    摘 要:如何使組合變油箱既滿足安全可靠的前提條件,又充分提高鋼材等原材料的利用率,節(jié)約成本,在現(xiàn)如今尤為關(guān)鍵。基于組合變油箱在非勻稱載荷條件的實(shí)際工況下,采用兩種不同模式的力學(xué)疊加態(tài)計(jì)算方法,對組合變油箱加強(qiáng)筋的布局方式和材料用量進(jìn)行了優(yōu)化,在滿足極限工況產(chǎn)品安全的條件下,最大限度地達(dá)成了降低鋼材使用量這一目的。經(jīng)有限元仿真分析及實(shí)物樣機(jī)試制,驗(yàn)證了該研究的可靠性和有效性。

    Abstract: How to make the combined variable oil tank meet the preconditions of safety and reliability and to fully improve the utilization rate of raw materials such as steel is becoming particularly critical. Based on the actual working operation of the combined variable oil tanks under the non-uniform load conditions, the paper adopts two different modes of mechanical superposition calculation methods to optimize the layout of stiffener and material consumption of the combined variable oil tanks. Then, the goal of reducing the steel consumption is achieved to the greatest extent under the extreme working condition of product safety. The reliability and effectiveness of the study is verified by finite element simulation analysis and physical prototype trial production.
    Key words: combined variable oil tank; stiffener; superposition state mechanics; iterative calculation; structural simulation
