Week 2 Railwheel and Track

Aim: Perform a static structural analysis on the Railwheel and Track setup according to the given conditions.

Procedure:

• Open Ansys Workbench and select static structural. Assign the material in engineering data and import the model in spaceclaim.
• Update the model and click on edit and rename as per convenience.
• Under connections, create contacts between faces of railwheel and track as frictional with coefficient value of 0.3.

• Similarly, create contact between railwheel and shaft but this time, frictionless.

• Now we need to assign different types of joints between different components
• Translational joint is created for shaft of the wheel as it translates in a specified direction.

• Planar joint is created for wheel as it move in straight line over the track.

• Track is assigned to be a fixed joint over which wheel, along with the shaft moves.

• Assign elemnt size of 50mm for mesh to be created for whole setup and 35mm element sized mesh for the contact faces between railwheel and track.

• Apply the following analysis setting under static analysis.

• Create Joint for the shaft for specifying its transition distance of 500mm along the track under static structural section.

• Create a bearing load as well acting downwardsover the inner circumference of wheel.

• Finally, insert equivalent stress, equivalent ealstic strain total deformation, etc and hit solve to obtain the following results.

Results:

Parameter	Bearing load of 100000 N	Bearing load of 500000 N
Total Deformation
Stress 1
Stress 2
Strain 1
Strain 2
Life
User defined

Conclusion:

• Significant changes in stress and strain can be observed.
• Life span decreases drastically when a higher load is applied.
• Total deformation calculated by software default equation and user defined match perfectly.
