Abstract

Abstract

ABAQUS finite element software was used to analyze the bending performance of web core sandwich plate in low temperature environment，and it was compared the deflection value to the theoretical deflection value under temperature-load，finally it was also，compared the influence of the thin web temperature transfer function and plate thickness change on the web core sandwich plate deflection． The results showed that in low temperature environment， the total deflection of elastic stage of the web core sandwich plate increased linearly and the influence of the temperature transfer function increased gradually on the plate deflection as the temperature lowered． The deflection value of considering temperature transfer is smaller than without considering temperature transfer，theoretical deflection value was between the two，the ratio of the value and the total deflection increased with reducing temperature，and tended to be stable gradually; increasing the thickness of the plate，the total deflection was decreasing gradually with reducing temperature，increasing the thickness of the plate could effectively diminish the deflection，but the proportion of the deflection caused by the temperature effect accounted for the total deflection was increased．
