Bolted Joints Disassembly: A Field Study for Thermal Influence on Large Diameters

Abstract

During maintenance operations, technicians have to work as quickly as possible. But they are often stopped during disassembly by blocked bolts or studs. This paper examines causes of blockage and suggests new method for disassembling bolted joint in this case. Several methods are analyzed and tested with finite element simulations. An experimental protocol to test a new disassembling method is also introduced in this paper.
