In order to improve the accuracy of the airbag-based flexible robot in simulating the human body, and make its surface fit the human body surface better. For the balloon filled airbag in flexible robot, the process of airbag parameters under different gas flow is simulated and analyzed. First, for the traditional airbag inflatable simulation method ignoring the different gas volume flow on the impact of airbag deformation. The air bag inflation control model based on gas volume flow is constructed, the pressure of the airbag inflated is optimized by calculation of gas mass flow simulation inflation and leakage. Finally, the grid unit is used to divide the internal volume of the airbag, and its discrete optimization is carried out to simulate the expansion of the airbag. The simulation results show that the simulation method proposed in this paper can complete the process of spherical airbag. The maximum safety pressure of the airbag and the corresponding temperature are obtained from the simulation results, which can provide the theoretical basis for the surface fitting of the flexible garment fitting robot based on airbag.
