Design of Vibrometer Data Acquisition System for Vehicle Suspension
In view of the limited vibration suppression performance of passive suspension in the process of isolating body vibration,sensor acquisition technology can accurately feedback the collected vibration signals to the suspension vibration reduction system,so as to improve the suppression effect of suspension on road roughness.In this paper,a data acquisition system of suspension vibration sensor is developed,which integrates signal acquisition,conversion and transmission,and integrates analog circuits such as amplification,filtering and notch to complete PCB design for signal conditioning.The lower computer chip is used to complete signal processing,data visual monitoring interface and medium and long distance communication data transmission,and finally the signal compensation and analysis process-ing are completed in the upper computer.The system test shows that the system functions normally,runs stably,meets the requirements of suspension vibration monitoring,and provides an effective design method for the realization of signal acquisition,processing and communication of vehicle active control system.
