...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...

... thoroughly analyzed in Ref. [ 2 ]. remote center-of-motion mechanisms type synthesis kinematics intersecting planes bifurcation If a part of a mechanism is restrained to rotate about a point not physically belonging to it, the mechanism is called a remote center-of-motion (RCM) mechanism...

... presents some significant phenomena as bifurcation, chaos, tooth separation and occurrence of multijump. An insight into the dynamic responses of the face gear drive system is made, some observations are instructive and meaningful to the design and the choice of work condition of face gear. The results...

...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...
