Week 7-Long Piston With Cam

AIM:

To perform the cam and follower simulation and obtain the results for frictional and frictionless contact.

METHODOLOGY:

• Import the geometry and assign the material to the components from the engineering data.
• give the frictionless contscts wherever necessary
• 
• givethe fixed joint to the barrel and revolute joint to the barrel cam followed by translational joint to the barrel and follower.
• 
• 
• mesh the geometry and perform face sizing operation.
• 
• perform the analysis in 9 steps and give the joint rotation to the barrel cam.
• 
• run the simulation and obtain the reqiured results and follow the same procedure for frictional contacts.

RESULTS:

CASE 1:

CASE 2:

friction coefficient=0.1

Tabular data:

case	directional deformation(mm)	equivalent stress(Mpa)	equivalent strain
1	20.442	7494.7	0.03763
2	20.442	7936.4	0.03985

CONCLUSION:

Due to the friction coefficient the frictional force develops between the surfaces that are in motion which results in increase in stress in the components.
