“…An analysis of the expressions (12), ( 13), ( 14) and (15) shows that the rotor supports are solicited by periodic aerodynamic strengths, which generate vibration effects with the same frequency of that of the aerodynamic strengths. For a given regime, we record that the rotor support efforts are shared out between C and D in function of geometrical parameters defined by the machine dimensions ratios ) and also in function of the braking and aerodynamic forces.…”

“…Several wind machine configurations, including: i. drag-type turbines; ii-Lift-type turbine; appear during the design and simulation of rotating equipment, especially when this equipment is in contact with a given fluid. Among these equipment's the wind turbine represents a device which can utilize the wind's kinetic energy to produce the mechanical or electrical energy [15][16][17][18]. The vertical axis wind rotor as another important kind wind turbine is a good choice for men average and small-scale wind power generation [19].…”

The use of wind turbines for small-scale and urban applications is a topic that is receiving increasing attention. The use of wind turbines for small-scale and urban applications is a topic that is receiving increasing attention. This work concerns the Savonius rotor. It is divided into three parts. The first one consists in an original experiment which has led to the direct measurement of the pressure field on the blades of a rotating Savonius rotor. In the second part, the results are introduced in a generalized model to calculate the efforts which generate the vibrations at the rotor supports. This study explains well the vibratory behaviour of the rotor. Finally, in a third part an experiment analysis of an adequate system of a suspension to stabilise or avoid these vibrations is proposed. This study explains clearly the vibratory behaviour of the rotor.
