Structural Dynamics.
WORK EXPERIENCE
13th August 2012 – Present 2 years and 3 months experience in General Motors
Technical Centre India Private Limited, as a NVH
Engineer.
Powertrain Modal analysis Modelling the Powertrain model by using Simlab and
Hypermesh, followed by determining the modal
frequencies by using the Optistruct software. Lanzcos
method is used for modal analysis. From the analysis
different mode shapes is predicted for the model like
Horizontal bending mode, Vertical bending mode,
Diagonal mode, Twisting mode and local mode of some
components also.
Transmission – 6T45, 6T50, 6T80, M32, 9T45, etc.,
Shaft Modal Analysis For shaft assemblies also, modal analysis has been done
and different modes like horizontal, vertical and
torsional mode has been reported.
Shaft assemblies – Y4MHD, Y4MHD+, etc.,
Frequency response analysis Determining the response at the mount brackets of the
Powertrain model by providing spring stiffness and tip
mass at the mount locations. Displacement, velocity and
acceleration over the frequency range has been found by
applying a unit force in all directions. If the response is
over the critical limit, then the model will go for
structural modifications until the response will come
below the critical limit.
Transmission – X68F BEV2, CVT8 MR8, etc.,
Mount Boss Stiffness analysis Determining the boss stiffness of the mount brackets of
the Powertrain model by applying unit force at the boss

2. location (Inertia Relief Method). Local co-ordinate
system is created at the mount bosses and it is used to
measure the displacement of node with respect to origin
of system and from that stiffness is calculated.
Transmission – 6T45, 6T50, 6T80, M32, 9T45, etc.,
Radiated Noise Analysis Estimating the Pseudo sound power level of Powertrain
model over a desired frequency by calculating the
modal frequency of the model first, followed by
estimating the total average surface velocity (TAVNSQ)
of an element. By using an empirical formula, average
surface velocity of an element is converted to Pseudo
sound pressure level in dB.
Transmission – X68F BEV2, M32, F17 Gen2 and F19

M. Tech Dynamic instability characteristics of damaged composite plate like beam
under follower loading
Abstract The present work deals with the study of vibration, buckling and dynamic
instability characteristics of damaged cross-ply and angle-ply laminated plate
like beam under follower loading. The damage is anisotropic in nature and
parametrically incorporated into the composite using the concept of reduction
in stiffness. Finite element is used to obtain the governing differential
equation of the plate like beam. The effect of damage on the free vibration
and buckling characteristics of plate like beams has been studied. It has been
observed that damage shows a strong orthogonality and in general deteriorates
the vibration and buckling characteristics.

3. For follower type of loading, analysis is carried out on plate like beam
structure to obtain flutter characteristics. The effects of damage and its
location on flutter characteristics are studied. The desirable position of
damage on the plate like beam structure based on different stability behaviours
discussed. The results show that flutter is observed as primary modes of
instability when damaged plate like beam is subjected to follower loads. The
behaviour of flutter characteristics for different damage parameters is
discussed.
