A novel 3-DOF translational compliant mechanism based on flexure hinges is designed, analyzed and simulated in this paper. The mechanism is completely decoupled in XY directions, while there is a very small parasitic motion in Z direction when the XY axes are driven due to the lack of symmetry in Z direction. The pseudo-rigid-body model (PRBM) of the mechanism is established to analyze the relationship...
This paper presents a straightforward and systematical methodology for conducting the inverse dynamic analysis of a 3-prismatic-universal-universal (PUU) parallel kinematic manipulator (PKM) through employing the principle of virtual work. The proposed 3-PUU PKM possesses three translational degree-of-freedom (DOF). The position, velocity and acceleration of joints are solved via the inverse kinematic...
In recent years, many applications in precision engineering require a careful isolation of the instrument from the vibration sources by adopting active vibration isolation system to achieve a very low remaining vibration level especially for the very low frequency under 10 Hz vibration signals. In this paper, based on our previous research experiences in the systematical modeling and study of parallel...
The kinematic design of a medical parallel manipulator used for chest compressions in the process of cardiopulmonary resuscitation (CPR) is presented in this paper. According to the requirements of CPR action from medical viewpoints, a 3-PRS (prismatic-revolute-spherical) parallel manipulator (PM) is designed utilizing an architectural optimization methodology for such applications. The dynamic modeling...
