With the rapid development of shipbuilding industry in our country, the demand for gantry crane for shipbuilding in each shipyard is expanding constantly, and it is becoming larger, lighter and faster. Automation and intelligence are growing rapidly. In view of the lag of crane design, how to improve the design level and design efficiency of gantry crane for shipbuilding is particularly important to enhance the competitiveness of enterprises. On the basis of modularization of shipbuilding gantry crane, this paper adopts object oriented thought, synthetically uses mixed reasoning mode, parameterized variant design, virtual prototyping technology.

The module planning model based on the module matrix is established. 2. The rapid customization design subsystem of shipbuilding gantry crane is established by using the idea of object oriented. The rule-based reasoning and case-based reasoning are alternately operated to cross-apply their information and results to form a preliminary design scheme, and based on the design knowledge of shipbuilding gantry cranes, the preliminary design scheme is automatically checked. The parametric variant design method of integral control is adopted, and the API function is developed twice by Solid Works, which realizes the automatic acquisition of interface parameters between parts and components. In view of the superiority of virtual prototype simulation, the evaluation subsystem of shipbuilding gantry crane prototype is established. The dynamic model of crane under different working conditions is studied. It provides the theoretical basis for ADAMS simulation analysis, based on the 3D solid model generated by rapid customization design, establishes the virtual prototype which can reflect the real working condition of shipbuilding gantry crane, and combines with ADAMS programming, The driving function and script simulation control function are added to simulate the various working conditions of shipbuilding gantry crane, and the corresponding curves of each condition are analyzed to evaluate the stability, static and dynamic characteristics of shipbuilding gantry crane, and verify the correctness of the design. From the perspective of integration, the system developed in this paper applies prototype evaluation and rapid customization design to shipbuilding gantry cranes to form a closed-loop design system. It has certain significance to improve the design level and design efficiency of shipbuilding gantry crane: rapid customization design system avoids repeated design and improves design efficiency, prototype evaluation system verifies the correctness and reasonableness of design; The combination of the evaluation result and the design process can lead the designer to modify the design in time, which can meet the needs of practical application.
