Two-Objective Optimization of Drawing Mechanism Based on Genetic Algorithm

Abstract:

Multi-bar linkage mechanism is one of the most important directions to the development of mechanical presses. But there are a large number of bars, so how to choose each bar size to ensure the best kinematical characteristic and to achieve longer drawing depth as soon as possible is a key to the design. This paper established kinematics mode of the eight-bar drawing mechanism by bar-group method, and deduced kinetics expressions of all bars, then developed application simulated system by Visual Basic, characterizing Windows universal interface. In addition, proposed two-objective optimization functions-drawing depth and drawing speed, and optimized the mechanism by genetic algorithm. The optimization results shows that its motion performance has been improved in a great degree.
