| 摘 要： | 利用试验台模拟加工中心主轴系统安装状态下的空运转试验,结合DASP分析系统测得主轴系统的动态响应,基于随机子空间识别技术,用MATLAB软件编制相应的识别程序,剔除系统运转中的激励频率成分,选择合适的模型阶次,获得加工中心主轴系统的模态参数,识别结果与脉冲激励识别结果有一定的对应性,为主轴系统的结构改进设计提供依据.

| Abstract: | The spindle system of machine center is set on the spindle tester, During the spindle is rotating at different speeds at idle, Test data of spindle system is measured. The data acquisition and signal analysis system DASP2003 is adopted. Based on stochastic subspace identification method, procedure identify is establishment by MATLAB. After removing those frequencies inspired by spindle, motor and meshing gears, parameters of spindle system is obtained by collecting acceptable orders of modal, that correspond with results of impulse exciting. |
