The horizontal hydraulic vibration test bench is a kind of test bench that converts the energy of high-pressure liquid into the kinetic energy of the reciprocating motion of the actuator through the energy conversion amplifier of the electro-hydraulic servo valve, which can be used to simulate the horizontal vibration suffered by earthquakes, automobiles and parts, various buildings and steel structures, and aerospace mechanical and electrical products in the actual environment, so as to optimize the product structure. Cost savings.
