摘　　要：现代机床对其动态特性的要求越来越高,文中采用模态试验研究某龙门加工中心的动态性能。基于机床相对激振试验的理论,对某龙门加工中心进行了相对激振试验,通过试验模态分析得到了整机的模态参数,分析了该龙门加工中心的薄弱环节,及其各种影响因素。The dynamic performance of modern machine tool is more and more highly emphasized. The dynamic performance of some gantry machining center through modal test was researched. Based on the theory of relative vibration test, the relative vibration test on some gantry machining center was made, and the modal parameters of this machine tool through experimental modal analysis was gotten. The weak link of this gantry machining center was analyzed. The results show that the stiffness of Z direction feed system of this machine tool is insufficient, and the stiffness of X, Y direction of ram is insufficient also.
