摘　　要：建立变桨执行机构的三维实体模型,根据其运行原理模拟出其运动状态并分析其运动性能。基于风力机组的工作条件及变桨控制原理,搭建SIMULINK变桨控制系统模型,并结合UG运动协同仿真模块完成其控制系统的联合仿真和数据分析。相关的试验数据表明:该变桨执行机构在控制系统的控制下运动性能稳定且反应迅速,达到在变风速下稳定吸收风能的目的,能有效满足使用要求,为其进一步设计和控制优化奠定基础,同时提供了一种模拟机构工作运行性能的方法。A three-dimensional solid model of hydraulic pitch mechanism is established, movement of the pitch-regulated mechanism is simulated according to the operating principle, and its performance is analyzed. A pitch control system model of Simulink is set up based on working conditions and pitch control principle, its simulation is carried out combining with UG module, and data is analyzed. The relevant experimental data indicates that movement control performance of the hydraulic pitch mecha- nism is stable and has quick response, achieves the goal of stably absorbing wind energy under variable wind speed, and satisfies user＇s requirements, which could lay a foundation for further design and control system optimizing, and provide a method to simulate performance of some mechanism.
