Rail Transit Railway Tunnel Embedded Channel Fatigue Testing Machine

Railway Tunnel Anchor Channel Bolt Fatigue Tester

Functional Parameters:

→ Fatigue characteristic testing of the channel body (TB/T3329-2013 Standard 5.5.6).

→ Fatigue characteristic testing of the 500x500mm precast concrete channel, anchor bolt, and T-bolt combination (TB/T3329-2013 Standard 5.5.7).

→ Maximum tensile load capacity of embedded channel components, vertical shear working load of single anchor stud (FJ), tensile working load of single anchor stud (FL), T-bolt load capacity, allowable sliding load test of single bolt along the axial direction of the channel, deflection test, etc.

→ Dynamic and static load ±50kN/100kN, amplitude ±75mm, frequency 0.01～15Hz.

→ Load force measurement range 2%～100%, ±0.5%.

→ T-type test bench net width >1000x670mm, test space net height 0-800mm.

→ Two-column actuator upper frame structure, high-rigidity fatigue load frame.

→ Fatigue test waveforms: sine wave, triangle wave, square wave, block wave, static loading ramp, etc.

→ Crossbeam hydraulic lifting and locking mechanism, linear servo actuator, constant pressure servo pump station.

→ Dedicated water chiller for servo pump station, used for cooling the servo pump station, no need for additional water cooling towers or pools.

→ Strong electrical control integrated with the pump station, independently placed, pump station start/stop, remote computer control.

→ HRJ fully digital hydraulic servo control system, full digital closed-loop control of force and displacement, control modes can be smoothly switched.
