Gear and Transmission Noise Measurement System
Mission Noise Test System
This measurement system measures gear noise using acceleration sensors and microphones to detect vibrations and noises generated from the gear on a Mission Line tester, and determines the quality of the product.
The front-end for measurement uses a RION SA-02 multi-channel analysis processor and communicates with the transmission control system (sequencer) via RS-232C.
Measurement begins with a start signal from the transmission test machine's control panel. The system performs rotational increase/decrease and steady-state testing for each gear, and the measured vibrations are analyzed using FFT to calculate the power spectrum and order, thereby determining the gear noise.
Separate Furthermore, judgments can also be made using the MTA method, POA (Partial Overall), and wave crest factor calculation.
- Control Mode: Steady-state, Acceleration, Deceleration Tracking
- Judgment Method: Power Spectrum Judgment Window, POA, Wave Crest Factor Judgment
- Judgment in Tracking Analysis: Up to 8 order judgment lines can be set
- Spectrum Map Display during Tracking
- Judgment Threshold Setting: NG/YELLOW can be set
