　　Based on machine test data,test mode analysis and sensitivity calculation,a design method is proposed to improve the dynamic performance of the machine tool,in which the natural frequencies of the machine tool and the amplitude of frequency response function are taken as the research objects.Firstly,the stiffness and mass sensitivity with respect to natural frequency are calculated to find weaknesses position of the structures,for the main components and the whole machine tool,respectively.
