Force-Amplifying Compliant Mechanisms For Micromachined Resonant Accelerometers
(2013-04-04)
This thesis work provides an insight into the design of Force-amplifying Compliant Mechanisms (FaCMs) that are integrated with micromachined resonant accelerometers to increase their sensitivity. An FaCM, by mechanically ...
Characterization Of Al-Si Alloy Engine Bores For Tribological Studies
(2013-06-06)
Aluminum - Silicon alloys are recognized as appropriate materials for high performance cast components used in transportation powertrain applications. A combination of excellent wear resistance, good thermal conductivity ...
Pragmatic Design of Compliant Mechanisms using Selection Maps
(2018-04-02)
A pragmatic method for designing compliant mechanisms is developed in this thesis, by selecting among existing mechanisms one that may be modified as required. This method complements existing techniques by answering ...
Micro-PIV Study Of Apparent Slip Of Water On Hydrophobic Surfaces
(2010-07-01)
The condition of no relative velocity of fluid past solid is termed as ‘no-slip boundary condition’. This condition is a general observation in fluid mechanics. However, several research groups have recently reported slip ...
A Prestress Based Approach To Rotor whirl
(2010-06-02)
Rotordynamics is an important area in mechanical engineering. Many machines contain rotating parts. It is well known that rotating components can develop large amplitude lateral vibrations near certain speeds called critical ...
A Study Of Four Nonlinear Systems With Parametric Forcing
(2010-06-01)
This thesis considers four nonlinear systems with parametric forcing.
The first problem involves an inverted pendulum with asymmetric elastic restraints subjected to harmonic vertical base excitation. On linearizing ...
New Solution Methods For Fractional Order Systems
(2010-09-24)
This thesis deals with developing Galerkin based solution strategies for several important classes of differential equations involving derivatives and integrals of various fractional orders. Fractional order calculus finds ...
Experimental Investigation Of Rheocasting Using Linear Electromagnetic Stirring
(2011-02-09)
In several applications of casting, dendritic microstructure is not desirable as it results in poor mechanical properties. Enhancing fluid flow in the mushy zone by stirring is one of the means to suppress this dendritic ...
Transfer Layer Formation And Friction In Extrusion Of Aluminum : An Experimental Study Using A High Temperature Vacuum Based Pin-On-Disc Machine
(2010-09-21)
Hot extrusion of aluminum is widely practiced in industries for economic production of structural components. The surface finish and tolerance of the extruded components, both from design and aesthetic requirement, are ...
Kinematic And Static Analysis Of Over-Constrained Mechanisms And Deployable Pantograph Masts
(2011-01-19)
Foldable and deployable space structures refer to a broad category of pre-fabricated structures that can be transformed from a compact folded configuration to a predetermined expanded configuration. Such deployable structures ...
