'Discovery consists of seeing what everyone else has seen, and thinking what no one else has thought'

摘要

1. New sensor designed to accentuate base strain from ball pass 2. Outputs both acceleration and ball pass strain (BPS) signals 3. Ball pass strain then used to enhance acceleration 1. Accentuates events related to bearing defects? Noise reduction including other impulsive events (non-coherent) 2. Identification of defective component? Outer race directly by bal! pass (bpfo) - inner race (and others) via scaling 3. Accentuates the Point of Entry? Low energy event, otherwise difficult to detect (c.f. impact).
