A race lap was recorded with strain gauges applied to the different elements of the rear wheel suspension. A macro was written in order to calculate the applied force at the wheel contact point with road surface starting from strain gauges signals. The three time history forces profile, Fx, Fy, Fz were imported as user defined forces profile into the RTC-9000 test controller and applied by the actuators. The RTC 9000 test controller is engineered in Italy by EnginLAB srl using cutting edge real time FPGA technology by National Instruments.
