摘要
本文采用截面状态矢量法和模态参数识别方法识别出CM1107单轴纵切自动车床主轴部件的支承参数和模态参数。研究结果表明,在没有FFT分析仪的情况下,利用频响分析仪BT6A测试得到的传递函数也能达到较高的参数识别精度。
The state vector methd of cross-section and modal analysis methd are used to identify the support and modal parameters of the spindle unit of the single spindle longitudinal automatic lathe Mod. CM1107. Results of investigation show that in the absence of FFT analyser, using frequency response analyser Mod.BT6A,the identified transfer function with more high accuracy can be obtained.
