Together with the characteristics of the engine you must enter those of
the transmission and of the vehicle, thereby the software Crankshaft Balance
Design will calculate the performance of the vehicle and will give you the correct information on how the choices of balance and inertia influence the overall performance, allowing you to find fastly the optimal solution.
The data that you must enter are very simple, in fact they are the
vehicle mass and the tyre radius, moreover you must enter the gears teeth number of the primary transmission,
of the gearbox and of the final transmission. The software Crankshaft
Balance Design can work also for engine with direct drive
(without gearbox), in this case you must enter only the final ratio.
In addition to these data is possible enter, if you know it, the values of inertia that have the transmission shafts and
eventuals auxiliaries applied to the crankshaft (ignition,
flywheel, etc.). Anyway the software will calculate
automatically the values of inertia of the transmission shafts
according to the gears entered, so the performance calculation
will always be realistic and effective.
At the end you must enter the shifter speed and the shifter time, in this way it will be possible to take into account the driving style and guide the choices also in according with this aspect
.
The software Crankshaft Balance Design presents another interesting feature.
In fact allows to see the effects
which would have the addition of a flywheel to the crankshaft. You
must simply enter the diameter and the thickness of the flywheel and
will be shown the inertia that offers and you will see its effect in the
results.
To assess the changes making to the engine in the phase of development
are carried out test on inertial dynamometers. These
dynamometers often aren't able to reproduce the conditions of work that
the engine has actually on the road (weight of the vehicle,
drag resistance, etc.), for this reason, could have discordances between what you see at the dyno,
and what after happens on the track. Thanks to the software Crankshaft
Balance Design you can also simulate the behavior of the
engine in the conditions created by the dynamometer and therefore to see in which
conditions work the engine at the dyno with respect to what happens
really on the road, and this can be very useful, or to understand if
the indications of the dynamometer can be totally realistic,
or to calibrate the dyno to have the same conditions of the real use of the engine.
