The invention belongs to the technical field of wind tunnel tests, and particularly relates to a transonic wind tunnel test system for a grid fan, which ensures that displacement signals captured by a vibration sensing assembly can be completely aligned with pressure data acquired by a dynamic pressure acquisition unit in time by introducing a high-precision data synchronous recording device. Meanwhile, the system is also integrated with an environmental parameter monitor which can track and compensate the change of physical quantities such as temperature, humidity and air pressure in real time, so that the accuracy of experimental data is remarkably improved. Finally, by adding an analysis platform and a result visualization interface, deep analysis of the blade vibration mode is realized, visual and detailed data support is provided for researchers, and understanding of dynamic behaviors of the blade under the transonic speed condition is greatly improved.

    本发明属于风洞试验技术领域,具体涉及一种跨音速叶珊机风洞试验测试系统,通过引入高精度的数据同步记录装置,确保振动感应组件捕捉到的位移信号与动态压力采集单元获得的压力数据能够在时间上完全对齐。同时,该系统还集成了环境参数监测仪,能够实时跟踪并补偿温度、湿度和气压等物理量的变化,从而显著提高了实验数据的准确性。最终,分析平台和结果可视化界面的加入,实现了对叶片振动模式的深入解析,为研究人员提供了直观且详尽的数据支持,极大提升了对叶片跨音速条件下动态行为的理解。
