In this paper, the aero-engine test with inter-shaft bearing fault is carried out, and a dataset is
proposed for the first time based on the vibration signal of rotors and casings. First, a test rig …

The inner ring dynamic misalignment of deep groove ball bearings (DGBBs), as a possible
error type in practical engineering, has significant influences on the service performance of …

Clearance fit is a common assembly method for bearings in rotor systems, which leads to a
certain clearance between the outer ring of the bearing and the bearing pedestal, that is, the …

In order to study the vibration characteristics of inter-shaft bearing failures of a dual-rotor
system, an eight-degree-of-freedom dynamic model of dual-rotor system containing inter …

Many advanced aeroengines are typically designed with coaxial coupling dual-rotor
structures. As a result, the vibration responses of the rotor system are characterized by …

Diffusion models have demonstrated powerful data generation capabilities in various
research fields such as image generation. However, in the field of vibration signal …

Spindle-bearing systems are widely used in machine tools, aero engines, and other
industrial equipment. The vibration characteristics of the spindle system may be affected by …

Rotating blade is highly susceptible to cracking in harsh conditions, which seriously affects
the dynamic characteristics of the power equipment. Existing research focuses primarily on …

The inter-shaft bearing is a critical but vulnerable component of dual rotors, because of the
severe operational conditions and loads. This paper investigates the failure mechanism of a …

Abstract Bistable Deployable Composite Boom (Bi-DCB) can achieve bistable function by
storing and releasing strain energy, which has a good application prospect in space field …
