Week 2 Railwheel and Track

Railwheel and Track

AIM:

Case 1: Multiply the bearing load by 5 times and compare the results with the load of 100000 N (As done in week 2 video). Compare the Total Deformation, Equivalent stress, and the life under both the loads

PROCESS:

• Download the file and import into geometry of static structural in ansys
• Add the material in engineering data

• 

• Open the model and update before that

• 

• After opening check the material for both the gears in geometry section
• Keep the stifness behivaour as Flexiable as this is gone a Translate

• Connections are made using contacts & Joints
• Incontacts select the track & Wheel surfaces joints that will be contact

• In Second case select Wheel & Shaft surfaces joints that will be contact (Keep it frictionaless)

• In joints:
• Fix the track

• Provide translation to shaft

• Provide plane for wheel as it should not move

• Keep mesh as defalt and face size the contact surfaces

• In static structure we made the steps as 10 for better results

• Put the given bearig load as given 100000N

• Provide displacement for the joint

• In solution insert the required analysis that needs to be done

• For the bearing load by 5 times duplicate the current static structural

• Open model and change the bearing load as given & clear the solution and go for solve

• Multiply the bearing load by 5 times and compare the results with the load of 100000 N (As done in week 2 video). Compare the Total Deformation, Equivalent stress, and the life under both the loads

	FOR the load of 100000 N	FOR the load of 500000 N
Total Deformation	562.12MM	624.96MM
Equivalent stress	109.83MPa	257.03MPa
LIFE	1e^6	1e^6

Case 2: Implement a User-defined result and calculate the Total Deformation from this result and check if it is the same as that obtained by the inbuilt result by ANSYS for a load of 100000 N.

Total Deformation from this result by ansys

User-defined result

CASE 1 CONCLUSION:

By the data observation we can say that :

• The total deformation length has increased by 62.84mm as the load has increased to 500000 N
• The Equivalent stress has increased by 147.2MPa as the load has increased to 500000 N
• Life expected of both loads is same

CASE 2 CONCLUSION:

YES BOTH ARE SAME
