摘      要：正A parametric model for the dynamics of an adjustable linear oil damper equipped in advanced rail vehicles is developed in this paper. Instantaneous leakage flows, oil compressibility, oil temperature and valve dynamics etc. are taken into account in the modelling process. A computer package based on the model is developed in MATLAB environment and numerical analyses are carried out on the damping performance by means of parameters identification. Experiments with a CAT rig are done at last and satisfied agreement is achieved between the numerical prediction and experiments.
