摘要
以高速数控车床CK7516GS为研究对象,对其动态特性进行了多工况的振动测试并采用Matlab软件对数据进行了处理.通过数据分析得到了各个工况的振动主频范围,并把各个工况对应的主频进行了对比,同时对振源进行了分析.测试结果表明:高速数控车床不同工况下振动主频大部分都集中在100Hz附近,其振动主要由切削力、电主轴旋转不平衡以及电磁力不平衡引起的.该分析为高速数控机床的系统动态设计和振动抑制提供了参考依据.
The CK7516GS CNC lathe was used as an object of the study in this paper.The vibration testing of dynamic characteristics was carried out under different working situations,and then the data was processed by using Matlab.According to analysis of the data,vibration frequency range was gained and compared with the corresponding working situation,and then the sources of the vibration were detected and analyzed.The results show that the main frequency under different conditions of CNC lathes concentrates largely in the vicinity of 100 Hz,which is mainly caused by cutting force,the imbalance spindle rotation and the unbalanced electromagnetic force.this paper provides references for the dynamic designing and vibration controlling of the High-speed CNC machine tool.
