摘要：

Four-bar luffing mechanism was optimized to reduce manufacturing cost and operating cost of portal crane. An optimal design model with key parameters as design variables was established, And an optimization method based on genetic algorithm and finite element analysis was proposed, to minimize the weight, the unbalanced moment and the vertical drop of the cargo during the luffing process, while accomplish the technical parameters of portal crane. The parameterized finite element model generator was developed for four-bar luffing mechanism of portal crane. The performance constraint conditions obtained from finite element solver and the boundary constraint conditions were used to evaluate the optimal targets. The results indicate that the model and method is suitable for the structure and performance optimal design of the four-bar luffing mechanism of portal crane, and can improve the design quality effectively. ©, 2015, Zhejiang University.
