摘　　要：[目的]风电偏航制动系统具有低压偏航和高压重载的应用工况,摩擦副之间的摩擦性能受到机组偏航制动部件之间各参数影响。[方法]基于盘式制动器的拖磨试验台,模拟风机不同工况下制动器运行情况,研究了不同材料对偶件、同种对偶件材料不同压力、速度和温度下的有机复合材料摩擦特性,并从摩擦学角度揭示了不同参数对摩擦系数的影响因素。[结果]结果表明:在同等表面参数下,不同对偶件材料对摩擦系数有较大影响;在同种对偶件材料情况下,制动压力和摩擦副相对运动速度越大摩擦系数越小,且制动压力对摩擦系数影响因子更大;摩擦系数受温度影响较大,摩擦副之间温度越高摩擦系数往往越小。[结论]此研究为风机偏航制动系统的参数选用及制动控制逻辑提供了重要参考思路和依据。[Objective]The wind turbine generator(WTG)yaw braking system has application in low-pressure yaw and high-pressure heavy load,and the friction performance between friction pairs is influenced by various parameters between the components of the yaw braking system.[Method]Based on the friction test bench of disc brakes,this paper simulated the operation of the brakes under different working conditions of the WTG,studied the friction characteristics of organic composite materials under different pressures,velocities and temperatures for dual components of same and different materials,and revealed the influencing factors of different parameters on friction coefficient from the perspective of tribology.[Result]The results show that under the same surface parameters,different dual component materials have a significant impact on the friction coefficient;The friction coefficient decreases with the increase of braking pressure and relative velocity of the friction pair and the braking pressure has a greater impact factor on the friction coefficient;The friction coefficient is greatly affected by temperature,and the higher the temperature between the friction pairs,the smaller the friction coefficient.[Conclusion]The research results have important theoretical significance and practical value for the parameter selection and braking control logic of the wind turbine generator yaw braking system.
