Abstract
The buffering airbag is one of the most important technologies for the landing impact attenuation of dropped equipments. A designed simplified airbag had been used to study cushion characteristics of self-inflating buffering airbag based on experimental method. Every possible combination of factors and factor levels was considered in the experiment. The influence factors of cushion characteristics were researched through the results. The results show that acceleration and pressure inside the airbag are affected by the initial landing velocity, mass of the load and the initial state of vent orifices. Then the simulation model of airbag was established and validated by experimental results. The simulation results agree very well with the experimental results. The established model can be used for further research of cushion characteristics.
