With increasing level of affluence of mankind every day, engineers are facing phenomenal challenge in applying technology for their ever increasing needs and therefore investigate the possibility of improving the performance and efficiency of machinery. In this context, the focus of research is on decreasing the vibrations generated in the mechanisms of machinery. Hence there exists a need of developing a method to equilibrate a spatial mechanism by optimum redistribution of link masses. The evaluation of the kinematic parameters of a mechanism is necessary for the estimation of shaking forces & moments. The main focus of this work is to find & analyze the displacement, velocity and acceleration of all the links of a RSSR mechanism, spatial slider crank mechanism in one complete revolution of the corresponding driving link. The concept of dynamically equivalent system is applied to reduce the shaking force (SF) and shaking moment(SM) in a spatial mechanism by the application of genetic algorithms.
