Abstract

This study was conducted to develop and verify a torque application device for use in a mechanical power-circulation test rig for 5.5 MW wind turbine gearboxes. The design and analysis of the torque application device was conducted. In addition, the torsional stiffness of the test rig was calculated using the rotational angle measurements for each of the components. The calculated stiffness of the test rig was $231.13kN{\cdot}m/rad$ for a clockwise torque application. The rated torque can be applied when the stiffness of the gearbox is greater than $1,064,400kN{\cdot}m/rad$ for a clockwise torque application. Because of the limited rotational angle of the test rig, the potential application of the rated torque is determined according to the torsional stiffness of the test gearbox.

본 연구는 5.5MW 증속기용 기계식 동력순환 시험 장비의 핵심 기능을 하는 토크 인가 장치의 개발 및 검증에 관한 것으로, 설계 및 해석이 수행되었다. 또한, 시험 장비의 각 부품에 대하여 회전각을 측정하여 비틀림 강성을 확인하였다. 시험체를 제외한 시험 장비에 토크를 인가하여 각 부품의 회전각을 측정한 결과 시험 장비의 비틀림 강성은 정방향에서 231.13 kNm/rad으로 나타났으며, 증속기 1대의 비틀림 강성이 1,064,400 kNm/rad보다 큰 경우 정격 토크를 인가할 수 있다. 따라서 시험 장비의 회전각 한계로 인하여 시험체 증속기의 비틀림 강성에 따라 정격 토크 인가 여부가 결정된다.
