Urethane Shock Absorber Production Testing
The Challenge:
Developing a data acquisition and control system for a hydraulic press used to test railroad car shock absorbers. The system must retain three months of historical data and provide an easy method to download from the controller. The shock absorbers are cylindrical urethane molds of 5 inches in height and 3 3/8 inches in diameter. One is placed on each corner of rail car frame that transports rail car shipping containers. After the urethane absorbers are produced they need to be tested by applying a typical load to them to ensure they absorb the appropriate amount of force.
The Solution:
Developing a LabVIEW RealTime application deployed to a National Instruments Compact Fieldpoint (cFP) controller and displays a user interface through a web browser remote panel. The application would also log test data to a comma separated value (.csv) file which would be easily retrievable thru the conveniently built-in FTP server on the cFP controller.
