摘要:
利用弦的谐振原理,通过光电检测方法,我们试制了微振动检测仪,用它来精确测定直径为0.1mm的丝的转速(高达80万转/分),初步解决了弹力丝捻度的动态检测。
Abstract:
Based upon the principle of mechanical resonence of a string, we have designed and produced a photoelectric detector for micro-vibration signal, by means of which it is possible to measure accurately the speed of rotation up to 800,000 rpm of a filament 0.1mm in diameter, thereby answering the purpose of active detection of the twist of textured yarn.
