Abstract
Material testing devices are used in laboratory and industrial environments for testing and research in fracture mechanics and are typically operated by servo-hydraulic or servo-pneumatic actuators. They contain an increasing number of electronic and microprocessor-controlled components, with which they achieve appropriate dynamics and the ability to store and process signals.
The paper presents the development, implementation and operation of a flexible device for testing the dynamic strength of materials based on linear electro-hydraulic servo drive with closed loop force control. To control the components, a Beckhoff multi-core controller is used, which simultaneously runs a control program with real time force control, as well as a human-machine interface in the Windows environment. The presented device is capable of achieving forces up to 40 kN at test speeds up to 20 Hz.
