Problems solved by technology

A lot of picture data, temperature data, frequency response data and fatigue test data are obtained through blade fatigue tests. When the data volume is large, it is obviously inefficient to use different software to process it manually, and it is also not reliable in terms of data processing. be effectively guaranteed
After the test, the test personnel need to issue a blade fatigue test report. The key charts in the test need to be given in the report, and the key data need to be converted into text and charts in the report. These key data charts are scattered in various instruments and equipment and processed manually wasted a lot of time and energy

Embodiment Construction

[0082] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0083] The embodiment of the present invention provides a post-processing method based on Matlab blade fatigue test data, the blade fatigue data includes image data, temperature data, frequency response data and fatigue test data,

[0084] The method comprises the steps of:

[0085] a. Image data processing,

[0086] The picture data includes photos of the overall state of the blade taken before the test, photos of the overall state of the blade taken after the test, and pictures of partial cracks in the blade; photos of the overall state of the blade were taken before and after the test, and if cracks occurred in the blade, local pictures of the cracks were taken. Use a high-definition camera to obtain picture data, and the picture data is saved in the computer.

[0087] Use Matlab to read in the photos...

Abstract

The invention discloses a blade fatigue limit evaluation method based on Matlab. The blade fatigue test data includes picture data, temperature data, frequency response data and fatigue test data. The blade fatigue test data post-processing method of the present invention is established on the Matlab software platform The above set of test data post-processing method can quickly, comprehensively, systematically and batch analyze the blade fatigue test data, and can quickly obtain the blade vibration characteristics, fatigue limit and S-N curve, which can effectively reduce the processing of blade fatigue test data time, reduce human factors in the processing process, and reduce the number of participants in leaf data processing, which greatly improves efficiency.

Description

technical field [0001] The invention relates to the technical field of blade fatigue test data processing, in particular to a Matlab-based blade fatigue limit evaluation method. Background technique [0002] The blade fatigue test under laboratory conditions is the key to obtain the working life of the blade, and it is more and more concerned by the design and production units of the aviation industry. A lot of picture data, temperature data, frequency response data and fatigue test data are obtained through blade fatigue tests. When the data volume is large, it is obviously inefficient to use different software to process it manually, and it is also not reliable in terms of data processing. be effectively guaranteed. After the test, the test personnel need to issue a blade fatigue test report. The key charts in the test need to be given in the report, and the key data need to be converted into text and charts in the report. These key data charts are scattered in various in...
