[Abstract]:A new type of horizontal hydraulic press is designed according to the requirements of customers. The frame is composed of two beams and three pulling rods, and the position distribution of the three rods is asymmetrical to the action center of the hydraulic pressure. In order to solve the problem that the tension bar is not balanced due to the asymmetry of the position distribution of the rod, the optimization model of the frame of the asymmetrical horizontal hydraulic press is established, and a particle swarm optimization algorithm with decreasing inertia weight concave function is proposed. The program Matlab and ANSYS are used to solve the problem. The experimental results show that the proposed algorithm is more effective than the particle swarm optimization algorithm with decreasing inertial weight linearly. The weight of the frame is reduced by 13%, and the force between the rods is more balanced. The purpose of optimization design of asymmetric hydraulic press frame is achieved.
