Hello everyone,
I am Ritwik Das from BITS Pilani,India.Our team ran a Pushrod and Rocker system for their last car. However this year we are considering to use a direct acting spring damper system. The reasons to consider so are as follows:
1.Low Weight
2.Less Complexity
3.More Testing Time
4.Bellcrank geometries are not usually changed very often to give different wheel rates.
5.Multiple shock pick up points may be used to give adjustability instead.
6.No significant aero drag on an FSAE car.
We have spring dampers that we have used for the last car. I need to determine whether these will be suitable for the direct acting setup.
What I know & what I have
The force and velocity curves specified by the manufacturer ,so my guess is that the damper shock forces seen in the curve should be less than we would face when the spring is directly mounted.I am also attaching the calculations used for determining spring rates and force velocity curves which were used last year.
We currently have the Quarter Midget Series Damper from KAZ Technologies. This is the link
