PROJECT PROFILE:

CAE ANALYSIS :

PROJECT # 1

Title :Structural analysis of Locomotive

Description : The typical structural analysis for the locomotive is

done as follows: The locomotive is analyzed for static yield and

crashworthiness

loadcases, fatigue analysis and modal analysis.The procedure of analysis

is first the locomotive is analyzed for static loadcases. If the

stresses are above yield limit the design changes are suggested to reduce

the stresses below yield limit for the static loadcases. The

crashworthiness loadcases are analyzed simultaneously. If the stresses are

above ultimate strength of the material the design changes are

suggested to reduce the stresses below ultimate limit.Once the locomotive

meets the criterion for the static and crashworthiness loadcases, fatigue

analysis is performed on the locomotive. Once the locomotive meets minimum

life criterion of the fatigue analysis, modal analysis is performed. Once

the dynamic behavior of the locomotive is acceptable, the results are

documented.

The static loadcases are inertia loadcases, Buff (compressive force on

locomotive), Drag (tensile force on the locomotive), Lifting of the

locomotive from each end (other end being on the track), lifting of the

locomotive from both ends.

The crashworthiness loadcases are performed as per S580 or EN standards

as applicable.

Fatigue loadcases include set of inertia loadcases, and tractive &

dynamic brake loadcases.

In the same way 7 different locomotives were analyzed for 6 different

customers. Ansys is used for all these analysis. FE Safe is used for

the fatigue analysis.

PROJECT # 2

Title : Strength analysis of clip-in cursor.

Description : Main aim of the project was to predict the

strength of the clip-in cursor. The cursor is part of window regulator

mechanism. The cursor is rigidly connected to the glass The cursor slides

on the window regulator rail to raise

or lower the glass.

The loadcase considered was as follows : The cursor was fixed and the

glass was being pulled upwards. Glass and

the cursor were modeled .A standard contact was defined between glass and

the cursor. Nonlinear material

properties were used for the cursor.

PROJECT # 3

Title : Stall load analysis of window regulator

rails.

Description : Main aim of the project was to predict the

strength of the clip-in cursor. The cursor is part of window regulator

mechanism. The cursor is rigidly connected to the glass The cursor slides

on the window regulator rail to raise

or lower the glass.

The loadcase considered was as follows : The cursor was fixed and the

glass was being pulled upwards. Glass and

the cursor were modeled .A standard contact was defined between glass and

the cursor. Nonlinear material

properties were used for the cursor. In the similar way different

parts of window regulator mechanism were analyzed for their respective

loadcases.

PROJECT # 4

Title : FE modeling and Analysis of Hood assembly.

Client : Nissan.

Description : Main aim of this project was to prepare FE Model

of hood NVH analysis.

After the FE modeling hood assembly was run for normal mode analysis its

rigid body modes, zero frequency mechanism modes and other

mode shapes were checked. NASTRAN was used as solver.

PROJECT # 5

Title : FE modeling and Analysis of Battery mounting

assembly.

Client : Nissan.

Description : Main aim of this project was to compare stresses

on battery mounting bracket under 60 N load for its three design variations.

Boundary conditions and loading conditions were provided by the client.

NASTRAN was used as solver.

PROJECT # 6

Title : FE modeling and Modal Analysis of turbo

charger mounting bracket.

Client : International Trucks And Engine Corporation Ltd.

Description : Main aim of this project was to achieve target

natural frequency of 40 Hz.

Modal analysis was carried out on turbo charger mounting bracket .Two

design variations were made to achieve this.

NASTRAN was used as solver.

CAE MODELING :

PROJECT # 1

Title : FE modeling of Floor console.

Client : Ford

Description : Main aim of this project was to prepare FE model

of console and strength and durability analysis of the console for its

various load cases.

PROJECT # 2

Title : FE modeling of Overhead console.

Client : Ford

Description : Main aim of this project was to prepare FE model

of overhead console for durability analysis for its various load cases.

PROJECT # 3

Title : FE modeling of body side assembly.

Client : Nissan

Description : Main aim of this project was to prepare FE Model

of body Side assembly for NVH

analysis.

The meshing was done using linear quadrilateral shell elements.FE

modeling of other assemblies like dash panel, rear bumper assembly,

door trim assembly, door assembly, hood assembly etc was done same as

above.

PROJECT # 4

Title : FE modeling of V6 cylinder block.

Client : General Motors

Description : Main aim of this project was to prepare FE Model

of Cylinder block for NVH analysis.

Cylinder block geometry was segregated in oil circuit, water jacket, and

outer body and misc. components. These components were

meshed using linear triangle elements and after getting closed volume,

tetra was generated.Finally second order tetrahedral element model

was delivered.FE modeling various V8 cylinder block, V4 cylinder block,6

cylinder Inline block, cylinder head was carried out in the same

manner.
