缠绕层表面缺陷对CNG-2复合气瓶爆破压力的影响
Effect of Rectangular Groove Surface Defect to CNG-2 Composite Cylinder’s Burst Pressure
摘要
Abstract
The simplification about surface defects on the CNG-2 composite cylinder to a certain size rectangular groove was made through the actual shape of the surface defect inspection.Burst test and finite element analysis by FEM software ANSYS were made to study the impact of 2 mm deep rectangular groove surface defect to the CNG-2 composite cylinder′s burst pressure.It was concluded that the impact of 2 mm deep rectangular groove surface defect to the stress of cylinder liner was not obvious,while the impact to composite wound layer was significantly.The stress of the bottom of 2 mm deep rectangular groove sur-face defect exceed the guaranteed value of composite tensile strength made the composite cylinder′s burst pressure decrease.关键词
