英文摘要:

      In order to solve the deficiencies in the function and form design of underwater intelligent search and rescue devices on the market, and the problems that the devices can not comprehensively deal with rescue in multi-shaped waters, the work aims to integrate Fuzzy Delphi Method (FDM), Fuzzy Analytic Hierarchy Process (FAHP) and Inventive Problem Solving Principle (TRIZ) in the innovative design of intelligent search and rescue device in waters. FDM was used to formulate and screen out the evaluation demand indexes of products. FAHP was applied to obtain fuzzy index weights and rank their importance, establish a target product level index model, and master the important entry points to be solved in the research and development process and solve the problem of water search and rescue through TRIZ theory Conflict problems. The design schemes were evaluated comprehensively to obtain the overall score of the water intelligent search and rescue device, and obtain the priority order of the design schemes. ANSYS-Fluent software was adopted to carry out numerical simulation of hydrodynamics for the preferred scheme, and verify whether it conformed to the fluid dynamic requirements. The combination of multiple methods can systematically carry out quantitative design and simulation inspection of products, which can reduce the subjectivity and uncertainty in the design process, make the design more objective, rational and accurate, and provide quantitative analysis reference for the research and development of related products.
