II. Program description
1. Host
The main engine adopts an under-cylinder main engine, the tensile space is located above the main engine, and the compression and bending test spaceis located between the lower beam of the main engine and the workbench. which is more stable and accurate than the two-column structure in the market.

2. Transmission system
The lifting and lowering of the lower crossbeam adopts a motor driven by a reducer, a chain transmission mechanism, and a screw pair to realize the adjustment of the tension and compression space.
3. Hydraulic system
The hydraulic oil in the oil tank is driven by the motor to drive the high-pressure pump into the oil circuit, flows through the one-way valve, high pressure oil filter, differential pressure valve group, and servo valve, and enters the oil cylinder. The computer sends a control signal to the servo valve to control the opening and direction of the servo valve, thereby controlling the flow into the cylinder, and realizing the control of constant velocity test force and constant velocity displacement.
