With the development of manufacturing industry, the stroke speed of stamping machine is higher and higher. In accordance with the development, researchers and engineers have paid more and more attention to developing various types of ultra high speed stamping machines. The key to develop ultra high speed stamping machine is to solve the problem of inertia equilibrium. This paper presents an optimization approach for multi-objective inertia equilibrium design for ultra high speed stamping machine. Simulation results demonstrate the effectiveness of the proposed approach.
