Abstract：According to the precise design requirement of eight-linkages mechanical press,a multi-objective function of minimum of the stroke design error and the working stroke drawing velocity fluctuation was established,which dynamics characteristics of mechanism as the constraint conditions.The NSGA-Ⅱ algorithm was used to optimize the mathematical model which contains 12 variables,and ensured that the minimum stroke design error was the first additional criterion,and the final system parameters are determined in the Pareto optimal solution.Optimization example shows that this method can provide reference for the rapid design of eight-linkages mechanical press.
