WPM Leipzig · Technical Information Control System and User Interface A digital control system for dynamic testing is used as a container version with a laptop. The control and evaluation software implements the specified frequency and displacement amplitude of the mass vibration, measures the generated displacement and force amplitudes and represents the vibration diagrams of the hydraulic piston of test cylinder. The control system can be used in the following control modes: • Force control • Position control • Strain control During the experiment, the smooth switchover between the control...
