Shock absorbers are chosen according to a certain average influence, so in a wider range of an influence of vibrations as well as on changes of the weight of the transported cargo a scantiness of ordinary shock absorbers comes to light. In the article, possibilities of an application of a shock absorber with magnetic liquid are discussed. In such case, dissipative features may be changed dependently on the level on vibrations of the amortized object. For this purpose, a feedback receiving signals from a seismic sensor is used. Vibration isolating features for the case when the signal is integrated for one or two times are described. In case of feedback according to the offset, i.e. when the signal of the accelerometer is integrated for two times, the efficiency of the vibration isolating system becomes independent on changes of the amortized mass.
