Digital Mock-up to Optimize the Assembly of a Ship Fuel System
نویسندگان
چکیده
Assembly activities represent a crucial phase of new product development processes. The identification of potential assembly issues early in the design stage can thus allow companies to save time and cost of successive manufacturing phases. In such context, this article analyses the potential of digital mock-up (DMU) to enhance assembly feasibility and efficiency through specific design analysis. In particular, it is here showed the development of a DMU process and its integration with design for assembly (DFA) procedures at a large Italian company. The article illustrates the application to a ship fuel system and discusses the main benefits achieved by the company in terms of reduced assembly time, re-works, number of special tools used and incorrect assemblies.

Tehran Research Reactor (T.R.R.) is a pool-type, 5 MW thermal research reactor. One probable event is that if some external objects or debris fall down into the reactor core and cause obstruction of the coolant flow through one of the fuel assemblies, decreasing the surface flow area, ceases the coolant flow, and also raises the fuel and sheaths tempe...
متن کاملCharacterizing Flow-Induced Vibrations of Fuel Assemblies for Future Liquid Metal Cooled Nuclear Reactors Using Quasi-Distributed Fibre-Optic Sensors
Excessive vibration of nuclear reactor components, such as the heat exchanger or the fuel assembly should be avoided as these can compromise the lifetime of these components and potentially lead to safety hazards. This issue is particularly relevant to new reactor designs that use liquid metal coolants. However, identifying adequate sensors or techniques that can be successfully applied to reco...
