The fluid column separation occurring in the pressure control line of the antilock braking system (ABS) of vehicles was analyzed by numerical simulations, and the results were compared with those obtained experimentally. As the experimental setup, the ABS for passenger cars installed on a test stand was used. The pressure fluctuation was measured with a pressure sensor installed on the pressure control line. Four cases of numerical simulation were studied. The calculation method was the characteristic curve method, and the viscosity-elasticity model was used for the braking hose. The first case of simulation was one in which a model with no fluid column separation was used. The other cases used models that differed with respect to the handling of the gas column structure. The simplest model was the one that took no account of the generation mechanism and the structure of the gas column. Other models considered the generation mechanism and the structures of the gas column, which were a single large bubble of air and a group of minute bubbles. In this paper, the limitation of calculation with no model and the validity of the models were described.
