This chapter describes how all dimensions which an engineer ought to know like the position of the centre of gravity in three directions, wheel loads, moment of inertia, camber, caster, track, KPI, motion ratio, aerodynamic drag etc.—can be measured and calculated. These dimensions will be discussed throughout the book. The ultimate goal in racing is the continuousContinuous speed improvement of lap times. However, before optimisation approaches with regard to driving dynamics can be used at all, first and foremost information on the current “setup” is vital, i.e. knowing the. • weight distribution and dimensions. • current setting values of the suspension. • aerodynamicAerodynamic adjustment parameters. All in all, these parameters have the essential, decisive influence on the success of lap times—over and above the tyreTyre properties (see Chap. 3) and engine/transmissionTransmission characteristics. Only through establishing this starting point—on the basis of driver feedback and/or data recording—can reliable optimisation be executed later on. The settings to be determined initially thus offer important indications of the basic tuning of the vehicle. The subsequent verification of the final, optimised setupSetup is still done individually at the racetrack through numerous test drives (possibly with the additional support of simulationSimulation tools, see Chap. 10). In the following, the experimental determination of all relevant vehicle-specific parameters are described, which allow an assessment of the longitudinal and lateral dynamics. (source (Pütz and Serné in Handbuch Rennwagentechnik., 2019): Handbuch Rennwagentechnik). Practice has shown that, when setupSetup settings are changed, these are better being controlled by a second person (“four-eyes principle”).
