doi:10.3901/JME.2025.08.344

Abstract

Abstract: The Switching characteristics of digital valve package caused the low-frequency pressure pulsation in the digital hydraulic system, However, the current traditional pressure pulsation attenuation structure is suitable for the high-frequency pulsation. Thus, A pressure pulsation attenuation structure is propsed, which combines the flexible lining with the principle of reverse phase cancellation of pressure wave of to realize double filterin. Firstly, The mathematical model of transmission matrix is established by one-dimensional analytical method and electro-hydraulic comparison method, the influence of key structural parameters such as the bulk modulus of the flexible lining, neck diameter, and HQ tube on the attenuation effect of low-frequency pressure pulsation is analyzed based on Matlab numerical simulation. Secondly, the prototype structural parameters were designed by matching the low-frequency pressure pulsation of digital valve package. Finally, the tests are conducted on its test bench to verify the attenuation effect of low-frequency pressure pulsation. The test results show that the proposed compound pressure pulsation structure had an average insertion loss of more than 5 dB in the frequency band of 10-50 Hz and 85-100 Hz, and the maximum test value could reach 11.95 dB. The research results provide theoretical support and analytical methods for the design of low-frequency pressure pulsation structures.
