| Lift laws are defined by PERFECT CAM according to the most
proven standard in manner simple and effective. Specifically this allows you to: |
LIFT
calculates lift laws in manner simple and effective
|
|
|
define the lift law, choose from three types of laws polydyne, a specially designed trigonometric
and a polynomial. |
|
|
define the ramps choosing a law or parabolic
or cycloidal. |
|
The ramps and the lift law are automatically connected in the appropriate
manner so as to minimize the cause of vibrations. |
|
| For direct attack valve train systems with flat or symmetric
roller tappet PERFECT CAM calculates analytically cam profile with a step in grade
ten. For an immediate assessment of the feasibility are shown: |
CAM
calculate the cam profile for direct attack valve train systems to verify the
feasibility
|
|
|
the graphs of the cam already oriented
respect to fire TDC, depending on the direction of rotation of the camshaft and on the
type of cam (intake or exhaust). |
|
|
the radius of curvature |
|
|
the minimun diameter of tappet |
|
|
the maximun pressure angle |
|
The cam profile is stored in polar coordinates, both in cartesian
coordinates for easy use of the output from the machine of realization. |
|
| To verify the behavior of the valve train system PERFECT CAM
calculates: |
VALVE TRAIN
verify the right operation of the valve train system
|
|
|
the elastic force of helical springs (single
or double). |
|
|
the forces between cam and tappet and check
whether there are conditions of valve float.. |
|
|
the lubrication conditions between cam and tappet
to evaluate the friction. |
|
|
the hertzian pressure to evaluate surface
wear. |
|
OUTPUT
the results are easily visible and usable |
PERFECT CAM at the end of the calculation shows the numerical results immediately with
a series of graphs relating to significant data, together
with this, it creates a set of files with stored the data for easy
use in spreadsheets or in machines designed to perform the processing of the cam . |
