High strain rates and crash simulation
The HTM series servohydraulic high-speed testing machines allow you to determine strain-rate-dependent characteristic values over a wide speed range. Uses for machine include puncture tests and high-speed tensile tests, as well as peel, and shear tests at high speeds. Crash tests on components can also be performed in conjunction with the optional T-slotted platform.
The HTM series is available in various versions with maximum test loads of 25 kN, 50 kN, 80 kN or 160 kN.
The fracture behavior of many materials is dependent on, among other things, the loading rate. Relevant data and constitutive equations are required for the numerical calculation of crash safety. With a maximum piston speed of 20 m/sec, high-speed testing machines can be used for crash simulation. For testing, the speed can be selected from a wide range, starting very slow and going up to maximum speed.
High-speed 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 testControl measurement and control electronics with PC and testXpert testing software—perfectly coordinated and integrated.

Common Tests
Particular uses for HTM high-speed testing machines include puncture tests and high-speed tensile tests, as well as peel and shear tests at high test speeds. They are ideally suited for the determination of the material behavior under crash loading. Their maximum piston speed of 20 m/s (72 km/h) is faster than the 64 km/h test speed used in the Euro NCAP frontal impact crash test.
