I Reprogramed a Quasistatic Test Stand
Using a Dewesoft Sirius DAQ module, an outdated piece of equipment was revived!
It was originally programmed with a plc controller and dedicated PC, the goal was to be able to control the fixture using a DEWESoft Sirius Data Aquisition module while be able to record data from a load cell, 4 triaxial accelerometers, and a camera, while controlling positional accuracy to 40 thousands of an inch.
Three string pots were used to provide positional data of the hydraulic ram. A PID was programmed to extend the arm at a certain rate to a given distance. The Piston was required to be repeatable to a tenth of an inch.
Most all of the programming was done inside the DEWESoft enviroment using some C++ code for the PID.
A Graphical Interface was provided to control the unit and show and record data.
