| Summary: | 碩士 === 國立高雄海洋科技大學 === 輪機工程研究所 === 97 === This research focuses on the functional combinations between vertical axis wind turbine and magnet disk for reducing weigh systems. Such a construction is mainly composed by the two pieces of circular magnetic discs. Through the insertion of the upper disc with a circular permanent magnetism NdFeB, the fixation of both compartments could be achieved. The ironic lower disc would then be connected with the generator, blades, and framework of the vertical axis wind turbine. According to the law of magnetic suction, a force of attraction would be generated by both upper and lower discs. It is predicted that such an application can effectively reduce required spare parts, thus decreases the ponderousness of the turbine itself.
The main concerns of the article are as follows:
1. The comparison of the magnets and their force of the attraction of different models (operated under static simulation).
2. The graphic comparison of magnetic force curve under different rotational speed.
3. The comparison of the magnetic field intensity (H) and the magnetic flux density (B).
The experiments will be able to get the required data of the system, under which condition it reaches the maximum stability. The data not only help minimizing the vibration, but also reduce generated friction during high speed rotation of the vertical axis wind turbine.
