Vibration fatigue analysis of the main pulley frame of a rotary drilling rig based on a real vehicle test

The pulley frame of a rotary drilling rig is located at the top of the mast and plays the role of changing the direction of wire rope movement. For a certain type of rotary drilling rig, the front cover plate of the main pulley frame was cracked and damaged during the working process, and the vibrat...

Summary:The pulley frame of a rotary drilling rig is located at the top of the mast and plays the role of changing the direction of wire rope movement. For a certain type of rotary drilling rig, the front cover plate of the main pulley frame was cracked and damaged during the working process, and the vibration signal of the pulley frame was tested under the relevant working conditions using the test method. 3D computer-aided design (CAD) modelling of the pulley frame was performed using the Creo software, from PTC [1]. The CAD model was used to create a finite element model using ANSYS [2] software. An analysis was performed using ANSYS Workbench and the nCode Designlife [3] software to provide a fatigue life estimation of the main pulley frame, focusing upon a random vibration fatigue life analysis approach. This paper describes an approach for industry and academia to analyze, design and optimize such pulley frames for rotary drilling rigs.
