Vibrational energy flow analysis using a substructure approach: the application of receptance theory to FEA and SEA [PDF]

, 1997
A method for studying the vibrational energy flows through structures based on receptance theory is presented. The structures are considered to be made up of subsystems, which may, in turn, be substructures modelled by using finite element analysis (FEA),

A Simple Method to Design and Analyze Dynamic Vibration Absorber of Pipeline Structure Using Dimensional Analysis

Shock and Vibration, Volume 2020, Issue 1, 2020., 2020
Vibrations due to mechanical excitation and internal and external fluid flow can cause fatigue in pipelines and leaks in fittings. A beam‐based dynamic vibration absorber (beam DVA) is a device comprising an L‐shaped beam with a concentrated mass at its free end that can be used to absorb and dissipate vibrations in the pipeline.

Study on Steady‐State Responses of High‐Speed Vehicle Using Infinite Long Track Model

Shock and Vibration, Volume 2020, Issue 1, 2020., 2020
The coupled vehicle/track dynamic model is formulated through integrating a high‐speed rail vehicle model with a slab track model via the wheel/rail contact model. The sliding window method is improved using the least square criterion to simulate the vehicle travelling along the infinite long track.

Improvement of boring operations by means of mode coupling effect [PDF]

, 2022
Boring bars are inherently slender tools which are prone to show chatter problems due to their low dynamic stiffness and damping, being this problem their main limitation in productivity. The onset of chatter is mainly related to the dynamic stiffness of

Using the inverse finite‐element method to harmonise classical modal analysis with fibre‐optic strain data for robust population‐based structural health monitoring

Strain, Volume 61, Issue 1, February 2025.
Abstract Vibration‐based approaches to structural health monitoring (SHM) gained increasing significance for assessing the behaviour of existing structures because of their non‐intrusive nature and high sensitivity to damage. However, data availability often limits the application of SHM approaches.

Simulation tool for chatter prediction of varying tool–machine configurations based on dynamic substructuring

, 2023
163168Cutting tools of different type, shape and size are used in milling processes. Every individual tool changes the dynamic behavior of the system and results in varying occurrences of chatter vibrations.

Adaptive Feedforward Vibration Control of Helicopter Cabin Floor Driven by Piezoelectric Stack Actuators: Modeling, Simulation and Experiments

International Journal of Aerospace Engineering, Volume 2025, Issue 1, 2025.
Active control of structural response is the most practical and effective approach to mitigate helicopter vibration and enhance ride quality. In this paper, adaptive feedforward vibration control is constructed for the helicopter cabin floor driven by piezoelectric stack actuators (PSAs).

RCSA-Based Analysis of Stability Lobes in Milling Incorporating Tool Clamping Errors

Machines
This study proposes a methodology for selecting robust stable cutting conditions from a Receptance Coupling Substructure Analysis (RCSA)-based Stability Lobe Diagram (SLD) by considering tool clamping errors that may occur during operator tool setup ...
