针对冲击试验中试件连续冲击会使曲线产生较大偏差的现象,对冲击响应台的波形发生器的应力释放行为进行了有限元分析,并对波形发生器进行了冲击试验,改变波形发生器的静置时间,对比不同静置时间下的冲击波形,通过热处理的方式,加快波形发生器的形变回复,进而提高冲击试验的试验精度.研究可为今后对冲击响应谱试验波形发生器的研究和应用的参考提供了理论基础.
Residual Stress Release Characteristics of Waveform Generator in Shock Response Spectrum Test
In response to the phenomenon of significant deviation caused by continuous impact of specimens in impact tests,finite element analysis was conducted on the stress release behavior of the waveform generator of the impact response table.The waveform generator was subjected to impact tests by changing its static time and comparing the impact waveforms under different static times.Through heat treatment,the deformation recovery of the waveform generator was accelerated,thereby improving the experimental accuracy of the impact test.The research provides a theoretical basis for the future research and application of waveform generators in shock response spectrum tests.
