Large number of bolted structures exist in wind turbine equipment, once the bolt hole is defective, it may lead to fracture of the entire matrix and cause major accident, but the current bolt hole defect detection method has the situation of missed detection and misjudgment. Aiming at solving this problem, through investigation, theoretical analysis and physical research, two methods which combine special tooling with probe for bolt hole defect detection are developed, namely the direct beam method and the sector scanning deflection method. Taking the bolt hole of pitch bearing in wind turbine as the research object, the CIVA software is used to simulate the two detection methods, and the rectangular simulated crack can be detected. Experiments were carried out on the defects of rectangular grooves in the actual pitch bearing bolt holes, which showed that the direct beam method could realize the defect detection of bolt hole cracks. The research provides a new method for monitoring the service status of bolt holes, which is beneficial to ensure the safe service of bolted structures.

风机装备中存在大量螺栓连接结构,螺栓孔一旦出现缺陷,可能导致整个基体断裂,造成重大事故,但目前螺栓孔缺陷检测方法存在漏检和误判的情况。针对该问题,经过调研、理论分析和实物研究,研制出专用工装与探头结合的直射法、扇扫描偏转法2种螺栓孔缺陷检测方法。以风机变桨轴承螺栓孔为研究对象,采用CIVA软件对2种检测方法进行模拟,可检测出矩形模拟裂纹。采用实际变桨轴承螺栓孔加工矩形槽缺陷进行试验,结果表明直射法可实现对螺栓孔裂纹的缺陷检测。研究为螺栓孔的服役状态监控提出了新的方法,有利于保证螺栓连接结构的安全服役。

风机装备中存在大量螺栓连接结构,螺栓孔一旦出现缺陷,可能导致整个基体断裂,造成重大事故,但目前螺栓孔缺陷检测方法存在漏检和误判的情况。针对该问题,经过调研、理论分析和实物研究,研制出专用工装与探头结合的直射法、扇扫描偏转法2种螺栓孔缺陷检测方法。以风机变桨轴承螺栓孔为研究对象,采用CIVA软件对2种检测方法进行模拟,可检测出矩形模拟裂纹。采用实际变桨轴承螺栓孔加工矩形槽缺陷进行试验,结果表明直射法可实现对螺栓孔裂纹的缺陷检测。研究为螺栓孔的服役状态监控提出了新的方法,有利于保证螺栓连接结构的安全服役。

Large number of bolted structures exist in wind turbine equipment, once the bolt hole is defective, it may lead to fracture of the entire matrix and cause major accident, but the current bolt hole defect detection method has the situation of missed detection and misjudgment. Aiming at solving this problem, through investigation, theoretical analysis and physical research, two methods which combine special tooling with probe for bolt hole defect detection are developed, namely the direct beam method and the sector scanning deflection method. Taking the bolt hole of pitch bearing in wind turbine as the research object, the CIVA software is used to simulate the two detection methods, and the rectangular simulated crack can be detected. Experiments were carried out on the defects of rectangular grooves in the actual pitch bearing bolt holes, which showed that the direct beam method could realize the defect detection of bolt hole cracks. The research provides a new method for monitoring the service status of bolt holes, which is beneficial to ensure the safe service of bolted structures.
