Strength Analysis and Optimization Design of A Platform Used for Transporting and Releasing Large Stratospheric Airship
View through CrossRef
It is important to transport and release a large airship safely because of the big size. In order to complete the transfer of large stratospheric airship, a truss transfer platform is built. Based on MATLAB and FEMAP, a semi-parametric method is used to establish the model of the platform which is consisted of rectangular steel tube in this paper. With a finite element software ABAQUS, a study of mechanical property of the platform is carried out. The simulation result shows that the force of the platform is mainly caused by the weight of trusses. The force of airship and other attached devices has little effect on the structure. Then, optimal parameters of extended platform are obtained according to the mechanical properties and optimization design. At last, the simulation results are verified by the experiment.
