| 摘 要： | 0INTRODUCTIONActivedamping suspension systems mainly take the quantified value of ride comfort and vehicle handling as a performance index,in which the damping coefficient of suspension is adjusted to optimize the performance index according to the road roughness and vehicle load.An ideal scheme of active damping control is to realtimely regulate the damping coefficient according to the vehicle run states,but which is difficulty in practice［1，2］.On one hand,the road disturbance is a…

| Abstract: | A statistic linearization analysis method of bad nolinear hydraulic active damping suspension is provided.Also the optimum control strategy of semi active suspension and graded control strategy based on it are puted forward.Experimental researches are carried out on a 2 DOF(degree of freedom) hydraulic active damping suspension test system.The results showed that an excellent control effectiveness could be obtained by using statistic linearization optimum control which unfortunely requests continuously regulationg the damp in an accurate way and costs much in engeering application.On the contrary,the results also showed that graded control is more practicable which has a control effectiveness close to the optimum control and costs less. |
