  • 본 연구에서는 다구찌기법을 이용하여 소음원을 규명하고 생산성의 저하없이 사용자의 어떤 사용조건하에서도 일관된 저소음의 성능 특성을 발휘할 수 있도록 소음에 대해 강건성과 안정성을 갖는 설계인자를 규명하였다. 설계인자의 소음에 대한 기여도를 파악하여 파라메터설계, 이동보도와 같은 다른 유형의 시스템에도 적용할 수 있는 범용성과 차세대 에스컬레이터에 대한 선행성을 확보하였다.

  • Manufacturing process of plugs is firstly performed in the making of FRP yacht so it is an essential process for making original form. In the developed countries, it has been useful to manufacture structures of streamlined forms or complex forms, which have been difficult to manufacture due to limits of the traditional hand-made technology, by introducing 5-axis machining technology. In this study, the factors that affect most in the machining were found by using Taguchi Method in order to select the optimized machining conditions for 5-axis machines, and the ways to improve the surface roughness of machined products by applying those factors.

  • In this paper, an efficient robust design utilizing an enhanced Taguchi method is proposed to reduce cogging torque of a BLDC motor in the presence of design uncertainty. To overcome defects of the conventional Taguchi method in dealing with a generalized robust design problem, a penalty function and an optimal level searching technique are newly introduced. In order to verify the proposed method, a 5 kW, rated speed of 2,300 rpm, rated torque of 20 Nm BLDC motor for driving electric vehicles is optimized. Then, the robust design is compared with conceptual and deterministic ones in terms of the cogging torque, rated torque and torque ripple.

  • The Taguchi method is applied to obtain the optimal design of an automotive pedal arm in consideration of the stiffness test specification. Design parameters are defined to describe shape of the pedal arm. Volume, maximum Von-Mises stress and maximum displacement of the pedal arm are established as the smaller-the-better characteristics. Optimal parameters are determined on the basis of the analyzed level averages of the characteristics.

  • The specific noise level of 18 rotary compressor mufflers were measured and these data were analyzed by the Taguchi robust design method and the neural network. The optimal design value obtained by the neural network generally showed good agreement with that by the Taguchi method. The effects of eight important design variables on the specific noise level were discussed.

  • 본 논문에서는 무인 생산 공정의 선삭 가공 시 발행하는 칩의 처리에 관한 연구를 수행하였다. 선삭시 발생되는 칩은 부품의 정밀도와 표면 조도를 저하시키는 등 품질 저하와 함께 생산성을 저해하는 요소가 되기도 한다. 이러한 칩을, 칩 브레이커를 사용하여 작은 곡률 반경으로 절단함으로써 칩 제거를 효율적으로 제어한다. 그와 함께, 다구찌 기법을 적용하여 최적의 조건으로 칩 브레이커 형상 설계 인자를 도출하는데 그 목적이 있다.

  • In this paper, the optimized design of a rectangular O-ring groove has been analyzed for a maximum Cauchy stress and maximum strain using the Taguchi method. This method may efficiently optimize the design parameters for an O-ring groove of a LPG filling unit. The computed FEM results indicate that the optimized design parameters can only be drawn by nine experimental numbers of iterations when the Taguchi design technique has been employed with a finite element method. This means that the Taguchi design method is very useful for the optimization design of O-ring rectangular groove geometry. Based on the computed FEM results by the Taguchi design technique, the dimensions of a groove geometry are given as h=2.5 mm, d=2.74 mm, c=0.15 mm, and w=3.0 mm. In this study, the initial compression ratio of O-rings is recommended as 8.7% for a gas supply pressure of 18 $kg/cm^2$.
