Modeling of the Haltere-A Natural Micro-Scale Vibratory Gyroscope
(2018-06-05)
Vibratory gyroscopes have gained immense popularity in the microsystem technology
because of their suitability to planar fabrication techniques. With considerable effort in design and fabrication, MEMS (Micro-electro-mec ...
Numerical Modelling and Software Development for Analysing Squeeze Film Fffect in MEMS
(2018-06-05)
The goal of the current study was to develop a computational framework for modelling
the coupled fluid-structure interaction problem of squeeze films often encountered in
MEMS devices. Vibratory MEMS devices such as ...
Fundamental Studies On Tribological Response Of Titanium And Copper
(2007-08-22)
Friction and wear have been observed m mechanical systems when there is a relative motion between two solid bodies Friction mainly results in loss of energy and wear results in matenal loss The proper understanding of ...
Effect Of Squeeze Film Flow On Dynamic Response Of MEMS Structures With Restrictive Flow Boundary Conditions
(2011-07-08)
There are many ways in which the surrounding media, such as air between an oscillating MEMS structure and a fixed substrate, can affect the dynamic response of a MEMS transducer. Some of these effects involve dissipation ...
Experimental And Analytical Investigations Into Development Of Double-Tuned Expansion Chambers And Extended Concentric Tube Resonators
(2011-07-08)
The performance of an acoustic filter (or muffler) is measured in terms of one of the following parameters: Insertion Loss (IL), Level difference (LD) and Transmission loss (TL). All these three parameters may be evaluated ...
Estimation of Stress Concentration and Stress Intensity Factors by a Semi-Analytical Method
(2018-05-29)
The presence of notches or cracks causes stresses to amplify in nearby regions. This phenomenon is studied by estimating the Stress Concentration Factor (SCF) for notches, and the Stress Intensity Factor (SIF) for cracks. ...
CFD Studies Of Pulse Tube Refrigerators
(2012-12-06)
The performance evaluation and parametric studies of an Inertance Tube Pulse Tube Refrigerator (IPTR) are performed for different length-to-diameter ratios, with the Computational Fluid Dynamics (CFD) package FLUENT. The ...
Role Of Boron On The Evolution Of Microstructure And Texture In Ti-6AL-4V-0.1B Alloy
(2013-06-04)
Titanium and its alloys constitute an important class of materials for aerospace, biomedical, and chemical industries, primarily due to their high specific strength and fracture toughness with good corrosion resistance. ...
