【摘要】 用具有快速付里叶变换系统的仪器进行机床模态分析，可以很形象地看出机床的振型和薄弱环节，是评价机床和新产品设计的有力工具。本文以一例实验说明其主要原理、过程和结论。目前，我国已在引进此项技术和仪器。更多还原

【Abstract】 The modes of vibration and weak links are observed from a test on modal analysis of machine tools with fast transfommed Fourier system. It is a powerful tool in evaluation of existing machine tools or a newly designed product. This report presents its main principle, process and conclusion with an example. Now, some instruments and this technique are being led in our country.更多还原
