Signal conditioning
Applying positive or negative camber to a wheel means that the tyre will be at an angle, even as the vehicle is going straight. Then, when the car goes into a corner, the resulting forces push the weight of the vehicle onto the whole tyre allowing it to go around the corner at a higher speed without losing traction. Many racing teams measure the camber by
O
hand and with separate tools, but this can be time-consuming and unreliable. When one particular racing team required technology that could connect its sensors to a piece of software to provide fast and precise testing of weight and incline, Mantracourt offered its expertise in remote monitoring technology. To solve this problem, the motor team used
inclinometer sensors and voltage transmission modules that are designed to take 0-10 V, to measure the incline at a variety of angles. To find out the weight each wheel had to tolerate, Mantracourt used the T24 wireless strain gauge transmitter module. These modules enable high accuracy wireless measurement of signals from bridge-based transducers like load cells and pressure sensors. This allowed the racing team to test track performance and make small adjustments based on the driver’s feedback. After collecting this data, the team used Mantracourt’s T24 integrated logging and viewing software to check the car’s centre of
ne way to enhance racing performance is to maximise the traction when a car turns, while ensuring stability is not lost on the straights of the track.
Wireless technology: a Winning formula
Valtteri Bottas currently holds the record for the highest speed in a Formula 1 race, hitting 231.4 mph in the 2016 Mexican Grand Prix. But what may seem like a fluke requires intensive testing before racers hit the track. Here Robert Badcock, CEO of signal conditioning and wireless telemetry specialist Mantracourt, discusses some of the challenges that motor teams face and how remote monitoring technology can help optimise a car for racing.
