Week 2 Railwheel and Track

Objective :- Multiply the bearing load by 5 times and compare the results with the load of 100000N. Compare the total deformation , Equivalent stress and the life under both the loads.

STEPS;-

1. Import geometry

2. Defining the joints

3. Meshing

4. Applying loads

5. Running the simulation and result analysis

Importing Geometry:-

The geometry is imported into the workbench from the given assembly file. The materials defined is structural steel. The following properties are there for structural steel.

Geometry:-

Procedure:-

- Update model to work on the model

- Under model-Geometry assign the name for railwheel and track setups based on their application.

- Under connections create a contact between railwheel and track by selecting the faces and provide their contacts as frictional with friction coefficient 0.3.

Create a translational joint on shaft as it translates in x direction along with wheel

Create a fixed joint on track as it is fixed on which the wheel and shaft move.

Mesh the model by assigning the element size as 35mm for whole geometry.

The following settings are used for analysis in the -

- Large deflection is ON 

- Solver type is direct

- Output controls made YES for stress, strain, Nodal forces, etc

- Bearing load is set to 10^5 N in load case 1 and 5*10^5N in load case 

-Translation given is 500mm to shaft.

Case 1- In this case the results are evaluated based on bearing load of 100000N and 500000N respectively

For 100000N bearing load.

Total deformation:-

For 500000N bearing load

Total deformation is :-

Case 2 - User defined result for maximum deformation is taken out for 100000N bearing load and then compared with Ansys in build deformation.

As visible the user defined result for sqrt(UX^2+UY^2+UZ^2)=999.94 Total deformation is similar to ansys result for the total deformation which is 1000mm. so its verified.
