Is it possible to do a closed loop control of a sine wave?

An analogue voltage sine wave signal is send from a PLC to a Piezo actuator. This actuator converts the voltage to force. A load cell checks what the applied force is and sends a mA-signal...

What should my boundary conditions be in abaqus and how do I apply a sine load?

I want to model a T bone specimen that is subjected to a sine load. The specimen is clamped in as showed on the figure. I was wondering what I should chose as boundary conditions and how I can...

How can you clamp thin steel sheets for a fatigue test?

I'm currently developing a fatigue test (tension-tension) of thin steel (T-bone) sheets (0.2-0.5mm thickness). The clamping of the specimen should be with screws to cut costs. I already found a...

What do you need to let a Piezo servo controller to communicate with a load cell (amplifier) via LabView?

I want my piezo actuator to give a sinusoidal load as output and thus keep the forces (max, min and mean) constant. To do this I need a close loop control with a load cell I think. However the...

How do you convert displacement controlled to load controlled?

I have a piezo actuator for a micro fatigue test which should give a sinusoidal load output. But I don't know how you go from displacement controlled to load controlled with the actuator. The...
