| The definition of the lift law is the heart of
the design of a cam, to this are linked the performance, the feasibility and the
reliability. For this PROFESSIONAL CAM is designed to offer the best
and most diverse opportunity to define the lift law. |
PERFORMANCE
calculate the lift to obtain the maximum permeability and to harness the
pressure wave effects 
|
|
|
Have been introduced the laws more proven
to determine profiles in manner easy and reliable. |
|
|
Have been developed and implemented laws to make
more or less aggressive profiles as required. |
|
|
Have been studied and implemented laws to change
the patterns of accelerations and jerk to meet the most critical and diverse needs
dynamic-vibration. |
|
|
Solutions were introduced for the calculation of asymmetric
laws to obtain the best performance especially in racing race. |
|
|
Besides this was inserted the opportunity to import
lift laws experimentally measured, with a special algorithm
to support the filtering of data, essential to correct errors of measurement and
achievement. Without this filter is very difficult to exploit the experimental data. |
|
| Each distribution system and any machine for the
realization has characteristics that would require a specific calculation of the cam
profile, so PROFESSIONAL CAM has implemented all the main valve
train systems so as to translate the lift law previously set in the correct profile
and verify whether this is feasible with machine of realization that you have. |
FEASIBILITY
calculate whether the cam is feasible in relation to the lift law chosen and
the valve train system 
|
|
|
Is calculated the evolution of the radius of
curvature of the cam at each angle and immediately showed the minimum radius of curvature
of the profile. |
|
|
Is calculated and stored the evolution of the cam
profile in cartesian coordinates both in polar coordinates. |
|
|
Is carried out the drawing of the cam profile in
dxf format for easier processing by the machine of realization. |
|
| In addition to the performance it is fundamental
to have the necessary guarantees of reliability in relation to the specific requirements,
for this PROFESSIONAL CAM in addition to the information generated on the permeability of
the lift law and on the feasibility of the cam, make a series of
calculations necessary to know the right operation. |
RELIABILITY
calculate the conditions of valve float, wear, lubrication, friction for the
right operation 
|
|
|
By entering data of the masses of the valve train system
elements, calculates the inertia forces that must be overcome by the
system to avoid valve float. |
|
|
Through the only geometric data of the springs are calculated automatically load curves that the springs can offer as opposed
inertia. |
|
|
Are calculated at each angle the
lubrication parameters and the hertzian pressure to evaluate the wear and the
duration of the cam. |
|
|
Lift laws very aggressive allows increases in permeability
for the benefit of performance, but often this determines a big mechanical loss, above all
at the high speed. For this are calculated the torque and the power
necessary to move the single cam and the whole camshaft. |
|
EASY TO USE
intuitive even for those who have little familiarity with your computer |
All the features described are easily
usable in the software PROFESSIONAL CAM which combines to the traditional
data entry, drawings and graphs to have an immediate idea of what you must enter and to
have the practical information to continue fast the development of cams. |
