For the phenomenon of fast energy consumption and frequent battery replacement in the process of testing stress on the surface of the drum spoke by wireless stress sensor node. This peper designs the simulation experiment device to analog the operation condition of hoist drum. The simulation experiment device contains a simulation drum, a piezoelectric cantilever beam device, an energy harvesting circuit, wireless module, PC, etc. Finally, simulation experiments of wind-induced vibration energy collection are conducted. The experimental results show that the output voltage of the energy output circuit is 4.4 V, which can satisfy the normal power supply of wireless sensor nodes.
