초록

Automotive industry requires high technologies to stabilize apparatuses for the EGR valve manufacturing. Vibrations of washing machine are one of the most critical factors for causing unwashed products, which are the main reasons of the defects.In this study, the structure of the washing machine was analyzed through the experiment and the computer simulation to investigate the main reasons of the vibrations, and further to alter the design for the improved stability. And the design alterations were applied to the machine to identify the effects of those alterations.The result of the study shows that design alterations of the washing machine can effectively suppress about 85% of the vibrations, and further can minimize the unwashed EGR valve.
