The mesocrystal showing both electrorheological and magnetorheological effects is called electro-magnetorheological (EMR) solids. Prediction of the overall magnetic properties of the EMR solids is a challenging task due to the coexistence of the uniaxially anisotropic behavior and structural transition as well as long-range interaction between the suspended particles. To consider the uniaxial a...

Title of Document: ADAPTIVE MAGNETORHEOLOGICAL SEAT SUSPENSION FOR SHOCK MITIGATION. Harinder Jit Singh Doctor of Philosophy, 2014 Directed By: Norman M. Wereley Minta Martin Professor and Chair Department of Aerospace Engineering This research focuses on theoretical and experimental analysis of an adaptive seat suspension employing magnetorheological energy absorber with the objective of minim...

Engine is the main source of vibration that generates unwanted noise and vehicle chassis. Especially, in submarine applications, radiation signatures can be detected at some distance away from using a sonar array. Thus quiet operation crucial for submarine’s survivability. This study addresses reduction force transmissibility originating engines transmitted to hull through engine mounts. An ine...

Abstract This paper demonstrates the importance of assessing whirl flutter stability propeller configurations with a detailed aeroelastic model instead local pylon models. Especially growing use electric motors for propulsion in air taxis and commuter aircraft becomes an important mode instability. These often include which are powered by lightweight located at remote locations, e.g. wing tip. ...

An important cause for interior noise in vehicles is structure-borne sound from the engine. The vibrations of the source (engine) are transmitted to the receiver structure (the vehicle) causing interior noise in the vehicle. For this reason the engine is supported by rubber isolators for passive isolation in especially the high-frequency region. To make a good judgment of the characteristics of...
