초록

The objective of this study is to investigate the effect of tubular shaft hole length on the A-IMS production process in numerically. The hole length of tubular shaft was changed from 69.5mm to 79.5mm for distribution of load and stress. Then, the tubular shaft was modeled by S20C which was referred to program library. At the same time, the results of numerical analysis were compared in terms of under-fill, metal flow, principal stress, Von-mises stress and load characteristics. In the results, the load and stress were increased at 4 stage when the hole length of tubular shaft was increased. Also, folding phenomenon was observed to intensify as increasing the hole length of tubular shaft by confirmation of metal flow.
