动力机器基础的数值计算分析与设计

Numerical Analysis and Design of the Foundation of Dynamic Machine

在动力机器基础的设计过程中,除需满足静力条件,还需进行动力响应分析。论文以质-弹-阻理论为基础,以GB 50040—1996《动力机器基础设计规范》为依据,采用Hypermesh建模软件以及ABAQUS有限元分析软件,对某实验楼主机动力设备基础在无桩和有桩的情况下进行有限元动力分析,判断其动力学特征,研究不同因素下的基础动刚度变化规律,为设备基础的非线性计算提供可靠的分析结果。

In the process of designing the foundation of dynamic machine,the static condition and dynamic response analysis should be satisfied.Based on the mass-elastic-resistance theory and the GB 50040-1996 Foundation Design Specification for Dynamic Machinery,this paper adopts the Hypermesh modeling software and ABAQUS finite element analysis software to carry out the finite element dynamic analysis on the main dynamic equipment foundation of an experimental building without or with piles,judges its dynamic characteristics,analyzes the law of dynamic stiffness change under different factors,so as to provide reliable analysis results for nonlinear calculation of equipment base.
