| 摘要 |
<p>The invention relates to an hydraulic circuit comprising an hydraulic machine (2) and receptors (4) connected by pipelines, said machine generating pressure oscillations in the circuit (1) according to a range of excitation frequencies, characterised in that said circuit comprises two variants (14, 16) of different lengths or volumes, providing different modal responses to the excitation frequencies, and controlled means (10, 12) which allow either one or the other (14, 16) of said variants to be implemented.</p> |
