Finite Element Modeling and Analysis of Gantry-type 5-axis Machining Center Structure

基于试验识别机床各结合面参数,本文建立了机床整机有限元模型,并进行了静态、动态和谐响应分析,在此基础上找 出机床结构的薄弱环节,为机床结构优化设计提供技术支持。

Abstact:In this paper, experiments were performed to identify the parameters of interfaces in the machine tool. And these parameters are applied to the finite element modeling of a viaduct type 5-axis machine-center. The static, modal and harmonic analysis of the machining center are carried out in this paper, then we can find the weakness of this machining center, to improve the machine center design.
