| 摘 要： | 用MSC Nastran对2种发动机盖支撑杆结构进行屈曲分析.计算结果表明，2种结构支撑杆的屈曲临界载荷均未超过稳定性要求，不同的结构形式具有不同的屈曲临界载荷和屈曲模态，撑杆结构是影响支撑杆稳定性的重要因素.第二种结构方案的屈曲临界载荷大于第一种方案，为设计部门选取更适合的方案提供参考.

| Abstract: | The buckling of two kinds of hood support rods are numerically simulated by MSC Nastran. The calculation results show that the critical buckling loads of two kinds of support rods are not beyond the requirements. The different designs have different critical buckling loads and the structure is the important factor for the buckling performance. The buckling critical load of the second structural schemes is greater than the first scheme, which provides the basis for design department. |
