It is essential to study the vibration phenomena caused by various faults in the wind turbine generator and to predict the faults in advance.
The WTS-3000 is identical to wind turbine operation, but it is designed to operate as a servomotor instead of a blade, so it reproduces the fault of the windturbine safely in the laboratory. The engineer in charge of diagnostic work can learn the cause of vibration and measurement method, and can use it to cultivate the ability to find a solution to the vibration.

Detailed Description

It is very difficult to find mechanical faults with vibration monitoring in low speed machines such as wind turbines. The WTS-3000 is designed to reproduce faults in low-speed machines and teach users how to detect and analyze them. You can learn how to detect gear failure at high speeds such as planetary gear defects as well as the detection of bearing defects at low speeds with a single simulator. For the conventional simulator several types of defective parts were prepared separately, and normal parts should be replaced in order to reproduce faulty signal. In this case, the mechanical condition (boundary condition) changes due to disassembly and reassembly, so it was difficult to grasp only the vibration phenomena caused by defects. This product is designed to replace normal parts and defective parts with simple sliding because normal parts and defective parts are assembled together. It is possible to eliminate the phenomenon that the condition of the system is changed  due to reassembly after dismantling and reproduce only the vibration signal due to the defect.

In particular, since the normal gear and abnormal gear are assembled together in one box, these faulty and normal gear can be easily replaced and tested.
