The effects of the inertia parameters of moving platform on the dynamic response
dynamic stress and natural frequency of flexible parallel mechanisms were studied. The mechanism total mass function is combined with elastic deformation energy function by using linear weighted method to derive the multiple objective function
and the boundary condition of inertia parameters
motion errors
natural frequency
dynamic stresses and driving moments are considered as constraint equations to perform the optimal design. The optimal inertia parameters of moving platform are determined based on the optimal design. The effects of the inertia parameters are well illustrated through the numerical simulation of a planar 3- R RR parallel mechanism. The inertia parameters of moving platform are demonstrated to have significant impact on the dynamic response
dynamic stress and natural frequency of flexible parallel mechanisms
and they should be important parameters for the analysis and design of the flexible parallel mechanisms.
