摘要

提出了风力发电机组的耦合刚体系统的数学模型。用线性化的方法得到了静止运动的稳定条件。对于叶片偏差小、刚度系数大的情况，导出了由角速度和惯性参数组成的稳定条件。在附加约束条件下，得到了容许锋面压力的充分稳定性条件。证明了当轴的刚度系数足够大时，模型的均匀转动是稳定的。

Stability analysis of a wind engine model with elasticity

A mathematical model of a wind engine unit has been proposed as a system of coupled rigid bodies. Stability conditions of a stationary motion have been obtained by means of linearization. For the case of small blades deviation and large stiffness coefficients, we derive a stability condition in terms of the angular velocity and inertial parameters. Under additional constraints, we obtain a sufficient stability condition for admissible frontal pressure. It is proved that uniform rotation of the model is stable when the shaft's stiffness coefficient is large enough.
