| Abstract: | We present comprehensive research of a 2-DOF planar parallel mechanism to be used in a new type hybrid machine tool.The paper introduced this mechanism's composition,induced its kinematics direct and inverse solution formulas,and obtained the velocity Jacobian matrix.Taking the reciprocal value of the Jacobian matrix's condition number as the standard of dexterity and adopting the comprehensive assessment method in the whole space,the parameters of this mechanism were optimized using a genetic algorithm.Num... |
