Deployment Simulation of Inflatable Membrane Tube

According to the model of folded inflatable membrane tube established by Kane method in the multi-body model,the deployment property of V-shape folded inflatable membrane tube was studied by simulation in this paper.The relationship between inflation time and deployment acceleration under various inflation rate and initial angle was obtained in accordance with inner pressure and inflation time.The results showed that the simulation was correct.The deployment acceleration was in proportion to inflation rate generally.It was necessary to control the acceleration fluctuation within a certain deployment angle to improve the deployment dynamics.
