Cavitation Effects on Squeeze-Film Damper Performance
A S L E Transactions, 1986 Experimental observations on unpressurized dynamically loaded hydrodynamic bearings and squeeze-film dampers indicate that cavitation bubbles, once formed, do not completely redissolve upon the reappearance of positive pressures. Instead, one is left with a spongy compressible fluid.

Small, EarlyView.A one‐step bulk integration of the surfactant Tween 20 into PDMS enables intrinsic and water‐triggered hydrophilicity. Combined molecular simulations and experiments reveal a dual mechanism where bound and mobile Tween 20 molecules cooperatively induce self‐activating, stretch‐tolerant, and long‐term wettability, supporting self‐driven liquid transport,

Seismic Design of Concrete Dams: An Integrated Risk‐Informed Performance‐Based (RIPB) Framework
Earthquake Engineering &Structural Dynamics, Volume 55, Issue 5, Page 1019-1049, 25 April 2026.ABSTRACT This paper advances the integration of risk‐informed principles into the seismic design of dams—a domain long guided by standards‐based, largely deterministic approaches. While performance‐based earthquake engineering is well established for buildings and bridges, its systematic adoption in dam engineering remains limited. We first address two

Machines, 2019 Turbomachine rotors, supported by little damped rolling element bearings, are generally sensitive to unbalance excitation. Accordingly, most machines incorporate squeeze film damper technology to dissipate mechanical energy caused by rotor vibrations and

Dynamic analysis of an elastic ring squeeze film damper supported rotor using a semi-analytic method
Engineering Applications of Computational Fluid Mechanics, 2020 To speed up the calculation of dynamic analysis for elastic ring squeeze film dampers (ERSFDs) and investigate the dynamic characteristics of ERSFD-rotor systems, a semi-analytic method (SAM) is proposed for analyzing oil film pressure and force.

Evaluation of shear mounted elastomeric damper [PDF]
, 1982 Viton-70 elastomeric shear mounted damper was built and tested on a T-55 power turbine spool in the rotor's high speed balancing rig. This application of a shear mounted elastomeric damper demonstrated for the first time, the feasibility of using ...

Advanced Functional Materials, Volume 36, Issue 20, 9 March 2026.A miniaturized mechano‐acoustic sensor is developed using an electrospun PVDF nanomesh as the diaphragm in a capacitive sensor structure. Unlike conventional nanomesh‐based sensors, it achieves high linear sensitivity, a broad and flat frequency response, and a compact form factor.

The Control of Engine Vibration Using Squeeze-Film Dampers [PDF]
Volume 5: Manufacturing Materials and Metallurgy; Ceramics; Structures and Dynamics; Controls, Diagnostics and Instrumentation; Education; Process Industries; Technology Resources; General, 1982 This paper describes the following roles of a squeeze-film damper when used in gas turbine applications as a means of reducing vibration and transmitted force due to unbalance. (a) as an element in parallel with a soft spring in a vibration isolator and (b) as an element in series with the stiffness of the engine pedestal.

On Dynamic Characteristics of ER Fluid Squeeze Film Damper
JSME international journal. Ser. C, Dynamics, control, robotics, design and manufacturing, 1995 This paper deals with an application of Electrorheological (ER) fluid to a squeeze film damper which enables reduction of whirling amplitude of rotor by adjusting the damping property at each rotating speed. An experimental model composed of a flexible shaft and a controllable ER squeeze film damper was constructed and its performance was studied under
