Week 7-Long Piston With Cam

Aim :

The aim is to analyse the given model.

Objective:

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.

Procedure:

Initially open up the ansys workbench,

then open up the model and edit it in the mechanical ansys,

change the names and reframe it,

Add and delete the contact point,

now generate the mesh and

give the joint rotation,

change the required static analysis settings,

and add the solution requirements,

finally solve it and save it as archive.

Case 1 :

Case 2:

Case 3:

Result :

Case	Strain mm/mm	Directional deformation mm	Stress Mpa
1	0.00647	10.883	1681
2	0.0075	10.881	1492
3	0.00902	20.357	1789

From the above table we can see that as the frictional co-efficient increases the equivalent stress, strain and Directional deformation increases. As there is friction the energy required also increases hence the stress and strain also increases. Total deformation remains constant for all three cases.More force is required to over come the friction and force is directly proportional to stress thus the stress increases. Stress is directly proportional to strain and thus strain increases.
