| 摘 要： | 研究了卫星包带连接的有限元力学建模。基于对包带预紧力、卡块与连接环间的接触力，以及两连接环间的接触力的分析，将接触力等效为有限单元节点力。对所建模型中的非线性项，用Newton-Raphson法求得给定包带顸紧力的平衡位置，再以该平衡位置处的切线刚度对模型作线性化，分析了模态和固有频率等动力学特性。某卫星的算例验证了模...

| Abstract: | The modeling of the marman clamp joint of satellite in this paper.Based on the analysis of the band,the contact forces between the two adaptor rings and between the V-segments and adaptor rings,the contact forces were equivalent to element node forces.The linearization technique was applied for modal and natural frequency analysis as the clamp joint model was nonlinear,and Newton-Raphson method was applied to determine the equilibrium position.The linearized equation was obtained by expanding the nonlinear ... |
