Title: Inertial system for measurement of the dynamic response and status of the vehicle suspension elements
Keywords: MEMS sensor, diagnosis, dynamic response
Abstract: The current paper describes the information and communication system, based on micromechanical inertial sensors (MEMS) to measure the dynamic response and status of the vehicle suspension elements. It consists of an inertial sensor network from at least two sensors, which are situated on the moving elements of the vehicle suspension. The communication system part reads and stores the inertial sensor data while the information system part calculates the frequency response, attenuation time, resonance frequencies and distance between moving parts. The calculated distance is compared with the adjusted clearance and the system accuracy is shown. It is shown that the system is capable to measure the distances from 0.6 to 1.0mm with 0.1mm accuracy. The inertial data scanning is performed with a sampling frequency of 160Hz, according to the expected peak accelerations and translations.
