Reduction of vibration by optimum balancing of shaking force/moment in linkage

We propose a relationship between the response of a forced vibration model having six degrees of freedom for any planar unbalanced linkage and its exc itation caused by the shaking force/moment of a linkage. We also present a criterion which expresses the compromised value of response in terms of cou nterweight mass parameters used as an objective function In optimum balanci ng. The effects on shaking force/moment and on vibration response predicted by using the new criterion are compared with those obtained by a classical method. Results show that the vibration response of the system predicted b y the new approach is much smaller than that obtained br the classical meth od. The measured responses of the system at three points also show that the new method is effective in reducing vibration response.
