...Chen Zhao; Ziming Chen; Yanwen Li; Zhen Huang In this paper, a novel 3-UPU (P and U stand for prismatic and universal joints, respectively) parallel mechanism (PM) and its variant PM are proposed. Both of them have two rotational and one translational (2R1T) degrees of freedom (DOFs) without...

... the reconfigurable limbs. The paper further presents a mobility-change condition to construct a metamorphic mechanism with the reconfigurable limbs. This gives a family of metamorphic parallel mechanisms that have the facility to change mobility in the range of 3– 6. A further family of metamorphic parallel...

... parallel mechanism The sources of mechanism vibration, while varied and sometimes elusive, are most often ascribed to a combination of structural elasticity and poor stability properties of the control algorithm. In an illuminating experimental study ( 1 ), it has been found that for typical...

...Xianwen Kong; Clément M. Gosselin; Pierre-Luc Richard There are usually several motion patterns having the same degrees of freedom (DOF). For example, planar motion, spherical motion, and spatial translation are motion patterns with 3 DOF. An f -DOF parallel mechanism with multiple operation modes...

.... For such an N -DoF ( N < 6 ) mechanism, this method can build a square ( N × N ) Jacobian matrix and cubic ( N × N × N ) Hessian matrix. The formulas in this method for different parallel mechanisms have unified forms and consequently the method is convenient for programming. The more complicated...
