The accuracy analysis on control factors of hot bitumen flow

摘要

In order to achieve the description of flow dynamics of hot asphalt in pipeline system and to solve the accuracy problems of process control of asphalt, the paper presents a hot asphalt piping system modeling method based on the bond graph theory. It realizes the project solution of the flow characteristics of hot asphalt in pipeline system which is easy to describe, and provides a strong theoretical support for parameters design of the components matching in asphalt piping system. Finally, the paper proves the effectiveness of hot asphalt pipeline system model method based on the bond graph theory by comparing the steady-state results of physical experiment and system simulation.
