摘要
从血液动力学中左心室压力曲线和流量曲线出发 ,用多组液压缸产生正弦流量 ,以傅里叶级数叠加的方法 ,模拟出流量曲线。利用Westerhof模型模拟体动脉树从而得到压力曲线 ,利用此方法模拟的生理曲线 ,具有准确、灵活、可调等明显优点 。
With Fourier Series as a tool, we analyzed the flow wave and the pressure wave which were tested at the root of the aorta. A set of hydraulic devices which could produce sine flow were used to simulate the flow wave. Using the Westerhof model as left ventricle afterload we got the pressure wave. This design is relatively accurate and flexible.
