Excitation Based on Certain Type of Environment Transport Vehicles Identification of Modal Parameters

Experimental venues,transport vehicles by driving a certain type of constant velocity in dirt road driving,get 6 points of acceleration response data measured using method from cross-power spectrum of vehicles,modal frequency,damping ratio and formation were studied.Experimental Software with Dasp analyze modal parameters are compared,analysis of the data is credible,then vehicle dynamics for study and rational arrangement of goods vehicle to provide theoretical and experimental issues such as guidance.
