Abstract
Aiming at the problem that the stability of airship’s posture is destroyed by turbulent flow when the airship leaves the large factory building, the Computational Fluid Dynamics(CFD) numerical simulation and finite element simulation method are used to simulate the condition that airship transport process in lateral incoming flow. The results shows that the turbulent flow of large factory building causes the variation of surface wind load of airship in the transport process, and the equivalent force and moment acting on airship body center show a certain degree of fluctuations; In lateral incoming flow, compared with the case of restrained by mooring tower, the transfer mode without mooring tower will produce less overall displacement and less extreme value of force on mooring rope. The simulation results provide an effective reference for the safety of airship transport process.
