曲轴转速 meaning in English

crank shaft speed
crankshaft rotating speed
crankshaft speed
speed of crankshaft

The sampling rate of the system can reach 3704 sps , and the crank angle is 1 . 94 degree per sampling point corresponding to the crank speed of 1200r / min . in the mean time , the position signal of the piston could be collected by photo - electricity switch
本研究首先设计和实现了摩擦力采集电子电路系统，装置最大采样率可达到3704sps ，在曲轴转速为1200r / min时，对应曲柄转角1 . 94度采样点，并且可以采集用来确定活塞位置的光电开关的信号。
