| Wind power gear box is the core part of the wind turbine, because of the long-term impact of adverse environment, so prone to failure. To discover the potential danger of the gear box is necessary according to the generation of vibration with noise detection model. The present procedures of Silver Star energy Limited by Share Ltd measurement noise have a lot of disadvantages:not accurate, error. According to the company’s current noise detection model and using the software, learning about the use and the design and manufacture of a special equipment to replace the artificial measurement, through practice proved that, the device before it can well solve the problem.Tracking operation process of the enterprise’s whole loading test bench, understand the principle of the experimental platform and the function of each parts, noise testing process with1,2.5MW gear box. Establish working sketch of loading test bench. The factors affecting noise measurement is not accurate, find out the feasible methods to solve this problem. The main work includes:Position the work of Surveying and mapping state of gear box, the position mapping experiment platform of main parts, including the size of Surveying and mapping of sound intensity probe.Analysis on the composition and the principle of noise detection device.Draw the part drawing and assembly drawing by using MDS software, CAE software for modeling and Simulation of mechanical equipment. Which comprises a base, upright, motor and the choice of coupling.Modeling and Simulation of mechanical equipment in the CAE software, and complete the entity construction, field tests were carried out based on entity completed, feasibility is correlated noise data verification equipment. |
