摘要

摘要: 结合某型号采煤机导向滑靴实际工况，基于ANSYS对采煤机导向滑靴进行了静强度、疲劳及模态分析，分析结果表明：采煤机截割阻力和牵引力不在一条直线上，致使导向滑靴受到严重的轴向力，这是造成导向滑靴破坏的主要原因；导向滑靴的最大应力为200 MPa左右，为许用应力的70%；导向滑靴最薄弱的部位位于销轴孔下边；利用ANSYS软件中的模态分析模块，得到导向滑靴在正常截割煤壁过程中的固有频率和振型。该分析结果可为采煤机导向滑靴的优化设计提供理论指导。

Abstract: Static strength, fatigue and modal analysis of guided sliding boots of shearer were done based on ANSYS combined with actual working conditions of a certain type shearer. The analysis results show that cutting resistance and traction force of the shearer are not in a straight line, resulting in a significant axial force on the guided sliding boots, which is its main cause of damage; the maximum stress of the guided sliding boots is about 200 MPa, which is 70% of allowable stress; the weakest part of the sliding boots is located below pin hole; natural frequency and vibration mode of the guided sliding boots in normal cutting process of coal wall are obtained using modal analysis module in ANSYS software. The analysis conclusion can provide theoretical guidance for optimal design of the guided sliding boots of shearer.
