Modeling and Dynamic Analysis of a Rotating Shaft-Disk System with Contact Friction at the Bolted Interface

Опубликована: Янв. 1, 2025

Highly loaded rotor systems, such as those in aero-engines, exhibit complex vibration behaviors due to the discontinuities bolted structure, which generate friction at connection interfaces. This leads nonlinear dynamics for system. A dynamic model of system is established using finite element theoretical Methods, incorporating connections around entire circumference. The procedure assessing stick-slip states bolts different positions during motion provided. study examines phenomenon interface under various conditions, including preload values, rotational speeds, bolt numbers, and coefficients. Trends equivalent stiffness energy dissipation these conditions are analyzed. Additionally, critical force each stage speeds discussed. region viscous-slip-shear state also presented. research introduces a modeling approach understanding characteristics systems operating viscous-slip regime their It provides an analytical that serves foundation design calculation interfaces engineering applications.
