The intermittent suction can also supply larger lift force but fluctuation of lift force is found. 间歇式吸气也可提高平均升力,但引起升力的波动。
Results show that the ice-induced vibration of a flexible structure is a kind of intermittent free-damped vibration after a forced vibration, dominated by modes of low frequencies, and frequency components of the ice force are abundant. 实验结果表明,冰激柔性锥体振动是一种以低频振动为主、间歇性的随机受迫振动和自由阻尼振动,作用于锥体上的动冰力频率成分丰富。
To judge the transition from dispersed bubble to intermittent flow pattern in horizontal wellbore by force analyzing of dispersed bubble; 通过对分散气泡进行受力分析,得到水平井筒分散泡状流向间歇流流型转变的判别方法;
The mechanism of milling process is very complex due to occurrence of the periodical and intermittent cutting process, semi-closed-form machining and chip thickness variation. The periodical cutting force excites vibration between the cutter and workpiece. 由于铣削加工过程中的多刃断续切削、半封闭加工以及切削厚度随时间改变等特性,使得铣削加工机理较为复杂,加工过程容易出现颤振现象。
Granite profiled surface processing is intermittent grinding, the grinding force fluctuates greatly, the dynamic characteristics have a fractal law. 花岗石异型面的加工属于断续磨削加工,其磨削力大小变化很大,其动态特性具有分形规律。
