Abstract
This paper presents an experimental and simulation analysis investigation into the dynamic response of plane cable-membrane structure under impact load. Firstly, the impact tensile tests of the PVDF coated fabric were carried out, and the effect of strain rate on the mechanical properties was characterized. Then the experiment of a plane cable-membrane structure under impact load is carried out. The effects of prestress, impact velocity, and bullet shape on the vibration law of membrane surface are studied. Finally, the mechanical response of the plane cable-membrane structure under impact load is simulated by ABAQUS/Explicit, and the energy dissipation mechanism is characterized. The results show that the displacement of membrane surface increases with the increase of impactor velocity, and decreases with the increase of membrane prestress. The vibration frequency of the membrane surface is the inherent property of structure, which is affected by the prestress of the membrane surface and increases with the increase of prestress. The proportion of elastic strain energy in total energy consumption increases with the increase of prestress. The finite element (FE) models provide a reasonable prediction of the dynamic response of the plane cable-membrane structure under impact load.
