摘　　要：G58-850风电机组在实际运行过程中,刹车盘极易产生裂纹,造成多台机组停转,影响整套制动系统的正常运行。本文从几何外形、应力分布等方面分析了风电机组刹车盘上裂纹产生的原因,并提出了从改善金相组织、化学成分及热处理工艺等方面降低裂纹产生的方法。The brake disc is easy to crack during G58-850 wind turbine processing, which can make many units stop and affect the normal operation of the whole brake system. This paper analyses the cause of wind turbine brake disc crack, such as geometric shape and stress distribution. Some methods for reducing the crack are put forward, such as improving microstructure, chemical composition and heat treatment processing.
