Abstract

This study presents a simple approach for balancing the slider-crank mechanism that is transformed by four-bar linkage mechanism, applied to design the piston-cylinder mechanism. Due to the shaking force acting on the mechanism frame, the slider-crank mechanism is vibrated during its operation which results in reducing the machine performance. To balance mechanism, the shaking force is minimized by using a counterweight. The counterweight is designed and located at the opposite side of the crank part to balance the shaking force during the mechanism operation. The shaking force equations are established to investigate the influence of counterweight parameters on the shaking force. The shape and size of suitable counterweight are determined based on the simulation results. The single piston-cylinder mechanism with suitable counterweight is designed following the simulation result to validate the calculation process. Finally, the counterweight design flow chart is expressed, which can be used to balance any slider-crank mechanism applied to machine design.
