HIGHLIGHTS
  • The possibility of limiting the maximum dynamic load during the start-up process observed.
  • A dynamic model of a hydrostatic drive equipped with an accumulator was developed.
  • The influence of the accumulator on the sound pressure level was analysed.
  • With accumulator capacity increases -value of the dynamic excess coefficient decreases.
  • Acoustic tests were carried out for a system with a linear hydrostatic drive simulator.

ABSTRACT
The article presents the possibility of influencing the hydrostatic drive's dynamics and noise using a hydropneumatics accumulator. The possibility of limiting the maximum dynamic load during the start-up period of a drive equipped with an accumulator and controlled by a slide distributor is presented in the article. The influence of the accumulator on the sound pressure level and its relationship with the maximum dynamic values of the working fluid pressure in the hydraulic system is also described. Experimental studies of the dynamics and acoustics of laboratory hydrostatic systems were performed. A dynamic model of the hydrostatic drive equipped with an accumulator was developed, which was used to perform simulation tests illustrating the impact of the accumulator capacity on the system's dynamics. Acoustic tests were carried out for a system with a linear hydrostatic drive simulator.
