摘要：The structural vibration generated by building mounted small wind turbine was fully investigated by author. In order to achieve this, the real vibration condition of wind turbine in field was accurately simulated in Lab for research. There are some difficulty during the whole simulation process for further quantification of vibration levels. One of the main concerns was the correct estimation of the excitation or contact force at the interface between vibration source (turbine) and receiver (building or walls). However, the relevant simulation method in Lab is not available so far. In this paper, the direct measurement of force was investigated and found unsuitable. A new simulation method was proposed including solving the problem of power supply (DC electric motor used), automatic control of rotational speed of motor and indirect interface force determination. At last, the new established finite element models (FEM) was validated by experimental data with a good initial agreement.
