Q235钢桶底板涨筋抗振结构优化

Antivibration Optimization by Adding Ring-form Folding on the Floor of Q235 Steel Drum

钢桶是液体危险化学品重要的包装容器,钢桶底板强度对其运输中的安全性起决定性的作用。在不增加厚度的情况下,在传统钢桶底板上设计涨筋以提高其抗振动疲劳寿命,同时采用有限元方法对200LSPCC(cold rolled steel)钢桶进行应力分析和结构优化,以获得桶底板的最佳方案。优化后最大等效应力降低了140%。结合振动试验,钢桶优化后的抗振性能提高了7.42倍,优化效果明显。

Steel drum is an important packaging container for the liquid hazardous chemicals.The strength of the steel drum floor has a decisive effect on its safety during transportation.To improve the antivibration fatigue life of the steel drum,the ring-form folding was added on the floor rather than expanding thickness.Meanwhile,the finite element method was used to perform the stress analysis and structural optimization of the floor of200LSPCC steel drum,to obtain the optimum sheme for steel drum floor design.The maximum equivalent stress of the floor of200LSPCC steel drum reduced by140%after optimization.Combined with the vibration test,the antivibration ability of steel drums after optimization increased by7.42times and exhibited an evident effect.
