Dynamic and fatigue test system
ASTM E647, ASTM E399, ASTM E-1290 Shanghai Hualong Test Instruments

PWS series are ideal for a variety of tests like tension compression flex/bend fatigue (low cycle fatigue / high cycle fatigue / fatigue crack propagation ASTM E647), fracture mechanics (K1c per ASTM E399, J1c, CTOD per ASTM E-1290), damping properties and vibration testing.
Our test systems are designed for conducting tests at ambient temperature, elevated temperature (high temperature fatigue characterization) and low temperature.

main features:
The lightweight crosshead and stiff load frame components reduce load frame deflections and increase the performance envelope of the system.
Servo valves offer high response and accurate control.
Hydraulic service manifolds with close-coupled accumulators improve the response of the actuator
Load unit stiffness and extremely low friction actuators ensure high possible test control and resolution, making these systems suitable for both dynamic and static testing applications.
Fully self -contained test system packaged for easy relocation and movement
Load frame on vibration isolators
Vibration isolators for quiet operation
Variety of add- on fixtures and transducers, all supported by single - platform packaging: self- aligning hydraulic grips, extensometers, pulsed, reversible p.d. unit, etc
Provision for elevated temperature testing with self-contained closed loop cooling
