Special Device Tpp (twin-purpose) For Rumul Resonance Testing Machines

The arrangement of two oscillating heads working in opposite directions results in an unusually light construction for a resonance testing machine with a nominal load of 500 kN. With the double spindle arrangement, the overall height could also be kept relatively low. The clamping length is adapted to the customer's needs by means of spindle extensions.

chambers RUMUL offers a variety of customer-specific solutions to test materials at elevated temperatures

The crack length measuring system FRACTOMAT is a system that works according to the indirect potential method, which is used for the exact measurement and control of the crack length and the crack propagation in fracture mechanics samples. The various interfaces allow use in any test set-up, including any other makes of testing machine. The transducer consists of a crack length measuring film (KRAK GAGE), which is glued to the specimen in an electrically insulated manner like a strain gauge and connected to the FRACTOMAT.

The small testing machine can be used economically for vibrating small fracture mechanics samples or for quality monitoring of small parts during production. Because of the small footprint, the machine can also be used in "hot cells". With simple additions, the machine can then be operated with a manipulator.
