远场地震下某型精密生产设备的功能损失评价
Functional Loss Assessment of a Type of Precision Manufacture Equipment Under Far-field Earthquakes
摘要
Abstract
Building resilient supply chains requires effective prevention and control of the risks that natural disasters,such as earthquakes,may bring to key nodes in the supply chain.With the increasing popularization of the application of big data,Internet of Things,artificial intelligence and other technologies,the manufacture equipment of precision electronic components(hereinafter referred to as precision equipment)has become the key link in the supply chain of the microelectronics industry,and is also the most expensive component.The rea-sonable assessment of its functional loss is an important basis for the prevention of the seismic risk of the supply chain of the microelectronics industry.By taking a precision manufacture plant as the research object,and using the events in which its certain precision equipment suffered functional loss in far-field earthquakes from 2014 to 2023 and the seismic ground motion data obtained nearby,the precision-manufacture-oriented functional loss model and assessment method of loss levels are established.The results show that,compared with other ground motion intensity measures,1/3-octave root-mean-square velocity with a center frequency of 0.4 Hz(VRMS(0.4 Hz))has the strongest correlation with the damage rate,and the functional loss curves based on it are fitted with the highest quality.When VRMS(0.4 Hz)of the ground motion around the precision component manufacturing plant is only about 12 mm/s,it is possible to affect the normal function of the precision manufacture equipment at a serious level.关键词
