Hydraulic Vibration Shaker
Electro-hydraulic vibration table is the abbreviation of electronic hydraulic vibration table. Electro-hydraulic servo vibration has the advantages of fast response speed, high anti-load rigidity, flexible control mode, etc. Its exciting force can reach hundreds of thousands of newtons, and large displacement amplitudes can be obtained, and the maximum displacement can reach more than 2 meters. The structure is small but firm, and is able to withstand horizontal load.
Electro-hydraulic servo vibration is a control system that uses hydraulic power components as actuators, according to the principle of closed-loop feedback, which makes the output of the system track a given signal, and can transform and amplify the input.
It is suitable for testing all kinds of products in aviation, marine, automotive, earthquake and other industries.
HV Hydraulic Vibration Shaker
-
HV series hydraulic vibration shaker converts the energy of high-pressure liquid into the power of the reciprocating motion of the cylinder through the electro-hydraulic servo valve. Especially suitable for vibration tests requiring low frequency and high force. It can realize sine, random, multi-point excitation and shock test (sine, random, sine on random, random on random, or resonant search & dwell). It’s applied for reproducing the vibrations of transportation vehicles, bulk packaging products, machinery, electrical and electronic products in the actual environment, thereby optimizing the product structure and saving costs.
To achieve sine vibration, random vibration, multi-point excitation, and shock and bump.
It can be used to simulate seismic excitation with low frequency and high force features.
The high-strength cast aluminum or cast magnesium table ensures uniform and consistent vibration, high reproducibility, and avoids deformation of the table.
