In this paper, a new procedure for the dynamic balancing of a slider-crank mechanism is presented. First, the inertial properties are represented by equimomental systems of point masses. Then, the acceleration analysis is performed using natural coordinates, which allows us to obtain directly the acceleration of the point masses. The dynamic is solved using the screw theory through Davies’ method. Finally, the shaking screw is proposed, with which the objective function is formulated. The proposed procedure is implemented in Matlab®, and the results show a satisfactory dynamic balancing.

摘要

In this paper, a new procedure for the dynamic balancing of a slider-crank mechanism is presented. First, the inertial properties are represented by equimomental systems of point masses. Then, the acceleration analysis is performed using natural coordinates, which allows us to obtain directly the acceleration of the point masses. The dynamic is solved using the screw theory through Davies’ method. Finally, the shaking screw is proposed, with which the objective function is formulated. The proposed procedure is implemented in Matlab®, and the results show a satisfactory dynamic balancing.
