ive one, and internal penalty function method is used for converting the constrained optimization into the unconstrained one. Then the geic algorithm is used for optimization of parallel mechanism. Elastic dynamics behavior of parallel mechanism after optimization based on the optimization results has improved apparently.Key words: Elastic dynamics, Sensitivity, Idealpoint method, Internal
