【摘要】：人體血液模擬循環(huán)系統(tǒng)(MCS)的目標(biāo)是重現(xiàn)心血管血流動(dòng)力學(xué)的特性。Westerhof阻力器在MCS中擔(dān)任層流液阻器的角色,用來模擬心血管系統(tǒng)的外周阻力。Westerhof阻力器的理論計(jì)算結(jié)果較實(shí)際的液阻值有較大的誤差,如果將理論公式計(jì)算的液阻值當(dāng)作實(shí)際的液阻值,那么精確度明顯達(dá)不到設(shè)計(jì)目標(biāo)和性能要求。為了減少阻力器液阻值理論計(jì)算結(jié)果與實(shí)際值之間的誤差,本文提供了一種有效的Westerhof阻力器計(jì)算阻值的校正方法,并且開發(fā)了仿真模擬軟件。仿真軟件可以較為準(zhǔn)確地預(yù)測毛細(xì)管數(shù)量、總長度、液阻值,降低和簡化了設(shè)計(jì)阻力器的難度和復(fù)雜度,使得Westerhof阻力器制作更為精準(zhǔn),為各種循環(huán)模擬系統(tǒng)的構(gòu)建提供了支持。
[Abstract]:The aim of the human blood simulation circulatory system (MCSs) is to reproduce the characteristics of cardiovascular hemodynamics. Westerhof resistive devices act as laminar fluid dampers in MCS. The theoretical calculation results of the peripheral resistance .Westerhof resistor used to simulate the cardiovascular system have greater error than the actual liquid resistance value. If the theoretical formula is taken as the actual liquid resistance value, So the accuracy is obviously not up to the design objectives and performance requirements. In order to reduce the error between the theoretical calculation results and the actual values of the resistor, this paper provides an effective method for calibrating the resistance value of the Western of the resistor, and develops a simulation software. The simulation software can accurately predict the number, total length and liquid resistance of capillary, reduce and simplify the difficulty and complexity of designing the resistor, make the Westerhof resistor more accurate, and provide support for the construction of various cycle simulation systems.
