摘　　要：E-51环氧胶黏剂是航天产品中最常用的一种胶黏剂,主要用于粘固元器件和紧固件防松作用,以此加强产品在力学冲击环境中的适应能力。为了提高E-51胶黏剂的韧性,本研究工作通过添加SiO_(2)纳米颗粒到环氧体系中,然后通过物性参数检测,利用ANSYS仿真软件模拟E-51粘固直插钽电容在高低温环境中的应力分布,分析讨论了SiO_(2)纳米颗粒和不同点胶高度对粘固钽电容应力分布的影响,最终确认环氧粘固钽电容较为合适的点胶高度范围以及SiO_(2)纳米颗粒对应力改善的作用。E-51 epoxy adhesive is one of the most commonly used adhesives in aerospace products.It is mainly used to electronic components and fasteners in order to strengthen the adaptability of products in the mechanical impact environment.To improve the toughness of E-51 adhesive,in this study the SiO_(2) nanoparticles were added into the system of E-51 adhesive,of which new physical parameters were tested and provided for the simulation of stress by ANSYS.The influence of adhesive heights on the stress distribution of tantalum capacitor adhesive system and the influence of SiO_(2) nanoparticles was also discussed and confirmed.
