| مستخلص: | Horizontal shock testing table can be used to evaluate shock resistance ability of warship equipments. Based on this theory, the level of flexible plate oriented shock testing platform is raised. Using the finite element method, the output waveform of the testing platform and the stress distribution of the flexible plate are analyzed in this paper. It can be concluded that flexible plate can be used to store elastic potential energy during the impact and have a certain impact on test waveforms. Theoretical maximum displacement of the platform body is 94mm, the calculated value is 89.5mm, decrease by 4. 8%; theoretical maximum speed of the platform body is 4m/s, the calculated value is 3.93m/s, reducing to1.75%; theoretical, the value of positive wave peak acceleration of platform body is 571m/s2, the calculated value is 532 m/s2, decrease by 6.8%; theoretical platform body negative wave peak acceleration values is 175m/s2, the calculated value of 183 m/s2, an increase of 4.6%. The research shows that flexible plate as a guide device can meet the impact test table for error waveform requirements.. |
