Feature: Automotive
The software allows the engineer to take surface runout and thickness variation measurements in situ before and after each test run, without dismounting the wheel, which influences the results
the results. In addition, a custom 4-channel sensor has been developed that allows the measurement of the vehicle’s full braking cycle, with four tracks at once on each side of the brake disc. Both single-point infrared temperature
sensors and thermal cameras from our thermoMETER and thermoIMAGER product ranges are also being used for brake-temperature testing in vehicle development.
Crash tests, spring and pedal travel Draw-wire sensors are also readily found in road and crash tests and simulators, where they must meet the highest requirements in terms of wire acceleration, vibration, shock and installation space. For example, with a measuring range of 40mm and possible cable acceleration to 60g, Micro-Epsilon’s wireSENSOR MT19 is particularly suitable for applications that require high dynamics, such as vehicle crash test dummies, simulators and impact test rigs. In spring travel measurements, MPM
draw-wire displacement sensors are typically mounted in parallel with the shock absorber, to record the data under different road conditions. Based on the resultant displacement signal, vibration velocity and vibration acceleration can easily be determined. In crash tests, multiple MPM draw-wire sensors measure
