An improvement design of multi-sensor test bench

Abstract

Abstract Parallelism error is researched for a three-coordinate testing bench that simulates the automotive environment to test the performance of multi-sensor. The studies showed that the parallelism error between the sensor and the magnet and the signal wheel has an effect on the experimental data. A calibration device with multiple sets of force sensor probes was designed to improve measurement accuracy. And probe measurement results were used to compensate parallelism error in several directions. Results show that this method can reduce above-mentioned error and improve the accuracy of experimental data effectively.
