技术概览

试验机机架的特性为具有极其高的刚性和固有谐振频率,非常高的对中精度,避免了不希望发生在试样上的弯曲现象,

描述

These 2-column load frames are designed for materials and component testing under dynamic loading in a closed force-flow. The frame is supported on vibration-isolating leveling units so that no appreciable forces are transmitted to the floor during normal operation. Where tests or environmental conditions are critical in nature, the use of optionally available air-springs is advisable; these have a natural frequency of approximately 3 - 6 Hz.

The efficiency of the testing system is enhanced by the especially high axial and lateral stiffness of the HB load frames, enabling higher frequencies and specimen deformations Moreover, high lateral forces which may occur in compression and flexure tests can be absorbed without difficulty.

The frames also feature extremely precise alignment; Following installation of the testing actuator and load cell, alignment accuracy is +0.1 mm per meter separation; at distances below 350mm the offset is constant at 0.05mm. Plane-parallelity of mounting surfaces is equal to or better than 0.03 mm per 100 mm. All fixtures and ZwickRoell load cells are mounted via flanges with centering-spigot.
