The pre-filer solves the problem that the used wind generated by adopting the prior art has the disadvantages of low purified degree, so that the mechanical jamming is generated in the turnover. 它解决了现有技术所存在的用风纯洁度不高,导致道岔产生机械卡阻的缺陷。
Data Processing of valve vibration is investigated major in low-frequency current component and high-frequency mechanical jamming component. 本文讨论了实测气门加速度信号中低频的趋势分量和高频机械振动干扰的处理方法。
