摘　　要：采取一种新方法,即通过观察分析整机的模态动画来确定单个部件在结构设计上的不足并作出相应改进。将综合各项改进措施改进后的整机性能与改进前的进行对比,结果表明:改进之后机床静态性能平均提升40%～50%;动态性能平均提升20%～30%,说明该改进方法是有效的。A new method was employed to discover the designing defection of the modular structure and make corresponding improvement by observing the modal animation of the complete machine. The comparison of the dynamic performance between the initial machine tool and the improved shows that the static performance of improved machine is enhanced about 40% - 50% and the dynamic performance about 20% -30% which proves that the structure improvement is effective.

关 键 词：模态动画 对比法 动态性能改进
