摘　　要：为推动星箭连接环产品的标准化、型谱化,必须精准分析连接环在卫星发射阶段的应力与变形并评估其承载能力。将星箭连接环上的力学作用分解为线性的发射过载与非线性的包带接触,采用ABAQUS软件建立接触与过载的组合分析模型,时序上的分步分析使得非线性求解能够收敛。分析结果表明:包带约束对连接环的应力、变形影响明显,该型星箭连接环最大可承载质量3 500 kg、质心高度2 m的卫星。Accurate calculation of stress and deformation during launch and bearing capacity evaluation are crucial to standardization and serialization of adapter ring.By deviding the mechanical action on the ring into the linear launch overload and the nonlinear clamp contact,a finite element model with contact analysis was constructed in ABAQUS software,and analyzed by sequential steps to achieve convergence.The results show that clamp constraint has a significant impact on adapter ring stress and deformation,and that the maximum bearing capacity of the ring can sustain a 3500 kg satellite with 2 m high in centroid.
