压力容器作为承载一定压力或者易燃易爆气体的装置,介于其功能的特殊性,我们对于它的安全性能也具有较高的要求。对于压力容器使用均匀性材料,常常以薄膜应力来计算其整个容器应力水平,复合材料压力容器介于材料的不均匀性,在生产实践中,通常运用牺牲材料以保障安全性的办法。因此,我们十分有必要探讨研究复合材料热力耦合应力问题以及容器的设计方法。本文主要是研究当下主流的三种复合材料压力容器,对其热力的耦合应力进行探讨。
Pressure vessel as a device carrying a certain pressure or flammable gas, in the particularity of its function, we also have high safety requirements for it. For the pressure vessel to use uniform materials, the stress of the whole vessel is usually calculated by the stress of the membrane. The pressure vessel of the composite material is inhomogeneity of the material. In the production practice, the sacrificial material is usually used to ensure the safety. Therefore, it is very necessary for us to study the thermal stress of composite materials and the container design method. This paper mainly studies the current mainstream of three kinds of composite pressure vessels, to discuss the thermal coupling stress.
