[Abstract]:At present, the market competition of marine engineering equipment is increasing day by day, the demand of users is changing rapidly, at the same time, its function and structure are becoming more and more complex, the traditional design technology has been difficult to adapt to the change of modern marine engineering equipment. In order to solve this problem, a digital design system of ocean engineering winch is constructed, which includes the functions of product digitization design, simulation analysis, optimization design and so on. In order to shorten the research and development cycle, reduce R & D funding, reduce development risks, to ensure the design of a reasonable purpose. The main research contents are as follows: firstly, based on the deep research of digital design theory and CAD / CAE system integration technology, the CAD / CAE system is integrated and developed by VC to realize the data exchange between CAD / CAE systems, thus improving the efficiency of product development. To ensure the accuracy of data transmission, as a basis for the subsequent construction of new product development and design. Secondly, on the basis of deeply studying the working mechanism, main structure and design theory of the winch, the information model, constraint network and its geometric model of the key parts are established in combination with the parametric modeling technology. A parameterized design system which can realize the design and modeling of standard parts, custom-made parts and serialized components of marine winch is constructed, which can achieve the purpose of rapid design and automatic modeling. At the same time, based on the digital model of marine engineering winch, the product digitization simulation analysis and optimization design are realized. The concrete work takes the reel part of the marine engineering winch and the belt brake part as the object, carries on the statics analysis to ensure that under the rated working condition, the reel part and the belt brake part can work safely; in addition, The optimum design of the dimension parameters of the reel is carried out to make the whole weight of the reel the lightest on the premise of ensuring the limit of the strength of the reel so as to save the material and reduce the cost. Finally, combining the software system development process of waterfall model, using CAD / CAE system integration technology, the design system of marine engineering winch is developed, which includes the function modules of product digitization design, finite element analysis and optimization design. The actual operation of the enterprise shows that it has remarkable effect on shortening the design cycle and improving the design quality. Based on the idea of digital design of mechanical products, this paper starts with the digital modeling of products, and constructs a "digital design system for marine engineering winch", which is centered on the rapid establishment of product models, including finite element analysis and optimization design and other functional modules. Good application results have been obtained, and its development ideas, theories and methods can provide useful reference for the development of other similar digital design systems for marine engineering equipment.
