7) Stress and displacement Analysis of
Centrifugal Impeller
Centrifugal impeller has
a complex three-dimensional geometry. It is subjected to centrifugal, thermal
and fluid forces in addition to the residual stresses developed due to
interference between mating parts. An attempt was made to analyze impeller to
evaluate stresses and deflections due to the above forces.
Design and analysis of the centrifugal impeller
under actual working conditions is a multistage analysis in which the thermal
analysis is carried out first and then the stresses caused due to the thermal
loads are converted into body forces and then applied to the model. The static
stress analysis is then carried out applying the relevant boundary conditions.
Tools used :
ANSYS 8.0
8) Stress and displacement Analysis of Thrust
Balancing Disc
Balancing disc has a simple three-dimensional
geometry. It is subjected to centrifugal, thermal and fluid forces in addition
to the residual stresses developed due to interference between mating parts. An
attempt was made to analyze the original balancing disc to evaluate stresses
and deflections due to the above forces.
From the first stage of analysis carried out on
the original designed Disc, it was find out that the Vonmises
stresses were within tolerable limits but the radial growth of the inner
diameter of the Disc was much more than the radial growth of the outer diameter
of the shaft. Hence some modification was carried out in the existing design in
order to maintain the interference fit in the running conditions also. The
modified design was also analyzed separately and concluded that the design was
safe.
Tools used :
ANSYS 8.0
9) Structural analysis and optimization of Radial
Turbine Rotor for Micro Gas Turbine Unit
Radial
turbine rotor was analyzed for different loads such as inertial, thermal loads
and cyclic symmetry boundary conditions. Analysis indicated that the centrifugal
stresses developed in the rotor were exceeding the yield limit. From the
results of computational simulations, conclusions were drawn to make necessary
changes to the existing design.
Design
optimization was carried out with minimization of mass as design objective, the
structural shape as design variable and centrifugal stresses developed as the
design constraint. Various configurations involving necessary design changes
were modeled and analyzed. Finally for the given set of properties, geometry
and boundary conditions the geometry that yields better result was considered.
Tools used :
ANSYS 8.0
10) Analysis of
Vibrational Characteristics of Radial Turbine used in Micro Gas Turbine
In Turbo machinery, the study of vibration
characteristics of individual components is an integral part of the design.
Radial Turbine was analyzed by taking the advantages of cyclic symmetry i.e.
only one sector to represent the behavior of the entire structure. Analysis was
done keeping in mind to take into account the thermal loads & inertia load.
In order to introduce the stress stiffening effect into the model a prestressed analysis carried out first & these effects
were used in subsequent modal analysis.
Tools used :
ANSYS 8.0
11) Vibration and critical
speed analysis of Engine shaft
The
high speed of operation of the MicroGas Turbine makes the critical speed
analysis a critical issue. Shafts have to be designed such that the critical
speed does not coincide with the operating RPM. Custom made software and parallel
FE analysis was adopted.
Tools used :
ANSYS 8.0
