Product name	Electro hydraulic servo pseudo dynamic loading test system
Customized service	We not only provide standardized machines, but also customize machines and LOGO according to customer requirements. Please tell us your requirements and we will try our best to meet your needs.
Test standard	Please provide the test standard you need to our company, our company will help you customize the test machine that meets the test standard you need
Functions and uses of products	It is mainly used for pseudo-dynamic tests of typical structures such as columns, beams, walls, frames, nodes, etc. It can also complete multi-point synchronous and asynchronous loading of multiple actuators in a combined frame, and test typical structures under complex stress conditions The mechanical properties. It adopts computer, fully digital closed-loop controller, servo valve and force and displacement sensors to form an automatic closed-loop, tracking control force value and displacement.
