Example Embodiment

[0099]In this embodiment, an aircraft anti-skid brake control device is taken as an example to determine a correction method for a vibration calculation model of the anti-skid brake control device.

[0100] In this embodiment, the hammer excitation test method and the electric vibration table test method are used to gradually improve the correction accuracy of the finite element calculation model of the anti-skid brake control device, and the calculation mode is corrected by using the test modal data to obtain a high-precision vibration calculation model. . Among them, the hammer vibration test is divided into two-corner suspension and four-corner suspension modal test methods.

[0101] There are two circuit boards of a control board and a recording board in the anti-skid brake control device of the present embodiment.

[0102] During the implementation of the present invention, the test instruments, meters and software used are shown in Table 1.

Abstract

The invention discloses a method of testing anti-skid brake control device vibration response. A force hammer method and an electric vibration table testing method are adopted respectively for actual measurement. When the electric vibration table testing is adopted, testing is carried out in a used maximum and minimum vibration value range, a two-angle method, a four-angle method and the electric vibration table testing method are adopted sequentially for gradually correcting a vibration calculation model for the anti-skid brake control device, the actual using condition of the anti-skid brake control device is met, the precision of a finite element vibration calculation model is improved, and the error of the calculation model after the vibration calculation model is corrected is smaller than 3%.

Description

technical field [0001] The invention relates to the field of vibration fault diagnosis of civil aircraft electronic products, in particular to a method for collecting vibration response data of an anti-skid brake control device, and the test data is used to correct the vibration calculation model of the anti-skid brake control device. Background technique [0002] Test the vibration mode and response data of electronic products under given vibration excitation conditions. The purpose is to correct the calculation model of electronic products, and use calculation methods to determine the weak links of electronic products that are sensitive to vibration and complete design improvements. The ability of electronic products to withstand vibration. [0003] The key to correcting the vibration calculation model is to obtain accurate modal measured data. Vibration modal analysis is divided into experimental modal analysis and computational modal analysis. The former is the data obta...
