Electro-hydraulic servo durability test bench for sound barrier fatigue testing machine

The noise barrier fatigue testing machine is mainly used for the fatigue test of highway, railway, overhead inserted metal noise barrier, embedded channel, etc., which can detect the ultimate fatigue life of the specimen. The main engine applies a test force to the noise barrier or embedded channel by hydraulic loading, and the test force is measured by the sensor, and the data is collected by the measurement and control card. The test force and test curve are displayed on the computer screen. Suitable for sound barrier manufacturers, quality inspection stations and other quality inspection and scientific research.
