다구찌법을 이용한 파이프 피팅 설계

A pipe fitting device used in hydraulic oil industry, shipbuilding, petrochemical, power plants, industrial plants and semiconductor industry is a mechanism that controls the flow of fluid. A pipe fitting device is separated by forging and welding, and general fitting. Device material, size, environment and stop leak is dependent on type of fitting method. In this paper, was designed to pipe fitting device using plastic deformation between pipe fitting link and pipe by applying external pressure on links. Design of Pipe fitting device using finite element analysis and Taguchi method. Design parameters were optimized in range.
