【摘要】 通过理论研究并结合反应堆冷却剂系统中的非线性因素,提出了采用虚拟激励和模态叠加相结合的非线性地震分析方法进行反应堆冷却剂系统地震分析,该方法能够避免阻尼比选取存在的问题,同时又考虑了非线性因素。更多还原

【Abstract】 Based on theoretic study on nonlinear seismic analytical method,and associated with nonlinear factor existing in reactor coolant system,virtual stimulate combined modal superposition method was proposed to analyze reactor coolant system.This method can avoid different structure damping ratio choose malpractice and take nonlinear factor into account simultaneously.更多还原
