railwayRubber pad dynamic and static stiffness fatigue testing machinecore purpose

Measuring static stiffness: force under static load-Displacement curve and stiffness value.

Measurement of dynamic stiffness: complex stiffness under dynamic alternating loads (including dynamic stiffness, damping coefficient, and loss angle).

Conduct fatigue durability tests: simulate actual working conditions and perform over a million cycles of loading to evaluate the lifespan.

Adaptation: Railway rubber pads, automotive suspensions, building vibration isolation pads, ship shock absorbers, etc.

main structure

Host frame: Dual column/Four column high rigidity structure ensures dynamic loading stability.

Loading system: Electro hydraulic servo actuator (core), providing dynamic force and displacement output.

Measurement and Control System:

Force sensor (spoke type)/Column type, precision0.5%–1% FS）.

Displacement sensor (magnetostrictive)/Grating, resolution0.001mm）.

all-digitalDSPServo controller, closed-loop control.

Hydraulic source/Electric cylinder: Provides power, and the electric cylinder type is more suitable for small and medium load, low-noise scenarios.

Experimental software: Real time collection, calculation, and report generation, supporting multiple waveforms and custom programs.
