HTM high-speed testing machines from 25 to 160 kN

Among other factors, the fracture behavior of many materials is dependent on the loading rate. Numerical calculation of crash safety requires relevant data and constitutive equations. Zwick's HTM servo-hydraulic high-speed testing machines allow strain-rate-dependent characteristic values to be determined over a wide speed range.

Key advantages and features

Particular uses for HTM high-speed testing machines include high-speed puncture, tensile, peel, and shear tests at high speeds. Crash tests on components can also be performed in conjunction with the optional T-slotted platform.

HTM testing machines form a complete system with all components - including the hydraulic power pack, test frame with high-speed testing actuator and safety housing, fast measurement and control electronics with PC and evaluation software - matched and integrated.

Description

  • Available in various versions with maximum test loads of 25, 50, 80 or 160 kN.
  • Maximum piston-speed 20 m/sec. For testing this can be varied over a wide range from very slow to maximum speed.
  • Can be supplied for 280 bar system pressure.
  • testControl measurement and control electronics plus testXpert II testing software enable comprehensive test result evaluation, report creation and data management.

Advantages & features

  • With testXpert a uniform software platform is available, from test definition right through to evaluation.
  • Easy integration of optical extensometers.
  • Machine is mounted on pneumatic springs, allowing installation almost anywhere.
