The anti-resonant vibration machine(ARVM) can effectively decrease the force to the base. Because the amplitude of down-body must be small and the multi-objective optimization of dynamical parameters is important to ARVM. According to the characteristic of ARVM, the list parameters aggregation genetic algorithm is presented. In this new genetic algorithm, the parameters obtained from one of optimal objective are listed, and the serial number of every parameter is coded, and the genetic algorithm is based on the coded serial number. At the same time, the improved crossover operation is used to enlarge the search space and increase the convergence rate The novel algorithm is applied to the optimization design of the ARVM, the results show that the algorithm is effective and practical.
