Railwheel and Track

Objective:

To perform a static structural analysis on the Railwheel and Track setup and compair the results for two diffrent load condition.Also note any change in results when a user defined result is used.

Setup:

• Import geometry

• Define connections

Frictional contact with friction coefficeint 0.3

Frictionless contact

• Define joints

Fixed joint

Translational joint

Planer joint

• Material

• Meshing

Base mesh 50mm

face meshing 35mm

• Define loads

Case 1 :Bearing load in -ve y direction of 1e+5 N

Case 2 :Bearing load in -ve y direction 5e+5

Displacement

• Solver settings

  Large deflection ON

  Solver type direct

Dynamic time step ON

• Run & analyse the results.

Case 1:

For 1e+5 N load

Max stress 145.53Mpa

Total deformation: 1001.6mm

Life:

For 5e+5N

Max stress 524.74Mpa

Total deformation:

Life:

Report:

for 1e+5 N load

for 5e+5N load

Case 2:

User defined function for deformation.

User defined expression for deformation was set and deformation was found to be same as total deformation

Conclusion:

• Life decreases as can be observed from the report as load increased
• More chances of failure in case of increased load as safety dactor in case of increased load was observed to be 0.624
• Max stress induced was more for increased load case
• Max deformation was observed to be same for both
