高速五轴联动加工中心主轴箱模态测试分析研究
Research on Modal Testing and Analysis of Spindle Box in High Speed Five Axis Interlocking Machining Center
摘要
Abstract
Modal testing experiments are essential methods and means in the development,finalization,use,and maintenance processes of aviation,aerospace,automotive,shipbuilding,industrial equipment,bridges,buildings,and other industries.Based on the theory of modal testing,an experimental environment is established to conduct modal testing experiments on the front of the high-speed five axis linkage machining center spindle box using a laser vibrometer.Through experimental measurement and data acquisition,the frequency response function curve is calculated using basic analysis software.The first to fourth order modal frequencies of the machining center spindle box front are obtained by excitation,which are 146.25,234.375,332.5,and 373.75 Hz,respectively.The first to third order modal frequencies of the spindle box side are 141.25,216.875,and 266.25 Hz,respectively.The corresponding vibration modes at each order modal frequency are measured.The results show that the modal testing experiment and analysis method used,as well as the testing instruments used,can identify and determine the dynamic characteristics of the mechanical structure such as the natural frequency and vibration mode of the main axle box of the high-speed five axis linkage machining center.It can provide experimental data support for the structural design and optimization of the high-speed five axis linkage machining center.关键词
