摘要
结构测试是检验叶片产品与设计吻合性以及设计准确性的必要手段,准确地验证大型叶片的结构特性成为提高叶片结构设计与制造可靠性的关键环节。本文从理论建模分析、静力加载方式、疲劳加载方式和变形、应变、频率测量方面研究如何提升大叶片的全尺寸测试准确性,通过对比分析获知测试结果准确性高的方法和手段。
Structural testing is a necessary means to test the consistency and accuracy of the design of the blade product.Thus,accurately verifying the structural characteristics of large blades has become a key link in improving the reliability of blade structure design and manufacturing.Research on how to improve the full-scale test accuracy of large blades is studied from theoretical modeling analysis,static loading methods,fatigue loading methods and deformation,strain,and frequency measurement.Methods and means of high accuracy of test results are obtained through comparative analysis.
