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