NO.1
Take a piece of shredded paper and let it fall freely in a windy area. By measuring time and horizontal displacement, you can approximately know the wind speed. aerodynamic force and fluid equation of shredded paper, it's definitely not precise, just approximate.
NO.2
Stand at the window and spit down below. Remember to spit in a straight line towards the money. Unless your mouth is crooked, you can do it. the pin The location of the drop. Count silently in your mind. The time it took to fall. This is the wind speed.
In fact, every manufacturer of wind power generation equipment has vibration sensors, but the location. and the number are different. But they will not be placed on the cabin, but on the main cabin equipment. (Maybe my understanding is ambiguous)
Take the example of MM82 resetialized. There are two sensors to measure vibration, one is under the generator and the host vibration analyzer on the main frame. Another vibration analyzer on the elastic support of the gearbox.
They are all installed on the main device.
Let me say a few more words. The main shaft, gearbox and generator are all in the transmission system of the wind turbine. Therefore, in principle, it is effective to install vibration equipment at any position. but the safety of the wind turbine must be taken into account. The operating angle is more effective when installed on high-speed transmission parts.
I hope this helps!
