Description
Summary:According to the kinematics analysis of 4-RRCR spatial parallel mechanism with three rotation and translation(3R1T), establish differential Jacobian matrix relationship with input and output of four degree of freedom(DOF) spatial parallel mechanism, and used to design space of 3R1T full compliance mechanism. In the design, the method of solving the model of by method of Isotropic Material with Penalization(SIMP) is optimality criteria (OC) method. Through static simulation analysis, the compliance mechanism of obtained by flexible hinge replacement method and by the topology optimization method are respectively in HyperWorks®. The simulation analysis results show us the 3R1T full compliance mechanism design by topology optimization method has same motion characteristics as the traditional parallel mechanism, and the compliance mechanism design by topology optimization method global stiffness and material utilization are better than the compliance design by flexible hinge replacement method.
