SELECTED ADVERSE OPERATIONAL EFFECTS OF HYDROSTATIC SYSTEMS

: This paper discusses the operational and environmental aspects of hydrostatic systems. Requirements which such systems must meet and criteria for evaluating the latter are specified. The noisiness of operation of hydrostatic systems and the reduction of their environmental impact have become new major criteria. The interrelationship between pressure pulsations, mechanical vibrations and the noise (especially low-frequency noise) emitted to the environment is identified. Possible effective passive and active ways of reducing the adverse impact of hydrostatic systems are indicated.
