By adopting a continuation approach, the position analyses of a novel 3-5R parallel mechanism, which has three translation degrees of freedom, are conducted. Next, an equation system of the mechanism structure constraint and an initial equation system are established. Next, a versatile software for solving polynomial equation system is compiled. As giving(More)
Based on 3-RRRRR parallel mechanism, a novel 3-DOF micromanipulator which is driven by piezoelectric actuators has been put forward. From the aspect of micromanipulator, spatial parallel mechanism possesses the advantages of high stiffness, compact structure and so on, and overcomes the disadvantage of small workspace. All the flexible hinges of the 3-RRRRR(More)
By projective geometry theory, the dependency of screw system, which is constituted by three line vectors and three couples, or four line vectors and two couples, or five line vectors and one couples, is discussed. The lines in the P<sup>3</sup> will be mapped to the points in the P<sup>5</sup> by using the Klein mapping representation and the homogeneous(More)
