摘要
通过求解Ｕ形管中液柱运动的微分方程，分析了压力脉动幅度、脉动频率、液柱长 度、管径及液体粘度诸因素对液面波幅的影响，结果表明，在一定条件下，Ｕ形管差压计可以 用来测量内燃机进气脉动气流的平均压差。
The influences of liquid column length, pulsation frequency and viscosity on oscillation amplitude of liquid surface are aralyzed by solving the differential equation of motion for liquid column in U- tube. The results show that U -tube can be used to measure mean pressure difference for pulsating gas flow in the intake pipe of internal combustion engine under certain conditions.
