摘要:
在M2120A原机床动态测试的基础上,建立包括结合面动力学模型在内的整体机床有限元模型; 对机床主要单个部件进行结构动态优化设计,并利用原机床结合面动力学模型,建立M2120A新机床整机的有限元模型.本文提出以整机第1阶模态的磨头与工件之间相对位移量最小为评价函数,进行整机多方案比较优化设计.与传统的单件优化设计比较,这种优化方案具有考虑更全面、效果更可靠的优点.
Abstract:
The FEM (finite element model) of a whole grinder including dynamic model of combined surface is built based on the results of dynamic test and analysis for old M2120A internal grinder, and dynamic optimal design on structure is carries out for the main parts of the grider. The FEM of new grinder is built using the combined surface model of the old one. The idea for the least of relative vibration displacement between grinder wheel and workpiece at first-step mode to act as an evalution function is put forward in this paper, and optimal design of the multi-project is processed. This optimal method is remarkably comprehensive and reliable.
