【摘要】 人员闸门是反应堆安全壳上的重要组件,在地震工况下需保障其联锁装置的结构及功能完整性。人员闸门传动机构属于多体能动系统,机构间的运动接触关系属于结构非线性范畴,建模难度大。为此,本文提出了一种人员闸门传动机构的简化建模方法,结合设备的模态试验结果,对系统内的转盘齿轮组等复杂结构基于相似性原理进行等效动态特性简化建模。结果表明,简化后的人员闸门传动机构模型在规避了结构非线性问题的同时,其主要模态频率与试验结果的误差低于8%,与试验结果展现出的设备动态特性基本一致。本文所提基于相似性原理的传动机构抗震模型的简化方法,可为类似能动部件的抗震分析提供参考。更多还原

【Abstract】 The personnel gate is an important component of the reactor containment,and the structural and functional integrity of its interlocking mechanism needs to be ensured under seismic conditions.The personnel gate transmission mechanism is a multi-body dynamic system,and the motion contact relationship between the mechanisms belongs to the structural nonlinearity category,which is difficult to model.To address the problem,this paper proposes a simplified modeling method for the personnel gate transmission mechanism,which combines the modal test results of the equipment and simplifies the modeling of the equivalent dynamic characteristics of the complex structure of the turntable gear set in the system based on the similarity principle.The results show that the simplified model of the personnel gate transmission mechanism avoids the structural nonlinearity problem while the error of its main modal frequencies is less than 8% with the test results,which is basically consistent with the dynamic characteristics of the equipment shown by the test results.The simplified method of the seismic model of the transmission mechanism based on the similarity principle proposed in this paper can provide a reference for the seismic analysis of similar energetic components.更多还原
