Rookie looking for advice with Labview for a Dynomometer
(OP)
We are looking to build a dyno for a custom application and considering the use of Labview as the software. I have a friend that has Labview but rarely uses it or knows much about it. I am willing to get a seat if it will do what we need.
For now, all we need to do is bring in approx 12 channels of data and create graphs to compare data as well as view real time data. later, we will want to better automate the system to operate the braking portion and throttle in a closed loop system where we command variables and allow the software to run the system. I am not sure if outputs are anything that Labview can even do.
I have never turned a page with Labview so really wondering how intuitive it really is and if there are better packages out there for what we want to do. I am also open to open source type programs that may be real close to what we need and tweak from there. Nothing set in stone on the software side.
On the hardware, we we will have several analog sensors inputting to a DAQ card and then back to the PC. The question was raised whether we will have to have signal conditioning before the DAQ card. I honestly cannot answer just yet. We have not selected the DAQ card either.

I had to assemble a motor duynomometer in a very short space of time and LabVIEW proved invaluable. It was all done on a tight budget using USB based interfaces with analogue measurements, an analogue out, CAN and CANopen interfaces for control of the test motor and the drive motor.
The big advantage for me has been the ease with which I can add features such as control loops, different displays etc.
I would also agree that National Instruments customer support has been excellent.
