The form to design cams allows:

• to define valve lift profile, choosing it between three type of polydyne function, a trigonometric function expressly designed and a polynomial function;
• to define the ramps, choosing it between a parabolic or a cicloidal function;

The ramps and valve lift profile are automatically joined with a method to reduce the vibrations.

Choosing the type of tappet, the software calculates the cam profile analytically, this point is very important and it's performed with 1/10000 degree steps.

The software at this poin supplies:

• the cam drawing already orientated in comparison FTDC, in operation camshaft rotation and cam type (intake or exhaust);
• the minimun radius of curvature;
• the minimun diameter of tappet;
• the maximun angle of  pressure;
• the valve lift ;
• the valve velocity;
• the valve acceleration.

Other graphical visualization the software to create some files with:

• cam drawing in polar coordinate;
• cam drawing in cartesian coordinate;
• radius of curvature;
• lift;
• velocity;
• acceleration;
• contact lateral position cam-tappet;
• angle of pressure.

The form to verify valve train working allows to calculate:

• the elastic force of elicoidal springs (single or double);
• the force between cam and tappet;
• the lubrication conditions between cam and tapper;
• the hertzian pressure.

Other graphical visualization the software to create some files with:

• acceleration;
• force of inertia;
• force of spring/springs;
• total force between cam and tappet;
• lubrication parameter boundary - EHD;
• film oil tickness;
• hertzian pressure;
• hertzian contact width;
• friction force and torque.
