The design of experiment (DOE) with orthogonal arrays is adopted when the engineering design is needed in a discrete design space. In this research, a design process with orthogonal array is performed to obtain the optimum design which satisfy the frequency target of the steering system. The optimum design is determined from the analysis of means (ANOH) and sensitivity information about design variables is evaluated by the analysis of variance (ANOVA). Interactions between design variables are investigated to achieve additivity which should be valid in using orthogonal array. It is shown that when strong interactions exist, the DOE process with orthogonal array considering interaction is introduced to find out optimum design .

Bellows is an important part to reduce a vehicle vibration due to exhaust system. The durability performance of bellows is dominated by many factors such as material property, shape of corrugation, total length of bellows, and length and height of pitch. In this paper, it is noted that the durability problem of bellows may be improved not only by the durability performance of itself, but also by considering the dynamic behavior of total exhaust system. The dynamic behavior of bellows due to road excitation is analyzed and a simplified methodology is introduced to improve the durability performance of bellows.

In this study, an optimization method of damping sheet treatment was developed to reduce the structure-borne noise below 500 [Hz]. As a method to optimize the damping sheet treatment, both the velocity distribution and the sum of strain energy distribution on panels are investigated and used to determine where the damping sheet is patched. The optimization procedure was proposed to find the optimum damping treatment developed in this paper consists of panel contribution analysis, the velocity distribution and the sum of strain energy distribution on panels. As a result of this study, either not only both the design weight and the cost of damping material have reduced, but also the structure-borne noise has improved.
