Electro-Hydraulic Actuation
The electro-hydraulic loading system is designed for testing various objects with specified parameters and high accuracy.
FPGA allows implementing precision control for multi-connected loading systems.
The quality and degree of automation affects the testing time and increases the accuracy of measurement and parameter representation.
The implementation of the protection loop on the FPGA allows achieving a high speed response of the security system to ensure the safety of the test object.
feedback is realised by:
  • Pressure
  • Force
  • Displacement
  • Speed
  • Acceleration
  • Stress strain behaviour
