摘要： 对传统管路分段集中参数模型进行修正，通过引进动摩擦液阻，提出了适用于研究层流管路动态特性的分段集中参数键图模型、对比该模型与特征线法(method of characteristics)的仿真结果，表明所提出的管路模型是一种高精度模型． 该模型结构简单、计算参数少，适合于复杂管路系统的建模分析.

Abstract: Based on the im provem ent on the conventional sectional lum ped param eter bond graph and introduction of the kinetic friction factor， a new sectional lum ped param eter m odel using bond graphs for dynam ic response investigation of lam inar line was w orked out．The goodness of identity betw een the sim ulation results curves and that of M O C is com paratively ideal，w hich implies that the new model has adequate accuracy． The new model has less calculated param eters，sim pler structure，and is suitable for m odeling com plex line system s．
Key words: laminar flow    sectional parameter method    kinetic friction factor    bond graphs    method of characteristics(MOC)
