Abstract

The invention provides a system and method for testing the fluid pressure and intensity withstood by a fan blade. The system comprises a box body which defines a cavity, wherein the cavity stores the fan blade; a drive device which is provided with a transmission rod extending to the interior of the cavity to be connected with the fan blade, wherein the fan blade is driven by the transmission rod to rotate; a fluid source which provides fluid to pass through a pressurizing pump to enter the cavity of the box body so as to enable the fan blade in the cavity to rotate in the pressurized fluid. After preset rotation time, the fan blade stops rotating, and the intensity of fluid pressure withstood by the fan blade according to the changes of at least one of the shape of the fan blade, the work performance and the work abnormal noise.

Description

【Technical field】 [0001] The invention relates to the field of fan blade testing, in particular to a testing system and a testing method for fan blades to withstand fluid pressure. 【Background technique】 [0002] The design, development and analysis of early fans were mostly based on the measurement of wind tunnel experiments. Fans can be tested through wind tunnel experiments to test the performance curves of fan static pressure and air volume, and to test wind shear noise in an anechoic room to verify the design. [0003] With the ever-changing scientific and technological progress, the computing power of the computer has also been greatly improved, which has promoted the continuous innovation and development of the methods and techniques of numerical analysis, and the computational efficiency has also been greatly improved. Numerical analysis methods, for example, use CFD (Computational Fluid Dynamics) analysis tools to explore the flow field phenomena of the overall fan ...
