摘要

对单层球面网壳结构进行了网壳结构冲击试验，并采用ANSYS/LS-DYNA对网壳结构受冲击荷载作用进行了参数分析。根据网壳受冲击后的变形及破坏形态，定义了4种冲击响应模式。针对不同冲击响应模式间的转换规律，提出利用临界冲击动能作为网壳结构的抗冲击性能的评价指标，并分析了不同钢材强度对结构抗冲击性能的影响。结果表明，单层网壳结构的冲击响应模式随冲击物动能呈规律性变化，利用临界冲击动能可以方便的对网壳结构抗冲击性能进行评价，使用高强度材料可有效提高单层网壳结构的抗冲击性能。

Abstract

A series of impact experiments to single layer reticulated shell were conducted to verify the accuracy of FEM model established by ANSYS/LS-DYNA. Using the verified FEM model, a large number of parametric analyses were conducted to simulate the single layer reticulated shell subjected to impact load. According to the final deformation and failure form, 4 kinds of impact response modes were defined. Based on the changing regular between different impact response modes, the critical impact kinetic energy was proposed to evaluate the impact resistance for single layer reticulated shell. And the effects of various materials on the impact resistance of single layer reticulated shell are analyzed. The results show that the impact response modes change regularly with the kinetic energy carried by impact load. The impact resistance of reticulated shell can be analyzed conveniently by critical impact kinetic energy. The high-strength material can significantly improve the impact resistance of single layer reticulated shell.
