link lengths are computed using Cheybychev’s spacing and Fruedenstein’s equations. A procedure is developed to compute the values of design variable which satisfies the input – output relationship. Analytical and programmable method is developed in Matlab to generate desired function and path.
