Control Cube Servo Controller and Cubus Software

Fatigue and fatigue strength testing - with maximum flexibility and efficiency.
Servoregler Control Cube und Software Cubus

Servo-hydraulic testing systems are the preferred option for fatigue and fatigue strength tests. The performance of these systems is determined to a large degree by the measurement and control electronics used, together with the associated testing software. The Control Cube servo controller and Cubus testing software are ideal both for new testing systems and for retrofitting to existing servo-hydraulic testing systems, as well as for multiaxial applications.
This system was developed by ZwickRoell in collaboration with CaTs3 (Consultants in Automated Test & Structural-dynamic Simulation Systems). The company's long-standing experience and expertise are reflected in a highly efficient product capable of handling customers' constantly expanding needs while at the same time meeting ZwickRoell's high safety and quality standards.
During development, special attention was paid to achieving a high degree of testing system flexibility and expandability. Impressive features of the Cubus software platform include outstanding versatility and an extremely user-friendly operating concept, especially when faced with frequently changing testing requirements. From configuration of the test bench to routine cyclic tests to advanced applications - there is a Cubus test program to suit all. For simulation of actual service loads QanTiM iteration® software is optionally available.

The Technical University of Munich relies on ZwickRoell for fatigue testing

The Institute of Machine Elements of the Technical University of Munich, also known as the Gear Research Center (FZG), is today’s leading international research institute for gears and transmissions. The focus of the institute’s research activities is the development of methods and tools for reliable determination of fatigue life, efficiency, and vibration characteristics of these components. To meet the requirements of future research projects, several servohydraulic test stands were modernized by ZwickRoell.
