在B777的研制过程中，波音公司除了用分析方法对结构完整性和安全性进行估算外，还通过结构试验对分析结果进行了验证。结构试验着眼于新飞机的各个方面，包括用于新材料性能研究的小试片试验、机身长桥等结构元件试验、机翼上壁板等组件试验、机身部件试验乃至全尺寸静力和疲? In the process of developing the B777, Boeing Co., Ltd., in addition to using analytical methods to estimate the structural integrity and safety, also conducted structural tests to verify the results. Structural tests focus on all aspects of the new aircraft, including small test strip testing for new material performance studies, testing of structural elements such as fuselage long bridges, component testing of wing top panels, body part testing and even full-scale static And tired?
