四、压力脉动的计算用三——(2)节所述数学模型可以计算缓冲瓶及其简单负载系统的Z_(1M)——N曲线。若已知脉动流量的规律,也可算出压力脉动P_(1M)及P_(sM)。但前述模型中只涉及三种简化的典型负载的计算,这里讨论复杂的实际负载系统的计算方法。利用这种方法理论上可以计算出各种线路上任意点的压力脉动和流量脉动值。另外,若需要计入导管管壁和某些元件壳体弹性的影响,也是可以的。
Calculation of Pressure Fluctuation The mathematical model described in Section 3 - (2) can be used to calculate the Z_ (1M) - N curve of a buffer bottle and its simple load system. If you know the law of pulsatile flow, you can calculate the pressure pulsations P_ (1M) and P_ (sM). However, the above model involves only three simplified calculations of typical loads. Here we discuss the calculation of complex real load systems. Using this method can theoretically calculate the pressure pulsations and flow pulsations at any point on various lines. In addition, if you need to be included in the catheter wall and some components of the impact of the shell, it is also possible.
