Development of Cost Saing and Sloshing Noise Reductive Baffles of Fuel Tant Using Triz and Taguchi Engineering Method

Kim, Yunseok / Jeong, ChiWeon / Lee, MinSup / Yoo, JaeGon

Since the movement of fuel by the force of inertia in tank always generates crashes to the wall of tank inside or surface wave motion of fuel, noise and vibration problems are easily observed under the condition of vehicle acceleration, deceleration or the stand still. In order to solve this problem, optimization of tank form, addition of damping pad to the structure, and baffle plate to the tank interior have been tried currently. This paper suggests a new concept development of cost effective device and optimization of the design. We have applied Triz and Taguchi method among Design For Six Sigma to approach this problem to achieve noise and cost reduction at the same time. In addition to that, the steps for solving this problem and the design guide of new concept including new sound quality index will be suggested.
