摘　　要：为降低双腔铝合金燃油箱分腔隔板开裂失效风险,文章介绍了一种通过改进分腔隔板结构提高铝合金双腔油箱质量的方法。首先结合同类结构计算机辅助工程(CAE)分析及试验报告,对分腔隔板结构进行了改进,再通过CATIA软件进行建模对燃油箱总成进行装配评估,同时分析了新结构分腔隔板工艺成型情况,最后进行样件试制并进行台架振动试验验证,结果显示这种方法能过够有效克服双腔油箱分腔隔板开裂脱落问题,同时在设计优化过程大大降低了时间成本、人工成本及原料成本。In order to reduce the crack failure risk of the split diaphragm of the dual-cavity aluminum alloy fuel tank,this paper introduces a method to improve the quality of the dual-cavity aluminum alloy fuel tank by improving the structure of the split diaphragm.First of all,combined with the computer aided engineering(CAE)analysis and test report of the same structure,the structure of the split diaphragm is improved.The article then evaluates the assembly of the fuel tank assembly by modeling with CATIA software,and analyzes the process forming of the new structure split diaphragm.Finally,the prototype is trial-produced and verified by the bench vibration test.The research results show that this method can effectively overcome the problem of split diaphragm cracking and falling off of double-chamber oil tank,and greatly reduce the time cost,labor cost and raw material cost in the process of design optimization.
