利用有限元法可精确计算CNG2型气瓶各部分应力的特点,提出了以内胆材料屈服强度为基础、以屈服率为判据的计算CNG2型气瓶自紧压力的新方法,开辟了快速准确计算并指导气瓶生产的新途径。
The finite element method can be used to accurately calculate the stress of each part of CNG2 cylinder. Based on the yield strength of the liner material, a new method for calculating the self-tight pressure of CNG2 cylinder based on the yield rate is proposed, which opens up a fast and accurate method New ways to calculate and guide cylinder production.
