摘　　要：民用飞机机体结构静强度验证是保证飞机结构安全的基础,是民用飞机获取型号合格证投入市场运营的基本条件。以机体结构静强度验证流程为线索,从分析和试验两方面阐述了当前机体结构静强度验证的思路和方法以及未来的发展趋势。对于金属机体结构,结合少量必要试验,采用经试验验证的分析进行全面静强度验证是当前金属机体结构静强度适航验证较好的工程解决方案,而复合材料机体结构采用积木式验证模式是目前最优化的验证方案。采用传统的内力模型加工程分析方法依然是机体结构静强验证的主要手段,但工作流程,主要是强度校核工作部分,将向自动化方向发展,以满足实际工程分析对效率和质量的要求。同时,全机精细有限元模型分析是机体结构静强度验证重要的辅助手段,代表了飞机结构强度分析未来的发展方向。Static strength verification of civil aircraft body structure is the basis of ensuring the safety of aircraft structure,and the basic condition for civil aircraft to obtain the type certificate and put into market operation.Starting from the process of structural static strength verification,this paper describes the current ideas,methods and future trend of structural static strength verification from aspects of analysis and test.For metal structural static strength,it is a better engineering approach for the static strength airworthiness verification to use the comprehensive static strength verification by the analysis of the test verification combined with some necessary tests,while the"building-block"method for composite structure is currently the optimal verification scheme.The traditional method of internal force model and engineering analysis is still the main solution for structural static strength verification,but the working process,mainly the part of the strength verification,will develop towards automation to meet the requirements of efficiency and quality in actual engineering analysis.Meanwhile,the whole aircraft fine finite element model analysis is an important auxiliary method to verify the structural static strength,which represents the future development direction in aircraft structural strength analysis.
