Research On Intelligent Design Of Hoisting Mechanism Of Bridge Crane&Gantry Crane

Crane is a kind of special lifting equipment which working at places such as power plant, workshop, shipyards, mines and other places. Along with all walks of the expanding demand for crane expanding, crane industry in China is highly competitive and rapid development. And the way of crane design is towards to customize, digitization, large and light weight development rapidly. Given the low efficiency of traditional design method of crane, thus increasing design efficiency of cranes, also raises the crane manufacturer’s competitiveness.Regarding the automation of bridge&gantry Crane parts selection in traditional design methods is Inefficient. Based on a domain ontology knowledge of crane parts, An ontology-based intelligent rapid design system of bridge crane parts was established, using hybrid reasoning mechanism, parametric variant design.Main contents of the paper are as follows:1. Analysed of the lifting mechanism composition and work principle,and the design and calculation method of lifting mechanism.2. Combined with the basic principle of intelligent design for crane lifting mechanism underlying library of intelligent design system design, process design and framework design.3. Build a domain ontology knowledge of bridge crane parts with Protege software and reasoning machine is used to check the domain ontology consistency. In accordance with the relevant principles of inference rules for matching library. Build bridge crane parts model library. Then unifies all the parts together based on the VS-2008platform.From the point view of integration, the system developed in this paper used the ontology and parameterized design in bridge&gantry crane, and form a closed loop, an ontology-based Intelligent and rapid design system of crane parts which avoided duplication of design, and improved design efficiency. Improve the design level and design efficiency of the crane to some extent.
