  • Consideration of trigger signal of revolution for sophisticated gear

説明

<p>We measure trigger signal to estimate gear excitation force. Since the trigger signal has time delay, we can't estimate gear excitation force precisely. We consider characteristics of trigger sensors and how to measure the signals. We compared phase delay of trigger sensors and proposed a way to measure a trigger signal with less phase delay. In this paper, we used electromagnetic pickup, photointerrupter and hole device as a trigger sensor. We estimated phase delay of these sensors comparing with gear vibration. Photointerrupter and hole device had less phase delay than electromagnetic pickup. Photointerrupter and hole device had most of the same phase delay. But phototointerrupter had slightly small phase delay.</p>
