基于时域同步平均法的行星齿轮振动信号分离技术
Planetary Gear Signal Acquisition Technology Based on Time-Domain Synchronous Average Method
摘要
Abstract
The minimum number of turns was based on a particular planetary gear turned back to the starting point of this feature, a method of vibration signal separation technology was proposed, that was based on time-domain synchronous average. The method needed to get data faster because of short sampling time, so a right window function to extract signals was chosen. According to the characteristics of meshing signals, such as the shape of meshing signals, tooth width and its energy leak, the paper selected Tukeywin function and made sure the selected window width equal to the tooth width of the meshing signals. Time -domain synchronous average can extract complete signals of the planetary gear teeth through Tukeywin function after averaging signals. The experimental results and contrast show that this method is simple and effective.关键词
