| 摘 要： | 以阿尔法磁谱仪(AMS-02)热控制系统中支架为对象,运用有限元方法对其关键受力部件进行了结构分析和优化设计.分析了中支架板单元的最大Mises应力和梁单元最大复合应力并进行了强度校验.计算了中支架支撑梁的屈曲临界应力,与极限工况下梁的最小主应力进行了对比.结果表明,目前设计的中支架不存在强度破坏和失稳问题,并有很高的安全裕度.在进一步的优化设计中,以减轻质量为目标函数,发现目前中支架在安全裕度范围内仍可以减轻质量16.6%.

| Abstract: | Based on the study of the mid bracket of the Alpha Magnetic Spectrometer(AMS-02) thermal control system,the methods of structure analysis and optimization for the key parts that bear the main loads of a spacecraft were presented by Finite Element Method.By applying software MSC.Nastran,the maximum Von Mises stress of the plate elements and the maximum combined stress of the bar elements in the mid bracket were analyzed,and the strength verifications were performed.The Euler loads and the critical buckling s... |
