摘要

目的对复杂结构动力可靠度的理论和方法进行简要的总结和评述。复杂结构通常由多个部件组装而成,并承受空气动力学、结构、热和其他物理场的时变载荷;其可靠性分析对保证航空、机械等大型设备的安全运行具有重要意义。设计/方法论/方法在本文中,复杂结构的单目标动力可靠性分析的计算可分为蒙特卡洛法、交叉率法、包络函数法和极值法。总结了用于复杂结构多目标动力可靠性分析的串并展开法、多极值代理模型和分解协调代理模型。以数值复变复合函数和涡轮叶盘为例,说明了单目标和多目标动力可靠性分析方法的性能。展望了复杂结构动力可靠性分析的未来发展方向。本文为进一步的理论研究和工程应用提供了有益的参考。

Structural dynamic reliability analysis: review and prospects
PurposeThe purpose of this paper is to briefly summarize and review the theories and methods of complex structures’ dynamic reliability. Complex structures are usually assembled from multiple components and subjected to time-varying loads of aerodynamic, structural, thermal and other physical fields; its reliability analysis is of great significance to ensure the safe operation of large-scale equipment such as aviation and machinery.Design/methodology/approachIn this paper for the single-objective dynamic reliability analysis of complex structures, the calculation can be categorized into Monte Carlo (MC), outcrossing rate, envelope functions and extreme value methods. The series-parallel and expansion methods, multi-extremum surrogate models and decomposed-coordinated surrogate models are summarized for the multiobjective dynamic reliability analysis of complex structures.FindingsThe numerical complex compound function and turbine blisk are used as examples to illustrate the performance of single-objective and multiobjective dynamic reliability analysis methods. Then the future development direction of dynamic reliability analysis of complex structures is prospected.Originality/valueThe paper provides a useful reference for further theoretical research and engineering application.
