유한요소해석을 이용한 조향장치 토크센서의 설계에 관한 연구

The oil-pressure type torque sensor has been adopted in steering system of major automobiles. However, it has been well known that this type of torque sensor needed many subcomponents and produced inaccurate responses. This paper intends to suggest new type of torque sensor based on the shape design by using finite element. A dedicated mesh generation, analysis and post result display program has been developed. As for shape design purpose, the half shape of torque sensor is considered. The result of this study has shown that the design automation for precise torque sensor for control of high velocity rotation shaft can be achieved whithout any expensive investment to the design software.
