Characteristics of low jitter kinematic for megawatt wind power yaw system
摘要
Abstract
Aimed at the low jitter phenomenon for yaw motion, a novel low jitter kinematic model of yaw system in the megawatt wind power was put forward by using the method of mechanism modeling, and its corresponding solutions were gotten. The results show that some factors such as torsional stiffness, yaw drive speed, friction coefficient difference, damping ratio and pressure are the major leading causes of low jitter for yaw system in the megawatt wind power. And it is conducive to the elimination of low jitter phenomenon, and yaw motion is caused by some factors such as the higher stiffness, suitable driving speed which is not less than the critical velocity, reasonable friction coefficient difference, higher damping ratio and smaller tightening.关键词
