Development and Application of Parallel Mechanism

This paper introduces the development of the parallel mechanism at home and abroad,shows the features of the parallel mechanism and application in various fields by comparison with the serial mechanism.The working principle of the six-bar parallel mechanism was provided as a special form of the parallel mechanisms,and the features were explained by combining with the six-bar parallel mechanism used in the soft X-ray spectromicroscopy beamline of the third generation synchrotron radiation facility in Shanghai.
