IC Engine Valve Train Mechanism
CAM
CASE I
Cam lift = 3.5mm.
Material = Cast Carbon Steel
Speed = 1500 rpm
Spring Stiffness = 10N/mm^2
7200 frames per second
CASE II
Cam lift = 6 mm.
Material = Cast Carbon Steel
Speed = 1500 rpm
Spring Stiffness = 10N/mm^2
7200 frames per second
Results
CamLift
for 3.5mm = 53mm
for 6mm = 56mm
Contact Forces
Between Cam and Pushrod
for 3.5mm
for 6mm
Between Pushrod and rocker
for 3.5mm

Between Rocker and Valve
for 3.5mm
for 6mm
Observations
Contact Force Along X Direction represents Frictional force and Magnitude represents Net contact force between various parts, this shows negative value of force is acquired in during the magnitude of the contact forces.
