Vibration Isolation Performance Research of Commercial Truck’s Cab Suspension System Based on Road Load Data
2015
Based on road load data of commercial truck’s cab suspension system, extreme value and standard deviation of acceleration signals are statistically analyzed. And then, pseudo-damage analysis is done to get the damage attenuation level of the shock absorber. According to the theory of shock absorber vibration isolation, amplitude frequency response characteristics of the cab suspension system are acquired. Significance of the study is to find a way to evaluate the performance of commercial truck’s cab suspension system. It is very useful to guide the forward design of cab suspension system from the perspective of passenger comfort and component fatigue life so that it can provide data support and improvement suggestions for the development of commercial truck cab suspension system.
