The main machine adopts underneath type of oil cylinder, tensile space is above the main machine, compression and bending space is
between the lower cross beam and working station.
It adopts transmission mechanism of worm gear traversing movable cross-beam to adjust test space, so that the drive system and positioning system are completely separated, geometric center of loading system is in full accordance with center of force, and also guaranteeing the coaxiality of upper and lower jaw and the durability of machine.
3.1 Hydraulic principle:
As shown in figure 2, it is load-adaptive meter in speed control system.
Hydraulic oil in the fuel tank enters into oil circuit when the motor drives the oil pump, it flows through non-return valve, 10μhigh-pressure filter, differential pressure valve group and servo valve to enter into oil cylinder. The computer sends out signal to the servo motor, to control the mouth and direction of servo valve, so as to control the flow entering into the oil cylinder, realizing control of uniform-speed test force and displacement.
