摘要:
设计完整的铣削加工模态分析实验和动力学实验,完成铣削力和振动信号的采集和分析,并以刀具振动系统为例提出模态参数辨识计算方法.对比动力学实验测量和计算机仿真信号的时域幅值、功率谱特性可知:基于实验模态分析实现系统模态参数辨识技术路线可行,预测精度较高,可较好地应用于铣削力-振动等信号及其时域和频域特性的动态仿真.
Abstract:
A series of experiments, including modal analysis experiments and milling dynamic experiments are designed and performed to collect and analyse milling force and vibration signals. Meanwhile, aking cutter vibration system as example, modal parameters identification methods are put forward. Then, time domain amplitude and power spectrum of dynamic experimental measurement and computer simulation signals are contrasted. The results show that the modal parameters identification technology based on experimental modal analysis are feasible. It has high prediction accuracy and can be better applied to simulate cutting force and vibration signals and their characters in time and frequency domains.
