Week 7-Long Piston With Cam

Aim - To simulate transient analysis on piston and cam model with frictionless contant and with friction contact with coeefiient of .1 and .2

Procedure-

1.we will import the model and check the geometry in the spaceclaim.

2.we add structural steel as material in the engineering data for whole compoment.

3.we create contact between the compoments.

4. we provide fixed joint to the barrel ,revolute joint the cam follower and translational body to body to the long pistion.

5.we provide face sizing bewteen the long piston and cam follower of elemntal sixe of 3mm.

6.we provide numer of steps as 9 for the intial step we provide maximum time step as 0.2 and fro 2 to 9 we provide maximum time step as 0.3 sec.

7.we provide joint load as rotation to the cam the follower in the clock wise direcrtion.

8.we solve for directional deformation,equivalent stress,and equivalent strain.

for case 2 with frictional coeeficient .1

for case .2

Equivalent stress	Directional deformation	Equivalent starin
1863.9	10.951	0.0093
2257.9	11.068	0.011337

conclusion as the firction increses the there will be more surface contact take place hence stress increase and deformation increase. hence we have less stress in the case of frictionless contact.
