【摘要】：由于相关钢制内胆环缠绕气瓶设计制造标准中未明确指定内胆壁厚的设计公式,使得市面上同样规格的环缠绕气瓶内胆壁厚和自紧压力等参数存在一定差异,给监管工作带来不便。首先全面总结了环缠绕气瓶钢制内胆的设计方法,然后根据设计结果建立有限元分析模型,对比分析了不同标准体系设计的气瓶内胆壁厚的差异,以及由于壁厚差异而引起的纤维应力比和自紧压力的变化。结果表明,GB 5099相比于其他两种标准体系内胆设计壁厚偏大,相差约4.35%~6.0%;导致相应的环缠绕气瓶纤维应力比相差3.5%~30.8%,自紧压力的合理范围也存在差异。
[Abstract]:Due to the unspecified design formula of the inner tank wall thickness in the design and manufacture standard of the steel inner ring winding gas cylinder, there are some differences in the parameters of the same specification on the market, such as the inner liner wall thickness and the self-tightening pressure, etc. This paper summarizes the design method of inner tank made of annular winding gas cylinder, and then establishes the finite element analysis model according to the design result, and compares and analyzes the difference of the inner wall thickness of gas cylinder designed with different standard system. The results show that the wall thickness of GB5099 is larger than that of the other two standard systems. The difference is about 4.35 and 6.0, which results in the difference of fiber stress ratio of the corresponding annular wound cylinders between 3.5 and 30.8, and the reasonable range of self-tightening pressure is also different.
