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.

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.
