A nonparametric method to model hydraulic damper based on support vector regression
A nonparametric method to model hydraulic damper based on support vector regression is developed.Dynamometer measurements of a damper are used to train and test the models.After the models have been developed,we investigate the relationship between the damper force and the damper states (including displacement,velocity and acceleration).The results show three conclusions: firstly,the damper force of this damper is dominantly a function of velocity;secondly,this damper is displacement-related due to the compressibility of the oil and the gas;finally,the damper force is acceleration-related only at high velocity.Afterwards,we predict the strongly nonlinear characteristics of this damper when the maximum velocities of the sine inputs are higher than 1 m s-1 The predict result is compatible with the experimental measurements very well.
