An Experimental Study on Hydrokinetic Characteristics of Oil Damping Structure

The experimental study of oil-damping mechanism in multi-nonlinear coupling vibration insulation system is carried out in this paper.The input and output data of absolute acceleration of oil-damping structure in a wide frequency ranger are tested when the condition of related parameters changes.The formula derivation of oil-damping force is done,and the oil-damping force is computed.Using the method of range analysis,the different effects of structural and physical parameters on oil-damping force are studied.Furthermore,the rule of oil-damping force with influence of structural and physical parameters is also studied.The results of experimental study suggest that the oil-damping force is related to the structural and physical parameters of the absorber,and it shows a strong regularity.These works lay an experimental base for the future research.
