| 초록 |
The intermediate shaft assembly must be designed to satisfy the requirements for yield strength, ultimate strength, rotational durability and torsional durability. In the past, it was considered acceptable when the maximum stress did not exceed the yield strength under a torque of 200 Nm. Recently the standard has been strengthened to satisfy the yield strength requirement under a torque of 280 Nm. Under a torque of 280 Nm, the original design did not satisfy the yield strength requirement at the yoke of the shaft. The thickness of the yoke was increased from 7.7 mm to 9.1 mm to satisfy the yield strength requirement. Then efforts were made to reduce the thicknesses of shaft and tube where the maximum stress was relatively low in the original design. By reducing their thickness, the weight of intermediate shaft assembly was reduced by 8.14 % while all the four requirements were satisfied with the modified design. |
