摘要
为提高飞机铆接工艺试验的预见性,建立飞机薄壁构件铆接干涉配合的数值模拟模型。该模型应用有限元软件ANSYS LS-DYNA,数值模拟单个铆钉在铆接干涉配合中的动态过程,分析在不同外伸量的工艺参数下与所形成的干涉量的关系以及相对应的铆接疲劳寿命。仿真结果表明:在满足相同的墩头尺寸和外观要求下,外伸量为1.1D^1.2D之间时铆接的干涉量均匀分布且铆接的质量最高,疲劳寿命增益最大。
In order to improve the predictability of aircraft riveting process test, build numerical simulation model of aircraft thin-walled structures riveting interference fit. The model uses finite element software ANSYS LS-DYNA, carry out the numerical simulation of a single rivet interference fit dynamic riveting process. Analyze the relationship between process parameters at different overhang and the amount of interference formed by caulking and the corresponding fatigue life. Simulation results show that when meeting the same size and appearance requirements under heading with extended amount of caulking between 1.1D to 1.2D, the riveting interference value distribution is uniform with the highest quality and maximum fatigue life.
