Summary:

In this report, the DCX Stress Lab and the Tool Development and Test Support groups investigated automating a resonant bending crankshaft fatigue test. Fatigue testing, in general, is a laborious process since many samples are needed for analysis. This makes development cost and speed dependant on the component test efficiency. In the case of crankshaft resonant bending testing, both cost and speed are influenced by the manual feedback operation needed to run the current procedure. In order to increase the efficiency of this process, this project sought to automate the following tasks: maintaining the load on the part, reacting to resonance changes in the part, mapping resonance changes, logging the number of cycles, and discerning resonance frequency shift failure modes objectively. An analog I/O frequency reader/generator controlled with control software developed by the DCX Stress Lab and the Tool Development and Test Support groups proved to run this resonance fatigue test successfully
