The first calculations
carried out by the software allow the static behavior of the suspensions
to be analysed
FRONT SUSPENSION
The behavior of the fork is linked to the features of the spring, or the
air chamber, present in the fork. The software calculates based on the
data entered
FORCE DEVELOPED BY THE FORK AS A FUNCTION OF THE MOVEMENT
and if the fork has both a spring
and an air chamber, that work in parallel, it also shows the
respective components
SPRING FORCE AS A FUNCTION OF THE MOVEMENT
AIR FORCE AS A FUNCTION OF THE MOVEMENT
if in addition to the features of
the fork, it's also entered the angle that it forms with the
chassis, it is calculated
WHEEL MOVEMENT IN FUNCTION OF THE VERTICAL LOAD APPLIED
REAR SUSPENSION
The rear suspension is not direct, but has a kinematic mechanism that
transmits the force from the wheel to the shock absorber.
One of the most important features of the software Suspension Design is
to calculate the behavior of the kinematic mechanism, which is
fundamental to understanding how the suspension will work in the
different operating conditions.
Based on the geometric data of the kinematic mechanism, the software
calculates:
SHOCK MOVEMENT IN FUNCTION OF WHEEL MOVEMENT
SHOCK FORCE / WHEEL FORCE RATIO IN FUNCTION OF THE WHEEL MOVEMENT
WHEEL CENTER POSITION RELATIVE TO THE SWING ARM PIVOT
In addition to the graphs, the software shows an animation of the
suspension operation, with all the significant quantities highlighted in
real time:
These calculations are very
important because during the design or development phase of the
suspension, it is easy to see how by modifying the dimensions of the
linkages of the kinematics, or the length of the shock absorber, the
behavior of the suspension can be varied.
If the features of the shock absorber and transmission are entered, the
software then calculates:
WHEEL MOVEMENT IN FUNCTION OF THE VERTICAL LOAD APPLIED
WHEEL MOVEMENT IN ACCELERATION PHASE FOR CHAIN FORCE EFFECT AND WEIGHT TRANSFER
The effect of the chain force is extremely important because it
influences the motorbike balance (squat), for this reason the software
is very useful in the development or design phase of the suspension, to
optimize this aspect too:
