| 摘 要： | 近年来航天结构强度分析方法逐渐从工程算法发展到有限元计算方法。这两种方法在强度分析中各自有其优缺点。针对航天运载器中普遍存在的支架底部强度计算问题,采用工程算法和有限元方法进行了对比计算,分析了两种算法各自的适用范围。

| Abstract: | The intensity analysis method of aero structure develops from engineering calculation method to finite element method in recent years. The two methods have their each advantages and disadvantages. In this paper the intensity calculation of bracket bottom which exist at large in aero launch vehicles is calculated by engineering calculation method and finite element method for comparison. The application area of these two methods is analysis. |
