| 中文摘要: |
| 利用MSC/NASTRAN和PATRAN软件建立了某微型发动机在随机振动试验时夹具的有限元计算模型,进行了强迫随机振动响应分析,为缩短夹具的设计周期,提高设计水平,提供了一种新的途径;对于基础加速度激励,采用了大质量法. |
| 英文摘要: |
| Based on MSC/NASTRAN and PANTRAN, this article establishes a model of FEM in the fixture figuring in random vibration tests and analyzes the forced random vibration response. It provides a mew method to improve the fixture designing. A large mass method is applied to excite the based acceleration. |
