Abstract
The high operating speeds of a linkage result in the shaking force/moment and the driving torque to change significantly. The balancing effects by the mass redistribution method or the counterweight method are not satisfactory sometimes. In this paper, we propose a new mixed mass redistribution method. The optimum dynamic design using the new method is investigated, based on genetic algorithms. The results of the counterweight method, the mass redistribution method and the new method are compared, and it is shown that the new method can reduce the shaking force/moment and the driving torque more effectively than the methods used previously. Moreover, it is also demonstrated that using genetic algorithms we can obtain optimum dynamic characteristics more efficiently than by the traditional nonlinear optimization techniques. The small element method is used to obtain the shape of links according to optimized linkage design parameters.
