Shaking Force and Shaking Moment Balancing of Planar Mechanisms with High Degree of Complexity

Most of the research on the balancing of shaking force and shaking moment generated by planar linkages was limited to mechanisms with low degree of complexity. This paper attempts for complete shaking force and shaking moment balancing of planar mechanisms with high degree of complexity. Shaking force is balanced by the method of redistribution of mass and shaking moment by adding gear inertia counterweights. The method is illustrated for Stephenson.s linkage (Mechanism with high degree of complexity) and Atkinson engine mechanism and also for Self-balanced slider-crank mechanical systems. The conditions for shaking moment balancing are formulated by using the copying properties of the pantograph linkage and the method of dynamic substitution of distributed masses by concentrated point masses. These mechanical systems find a successful application in engines, agricultural machines and in various automatic machines
