NExT‐LF: A Novel Operational Modal Analysis Method via Tangential Interpolation

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Operational modal analysis (OMA) is vital for identifying modal parameters under real‐world conditions, yet existing methods often face challenges with noise sensitivity and stability. This study introduces NExT‐LF, a novel method that combines the well‐known Natural Excitation Technique (NExT) with the Loewner Framework (LF). NExT enables the

Uncertainty Quantification for Nonlinear Vibration of Supercritical Drive Shaft With a Dry Friction Damper

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The supercritical drive shaft is becoming increasingly popular in helicopter transmission system. Dry friction dampers are specially employed to ensure the supercritical shafts crossing the critical speed safely. Due to design tolerances, manufacturing errors and time‐varying factors, the parameters of the damper are inherently uncertain ...

Optimization Study on Battery Thermal Management System With Coupled Air and Microchannel Liquid Cooling Strategy

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Because of the surging demand for clean energy, the performance and safety of lithium‐ion batteries (LIBs) for energy storage and conversion have received much attention. This study presents a battery thermal management system (BTMS) that combines air cooling with microchannel liquid cooling.

Effect of Variations in the Ring Thickness on the Dynamic Performance of the Bimetal Gears

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study used a six‐degrees‐of‐freedom dynamic model to analyze the dynamic response of bimetal spur gears. Aluminum alloy forms the core of the bimetal gears, and a uniform‐thickness steel ring surrounds the teeth. Gear mesh stiffness of bimetal gears and the transmission error have been assessed using a numerical approach based on finite ...
