【Abstract】 In this paper,the principle of infinitesimal linear transform is used in deriving a general methodfor calculating the accuracy of mechanism. Using this method, the accuracy can be computed simply aftermaking geometry analysis for the mechanism,establishing a coordinate system and determining the motionaltransform matrix and the error matrix. Thus it is unnecesary to establish input/output displacement equa-tions.更多还原
