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．
