电气设备振动台试验输入的合理确定
|
摘要
电气设备抗震性能检测最主要的方法是进行振动台试验,而合理确定试验输入是关键。以正弦拍波、人工合成地震波、实际强震记录为例,详细讨论了如何合理确定试验输入,指出了《电力设施抗震设计规范》相关条款存在的问题,为电气设备抗震性能检测标准的制订和相关规范的修改提供合理建议。基于强震记录,利用混合模拟方法,同时拟合3个不同阻尼比(2%、5%、10%)的目标反应谱,给出了适用于电气设备抗震性能检测的输入时程。
It is the key problem to reasonably determine the test input of the shake-table test,which is the most important approach for the detection of anti-seismic performance of electrical equipments.Taking sine-beat,synthetical artifical seismic wave and practical strong earthquake records for examples,how to reasonably determine the test input was dissected in detail.The existing problems in related clauses of the Code for Design of Seismic of Electrical Installations(GB50260-96) were pointed out and reasonable suggestions for the drafting of the standard of detecting anti-sesmic performances of electrical equipments and the revision of related codes were put forward.Based on recorded data of strong earthquakes and using hybrid simulation,three target response spectra with different damping ratios,namely 2%,5% and 10%,were simultaneously fitted and the input time history suitable to the detection of anti-seismic performances of electrical equipments was given.
