Optimization of Comprehensive Performance of Planar Redundant Parallel Manipulator

  • Received Date: 11 Dec 2007

  • The optimization of comprehensive performance of a planar 2-DOF(degree-of-freedom) redundant parallel manipulator was investigated.Based on the kinematics model of the manipulator,its Jacobian matrix and optimal topologies were given.The influences of structural parameters of the manipulator on its workspace and singularity were discussed.A comprehensive performance criterion was proposed to evaluate kinematics accuracy,force transmissibility,structural stiffness and workspace utilization rate.An optimization model with the proposed criterion as the objective function and task-space and nonsingular configuration as the constrains was constructed,and an adaptive genetic algorithm was utilized to obtain the optimal solution.The research provides a reference for the optimal design of similar manipulators.
