Accurately predicting the nonlinear dynamic response of shaft-disk rotors is crucial in the
design of rotary machines. In available studies, the disk is commonly treated as rigid body to …

Bolted joints are major components to connect the multiple stages of disks in the aero-
engine, which directly influences the motion state of the rotor system. This paper studies the …

This paper studied the mass-eccentricity nonlinear evolution in fretting slip process. Firstly, a
mechanical analysis of combined Jeffcott rotor under rotating condition is carried out, and …

This study is dedicated to investigate the nonlinear dynamics of a system composed of a
flexible rotor shaft carrying a longitudinally dispositioned unbalanced rigid disc. The less …

One of the main causes for failure in the rotor machine is the presence of internal cracks in
the shaft rotating at high speed. The occurrence of such cracks has a dangerous and …

Sommerfeld effect is a nonlinear jump phenomenon which occurs in unbalanced rotor–
motor system, and its characteristics provide an idea of power required to operate the …

In order to reduce the x-direction and Y-direction displacement disturbance of the barrel and
improve the firing accuracy, based on Bernoulli Euler's theoretical assumption of beam and …

In order to overcome the low efficiency of nonlinear dynamic solution, a hybrid deep neural
network (HDNN) is constructed based on the integrated deep learning networks for both …

Analyzing the dynamic characteristics of an aero-engine rotor-bearing system helps
professionals predict and judge the dynamic behavior of aero-engines. It is different from the …
