Abstract： A type of bulk cement tanker was focused， several research programs for improving the quality were proposed. The fluidization models of the fluidized bed were created in computational fluid dynamics software FLUENT， then the improved fluidization process was simulated， and the analysis for the fluidizing quality was given. The simulation results showed that the optimized effects which adopted 40°side splitter board, with curve fluidization board substitute rectangle board were able to improve the fluidization quality of the cement in tanker. The improvement of the structure in the original bulk materials vehicles could improve their serviceability and work efficiency.
