Chassistech - Race Car Chassis Dynamics Analysis
DTMPower offers a suspension dynamics assessment and design service called
“Chassistech".
This entails a full survey of the vehicles' suspension system, measurements are taken and a schematic CAD drawing of the suspension is produced. This will show the front and rear roll centres, virtual swing axle lengths, scrub radii, and spring, damper, and anti-roll bar movement ratios.
A number of other measurements, weights and data are taken and used in our bespoke computer program to give a number of resultant suspension parameters, including:
- dynamic weight distribution
- anti-roll bar roll resistances
- total roll resistance
- roll angle
- wheel frequencies and rates
From this data it is possible to predict the handling characteristics of the vehicle, and then more importantly, make the necessary changes to the roll centres, virtual swing axle lengths, spring rates and anti-roll bar rates, to optimise the handling.
The final report will detail all the necessary changes in suspension pivot point locations, required spring rates, and the dimensions and specification of material for the fabrication of revised anti-roll bars. This will achieve the optimum handling performance from the car. This report will of course take into account other design parameters such as; driver ability, tyre size and performance, and technical regulations controlling the category in which the car is raced, or whether it is for fast road use.
It is possible to undertake this survey at almost any point in the construction or running of the car.
The cost of this service is £700 plus vat. Plus travel expenses. Attendance at a test or race day is charged at £280 per day plus expenses plus VAT.
