摘　　要：针对核能设备大承载、低频隔振需求及核岛内特殊的工作环境,利用典型斜支承结构的几何非线性,设计了一种具有较大承载能力的金属硬隔振支承结构。通过数值计算得到了该结构在额定载荷下的变形量,验证了结构强度。基于动力学理论建立了动力学模型,通过振级落差分析其隔振效果、优化结构参数,并加工了结构样机,通过实机减振试验验证了结构的隔振效果。研究结果表明,该结构在保证承载能力的前提下,具有良好的隔振效果,可为相关隔振结构的设计提供参考。According to the requirements of large load-bearing and low-frequency vibration isolation of nuclear power equipment and the special working environment in the nuclear island,a metal hard vibration isolation support structure with large load-bearing capacity is designed by using the geometric nonlinearity of typical tilted support structure.The deformation of the structure under rated load is obtained by numerical calculation,and the strength of the structure is verified.Based on the dynamic theory,a dynamic model is established,the vibration isolation effect is analyzed through the vibration level difference,the structural parameters are optimized,and the structural prototype is processed,and the vibration isolation effect of the structure is verified through the vibration reduction test of the real machine.The results show that the structure has good vibration isolation effect on the premise of ensuring the bearing capacity,which can provide a reference for the design of related vibration isolation structures.
