The bolt connection structure is widely used in the connection of aeroengine parts, and its
connection quality is very important, as it can directly affect the geometric and dynamic …

Bolted joints are the major connection form to hold the aero-engine rotor system as a
discontinuous entirety. What is noteworthy is that the bolt assembly process (BAP) directly …

Preload relaxation, caused by elastic interaction between tightened bolts, is one of the major
reasons for non-uniformity of pretension force. But how to accurately assess the residual …

The preloading variation of bolt joint relies on the elastic interaction between tightened bolts
significantly. But how to characterize the elastic interaction essentially and truly is still an …

This paper proposes a new method to measure the axial stress of bolt based on the
combination of first trailing (T 1) wave and shear (S) wave ultrasound using an …

The use of electrical resistance as a diagnostic parameter in structural health monitoring of
bolted joints is discussed in the paper. The proposed method is based on the phenomenon …

Loss of clam** force due to elastic interaction is unpredictable and nonnegligible with the
typical non-linear characteristics of gasketed joints. It is hard to weaken or eliminate elastic …

Bolted flange joints are the most popular type of connection of pressure vessels and pi**
equipment because of their ease of assembly and disassembly. However, the initial …

This paper studied the interface non-uniform slip phenomenon and proposed a
characterization model. Firstly, by analyzing the mechanical status of combined rotor during …

Bolted flange joints are widely used to connect pressure vessels and pi** equipment
together and facilitate their disassembly. Initial tightening of their bolts is a delicate operation …
