AI Technical Summary

Technical Problem

Existing yaw brake test benches cannot meet the testing requirements of wind power yaw systems supported by sliding bearings, especially due to high manufacturing costs, short wear life of friction plates, and high operating noise.

Method used

A test bench for a wind turbine yaw sliding bearing system was designed, including components such as the fuselage, platform, slider, linear guide, drive cylinder, and loading cylinder. The test bench simulates the friction pair test between the gear ring and the sliding pad assembly through a hydraulic system and computer control. It supports the clamping adjustment and servo control of the disc spring on the brake caliper and records data such as friction force.

Benefits of technology

It enables precise testing of wind power yaw systems, can simulate actual working conditions, record key parameters, and supports remote operation and unattended operation, meeting the testing needs of new yaw systems.

Abstract

本发明公开了一种风电偏航滑动轴承系统试验台,用于风电偏航滑动轴承系统摩擦滑垫和制动钳的综合测试。测试部位的结构和尺寸与风电实际结构相同,以一个制动钳和对应的滑垫组为测试对象;以直线反复运动模拟齿圈与滑垫组构形成摩擦副;四个油缸用于垂直加载和横向 / 纵向的偏载加载;一个水平布置的油缸径向加载;模拟齿圈的往复运动和各油缸的加载力均由液压伺服控制,可实现按设定程序的运动和载荷谱测试,制动钳上的碟簧夹紧调整螺栓由专用的油缸代替,进而实现下滑垫夹紧比压的伺服调整和控制;在计算机控制下,可实时显示并记录摩擦力、摩擦系数、摩擦行程、垂直载荷、偏载、径向载荷、环境温度、试件温度、上滑垫磨损量等数据和曲线。
