...Jun Wei; Jian S. Dai This paper investigates novel reconfigurable parallel mechanisms with bifurcation between planar subgroup SE(2) and rotation subgroup SO(3) based on a transformation configuration space. Having recollected necessary theoretical fundamentals with regard to compositional...

..., and the end-effector motion is confined to the plane F , as shown in Fig. 12( b ) . Fig. 12 The bifurcated motion of the mechanism when β = 45 deg Case (1): ψ 1 = 0 means that the plane E will not move while the two active joints are moving...

... response of the face gear drive system is analyzed with the numerical method, where the mesh stiffness is expressed in two patterns as time-varying form and time-invariant form. According to the comparative study, some significant phenomena as bifurcation, chaos, tooth separation and occurrence...

...Yu-Xin Wang; Yu-Tong Li In this paper, the disturbed configuration bifurcation characteristics of Gough–Stewart parallel manipulators at singular points are investigated. At first, the expended equation corresponding with the kinematics equation of the manipulator is introduced for eliminating...

...Yu-Xin Wang; Yi-Ming Wang The configuration bifurcations of Stewart parallel manipulators at singular positions induce the uncertainty of the moving trends of the manipulative platform. The Jacobian matrix method can determine the singular position of Stewart manipulators, but it cannot determine...
