作为金属热防护系统的重要组成部分,金属蜂窝夹芯板的性能和结构可靠性关系到使用寿命。本研究采用数字散斑相关技术和时间序列散斑检测技术,对蜂窝夹芯板共面拉伸性能进行试验研究,测得共面拉伸弹性模量,与利用等刚度法计算得到的蜂窝夹芯板的等效弹性模量进行对比,结果吻合较好,验证了数字散斑相关技术的有效性和实用性。 As an important part of the metal thermal protection system, metal honeycomb sandwich panel performance and structural reliability related to the service life. In this study, digital speckle correlation technique and time-series speckle detection technique were used to study the coplanar tensile properties of honeycomb sandwich panel. The tensile modulus of coplanar tensile was measured and compared with the honeycomb clip The equivalent elastic modulus of the core is compared and the result is in good agreement, which verifies the validity and practicability of the digital speckle correlation technique.
