Fatigue and modal analysis of guided sliding boots of shearer
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 si...

| description | 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. |
