| 摘 要： | 采用ANSYS FLUENT软件仿真计算了某型号液体火箭发动机诱导轮在空化情况下的流场压力分布情况,之后将其流体压力分布引入ANSYS Workbench中,利用单向流固耦合技术进行了该诱导轮的有限元静应力分析,获取了空化及非空化情况下诱导轮的叶片应力分布,分析了空化对诱导轮应力分析结果的影响。 |
| 关 键 词： | 诱导轮 应力分析 空化 流固耦合 |

| Abstract: | ANSYS FLUENT software was used to calculate the flow pressure distribution of a liquid rocket engine inducer under the condition of cavitation.The hydrodynamic pressure distribution was introduced into ANSYS Workbench software to perform finite element static stress analysis of the inducer by the one-way fluid-solid coupled technology.The stress distribution on the blades of a inducer was obtained under the conditions of cavitation and noncavitation.The effects of cavitation on the stress analysis result of the inducer are analyzed. |
| Keywords: | inducer stress analysis cavitation fluid-solid coupled stress analysis |
