摘要
螺栓连接结构的特征参数,对机匣气密性具有重要影响。针对具有纵向安装边的机匣,建立初始模型并对其进行强度分析,研究了不同特征参数对机匣极限内压的影响规律,并得到机匣螺栓连接结构密封公式。将仿真结果与结构特征参数进行拟合,获得多参数变量的临界气压拟合函数,使用多目标优化设计方法,求得结构的最优设计参数变量。所提方法和相关结论可为机匣连接结构参数设计提供技术支持。
The multiple sets of parameters have a significant influence for the casings’ airproofperformance. This article uses multiple sets of parameters to get the law of internal pressure limit ofdifferent parameters aiming to the casing with vertical connecting edge, also get the formula of airproof.Based on these the finite element strength analysis for initial test model, it fits parameters and internalpressure limit, gets the multivariable fitting function. Then, using multi-objective optimization method toget optimal design parameters combination and the solution. Offering a technical support for designing ofbolted joints connection structure with specific demands.
