Simulation on the large-scale vehicle flexible fluid-filled structure

The effect of large-scale vehicle flexible fluid-filled structure and contained fluid is a typical problem about fluid-structure interaction. First, the initial state of fluid-filled flexible structure is obtained indirectly through incorporating control volume method and ALE method. Then, the three-dimensional simulation of large-scale flexible structure is completed based on ALE method and the dynamic behavior of this structure in braking is analyzed. Through comparing the experimental data with the simulation results, the feasibility of this simulation method is proved, which provides reference for the design of flexible structure and the improvement of vehicle performance.
