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 。
Based on the improvement on the conventional sectional lumped parameter bond graph and introduction of the kinetic friction factor, a new sectional lumped parameter model using bond graphs for dynamic response investigation of laminar line was worked out. The goodness of identity between the simulation results curves and that of MOC is comparatively ideal, which implies that the new model has adequate accuracy. The new model has less calculated parameters, simpler structure, and is suitable for modeling complex line systems.
