SIGNAL PROCESSING SYSTEM FOR ENERGY TRANSFER ARRANGEMENT UNDER TEST

摘要

Processes and apparatus for signal analysis enable "pass/fail" determinations to be made with respect to noisiness of a mechanical system under test, particularly the presence of bumps and nicks in gear train systems under test. In a process aspect, for a gear system, a torque input is applied. A first signal responsive to the noise of the gear system under test is produced, which is converted to digital data responsive to a first correlation between the first signal and time. Peaks in the digital data are measured to determine whether they exceed a predetermined threshold magnitude. The peaks that exceed the predetermined threshold magnitude are subjected to harmonic analysis, the results being compared to gear tooth harmonics to determine whether the peaks constitute an anomaly. A load is applied to the gear system under test, the load being controllable in response to the noise signals.
