The electronic universal testing machine mainly uses an electro-hydraulic servo motor as a power source, and uses a screw rod and a screw nut as the execution components, thereby achieving speed control of the mobile beam.
The future development direction of electro-hydraulic servo control systems is in the field of high voltage and high power. The purpose of high pressure is mainly to reduce the weight and structural size of the system. For example, the cylinder pressure is high, the piston area can be smaller, and the load flow can also be smaller, so the volume and weight of the energy and power mechanism can be reduced; high power is to solve the drag problem of large inertia and heavy load. Electronic universal testing machine strives to achieve high power, high efficiency, low cost, small energy consumption, small size and light weight
