Method for quickly configuring and designing large container crane

Abstract

The invention discloses a method for quickly configuring and designing a large container crane. The method comprises the following steps: building a large container crane product configuration framework for quick design; analyzing and calculating local similarity, local green characteristic satisfaction degree and cooperation affinity between a case template and customer requirements, and building a 0-1 genetic programming evolutionary model with constraint. In combination with the characteristic of large scale of configuration and optimization problem of the large container crane products, a pseudo-random proportion rule of an ant colony algorithm is redesigned; a candidate gene case number reducing rule is provided on account of the problem that the number of candidate gene cases is often more; an x-Sigmoid function is designed, and the transition probability is adjusted according to the function, so that the algorithm searching speed is increased; the predatory strategy is carried out, so that the development of optimum areas is enhanced, and the searching capability is improved; by comprehensively utilizing the model and the algorithm disclosed by the invention, a satisfactory preliminary design scheme of the large container crane is obtained in a short time; the flexibility is better.

Description

technical field [0001] The invention relates to the technical field of product configuration theory and method research, in particular to a large-scale container crane rapid configuration design method. Background technique [0002] Large-scale container crane is an evolutionary serialized and personalized complex mechanical product under the single-piece and small-batch production mode, and its design process has certain complexity. On the one hand, the conditions of each container terminal, the type of ship being loaded and unloaded, the water depth, and hydrological conditions will all lead to the diversification of large container cranes. For example, the reach, lifting height, and lifting capacity of large container cranes are different, depending on the type of ship being loaded and unloaded; the maximum wheel pressure and wheel base of the crane are different, depending on the geological conditions of the wharf, allowable wheel pressure, etc. In fact, the container c...

Problems solved by technology

The analogy design and empirical design methods mainly used at present fail to make scientific use of product historical design information, and there is a lot of duplication of labor and huge waste of resources
