A Research of Vibration Signal Processing of Air Suspension System

Abstract:

Wavelet transform was utilized in vibrant signal processing of air suspension system. A dynamic model of 1/4 engineering vehicle with air suspension system was established. Road surface signal of B grade was input to the dynamic model. Vibrant acceleration curve of under spring mass and dynamic load curve of air suspension was gained. Noise signal of under spring mass acceleration and dynamic load of air suspension system were filtrated by wavelet decomposition. Vibrant acceleration signal of under spring mass and dynamic load signal of air suspension were extracted by wavelet reconstruction. It can provide a theoretical foundation for identifying dynamic load of air suspension system.
