    摘要:

    描述了蜂窝夹层板内埋件的承载力检测条件和结果,分析了埋件材质及埋件周围填胶量对其承载力的影响。结果表明:相同技术状态下,铝合金与镁合金埋件的承载能力基本相当,而镁锂合金埋件的最大弹性变形载荷与铝合金和镁合金埋件基本相当,但其首次失效和最大破坏载荷相对较低;对于同种材质的埋件,适当增加填胶量,更有利于提高埋件的承载力。研究结果可作为产品设计优化的基础依据。

    Abstract:

    In this work, the pulling test condition and test results of post-insert through-hole connector in the honeycomb panel were discussed.The influence of the inserts raw materials and the adhesive amount around the insert on the pulling strength and bonding quality were analyzed.The results show that aluminum alloy inserts and magnesium alloy inserts almost have the same pulling strength under the same condition.Compare to the aluminum and magnesium,the magnesium lithium alloy inserts have less initial failing strength and ultimate breaking strength but the maximum yielding strength is similar to the other two samples.In terms of one specific inserts,increasing the adhesive amount will be benefit to the pulling strength.The conclusions of this work can be used as references for future product test design and processing configuration setup.
