Analysis on influence of manufacturing error for output accuracy of hybrid five-bar mechanism
2008
A hybrid mechanism is a configuration that combines the motions of two characteristically different electric motors by means of a mechanism to produce programmable output. In this paper, by means of establishing mathematic model for the influence of output accuracy of a planar hybrid five-bar mechanism affected by manufacturing error of link length, the sensitive coefficient of manufacturing error of link-length was determined and the law of influence on output accuracy of hybrid mechanism affected by manufacturing error of link length was analyzed. Living example of design shows that reasonable designed manufacturing tolerance of link length of hybrid five-bar mechanism could make the mechanism not only satisfy the requirement of accuracy but also achieve lower manufacturing cost.
