| 摘 要： | 以国内某钢厂一台离心式鼓风机框架式动力基础为工程实例,对其动力响应与平台厚度和立柱尺寸的灵敏度进行了数值分析计算。结果表明:平台板厚度对基础自振频率、平台振幅影响较小,对平台振动速度影响比较明显;立柱截面尺寸对基础自振频率、平台振幅、平台振动速度影响很显著。

| Abstract: | Base on an actual example,the three-dimensional calculation model of the frame foundation is established,numerical calculation and sensitivity analysis of floor thickness & pillar section size on dynamic behavior of frame foundation is accomplished.The results show that the floor thickness has little influence on the self-frequency and the vibration amplitude of frame foundation,but it has notable influence on the vibration velocity of frame foundation;the pillar section size has a greater influence on the self-frequency,the vibration amplitude and the vibration velocity of frame foundation. |
