Abstract: A fluid-induced vibration energy harvesting apparatus with a non-rotating bluff body is provided. The apparatus does not use a common design method of rigidly securing a bluff body to an elastic beam in a design of the bluff body, but adopts a manner of connecting the bluff body and the elastic beam through a rotating shaft and a connecting shaft. Because a kinematic pair at a connection position is a rotating pair, the bluff body will only vibrate transversely and will not rotate, thereby achieving an effect of increasing an amplitude at the same frequency, and finally realizing an increase of converted electric energy and improving the conversion efficiency.
