塔机回转平台有限元优化分析

Finite element optimum analysis of slewing platform for tower crane

回转平台的优劣对塔机有着至关重要的影响 ,本文运用有限元板壳理论 ,建立了回转平台有限元模型 ,得出了回转平台的应力分布 ,准确描述了回转平台的受力状态 ,并对该模型进行了优化分析 ,达到了节约用材的目的。

Slewing platform much influences the function of tower crane.This paper uses plate and shell theory of finite element to set up a finite element model of tower crane.It obtains stress distribution of slewing platform and describes its stress state.The model is analyzed optimatically and the material used for the slewing platform is saved.
