核电站环行起重机轮压时程分析
摘要
Abstract
Time history of cart wheel pressure of ring rail crane for nuclear power station during earthquakes is of paramount importance to the design of horizontal isolation device for the crane. To obtain accurate time history of wheel pressure, a linearized model is established for the crane in the case of vertical vibration to analyze key parameters affecting wheel pressure. In addition, Abaqus finite element models are established for containment and the crane, and the models are analyzed at different lifting heights. The simulation proves that the higher the crane lifts, the greater the amplification factor of wheel pressure is.关键词
