摘要： 对某机床厂CKS6116卧式数控机床导轨结合面的静、动刚度与阻尼等参数特性进行了研究.首先利用静、动态特性实验得出机床的各项动态参数,然后用ANSYS有限元分析软件模拟和显示机床在考虑导轨结合面参数条件下的各阶模态下的振型和固有频率.最后对整个机床进行激振试验,验证了仿真参数的准确性.说明直线滚动导轨结合面的静、动刚度与阻尼对机床的动态特性具有很大的影响.

Abstract: Such characteristic parameters as static/dynamic stiffness and damping force were studied for the linear rolling guide joint of NC machine tools on a CKS6116 horizontal NC lathe. A static/dynamic characteristic test was done to obtain all dynamic parameters of the lathe, then the software ANSYS for FEA was used to simulate and display various vibration modes and natural frequencies with the guide joint parameters taken into account. In addition, a vibration excitation test was done for the whole lathe to verify the exactness of the parameters obtained from simulation. As a result, it is proved that the static/dynamic stiffness and damping force of the linear rolling guide joint affect greatly the dynamic behavior of NC machine tools.
