摘要
针对双滚筒采煤机镐形截齿的失效问题,首先分析了该种截齿的结构和常见失效形式,然后对截齿的受力组成进行了研究,在此基础上,利用ABAQUS有限元软件,分别对正常工况、钎焊松动工况和齿体磨损工况下的截齿应力特点和失效机理进行了研究,并提出了相应的截齿结构优化建议。
In view of the failure problem of pick-shaped picks of double drum shearer, firstly analyzes the structure and common failure form of the picks, and then studies the force composition of the picks. On this basis, the ABAQUS finite element software, the stress characteristics and failure mechanism of the cuttings under normal working condition, brazing loose condition and tooth wear condition are studied respectively, and the corresponding suggestions are put forward.
