OF VIBRATIONS IN HYDRAULICALLY POWERED SUPPORTS

Two approaches to investigation of hydroelastic shock 
absorbers ensuring an efficient decrease in vibrations and noise in 
mobile machines have been presented. It has been shown that the parameters 
obtained by the method of amplitude-frequency characteristics more 
accurately correspond to the parameters of the physical model than 
the data computed with the impedance method.
