초록

Brackets for an automatic transmission are usually used to connect the transmission with adjacent components in a vehicle. Fillet areas of brackets are one of the most important areas to design the brackets because the areas are easily fractured when the brackets are subjected to external loads. In this study, a new design around the fillet area of the bracket is suggested and improved effects of the proposed design are proved through the comparison of safety factors with the current design. The safety factors are calculated through the fatigue analysis via a commercial code, FEMFAT.
