LONG PISTON WITH CAM CHALLENGE
OBJECTIVES
In this challenge, we have to perform a transient analysis on a piston and cam mechanism model that has been provided to you. You need to run the analysis with Frictionless contact, Frictional with 0.1 and 0.2 as the frictional contact for a total of 3 cases. Find out the Equivalent Stress, Directional Deformation and Equivalent Elastic Strain and compare them for all the three cases. Give an inference as to why the results vary between cases.
PROCEDURE
Then mesh the component with required mesh size in this assignment we will use
RESULTS
Case1 – Frictionless
Directional Deformation
Equivalent stress
Equivalent strain
Total Acceleration
Contact Pressure
Case2 – Frictional 0.1
Directional Deformation
Equivalent stress
Equivalent strain
Total Acceleration
Contact Pressure
Case1 – Frictional 0.3
Directional Deformation
Equivalent stress
Equivalent strain
Total Acceleration
Contact Pressure
CONCLUSION
Directional Deformation (mm) | Equivalent strain | Equivalent stress (MPa) | Contact Pressure (MPa) | |
Case 1 | 20.372 | 0.008829 | 1756.6 | 1329.8 |
Case 2 | 20.513 | 0.00959 | 1849 | 1285.4 |
Case 3 | 20.551 | 0.01210 | 2339.3 | 1374.2 |
From the above stimulation result it is clearly understand that if coefficient of friction increases the stress and strain also increases because the frictional force always act on opposite direction of the motion and cause restiction to motion.
