Using the GP1 to identify when undesirable handling occurs

The GP1 is an ideal instrument for monitoring the handling of assemblies during the manufacturing and delivery process. Manufacturers are realizing that incidents of undesirable handling are a major cause for shortened service life. The GP1 is a 3-axis instrument that measures: acceleration profiles, response periods, vibrations, and reactions to input. The GP1 captures, quantifies, and helps the user understand those elements that are not readily observable. Recording and understanding how an assembly was handled is an essential element for identifying possible internal damage.

The GP1 makes it easy to discover and record dynamic handling information and features an internal processor that can be set up to record summary and/or detail type information

The summary information mode is easy-to-understand and gives the user pertinent information without unnecessary detail. This mode automatically calculates and reports: when the motion occurred, what type of motion it was, what the thresholds were and how long the motion lasted. The summary mode has pre-programmed reports that identify drops, tilts, impacts and heavy landings. In the following example a GP1 records a 2" drop, a 4" drop, a 10" drop and a 20" drop (plus a bounce).

The GP1's summary mode can calculate and report up to 21 different measurements, these measurements take the guesswork out of trying to understand what occurred.

In addition to the calculated values that are generated by the summary mode, the GP1 also records acceleration waveforms; acceleration waveforms are a compilation of individual acceleration samples taken every 10 milliseconds and then stitched together to describe the characteristics of the motion. The waveform files show the details and nuances of the motion and displays exactly what occurred, the ability to visualize dynamic signatures helps the user see and compare complex relationships. In this example a heavy landing has been recorded, the data also shows significant y-axis input, which indicates that the assembly also rotated during the event.

The software that comes with the GP1 has an export to csv function that lets the user export the summary and detail data out to other analysis packages.

The GP1 offers an easy way to capture and understand dynamic handling, understanding dynamic handling gives the user a vital piece of information for assessing the possibility of hidden damage or shortened service life.
