摘　　要：以MJC112 5型精密裁板锯为样机 ,对机床的动态特性进行了研究。在研究过程中 ,选取了与产品的表面精度有主要关系的固定工作台、双滚轮式移动工作台 ,并通过锤击法进行实验模态分析 ,得到了模态参数 ,从而评估了机床的动态特性 ,同时为该机床的动态优化设计提供了坚实的理论基础和可靠的数据 ,也为同类木工机床的动态特性研究提供了有效的途径。The dynamic characters of the panel saw, model MJC1125, were investigated. During studying, the fixed working table and double idler wheel push table of the saw, the main influence factors for product's surface quality, were analyzed with experimental modal analysis by striking method. And we got modal parameters and evaluated the dynamic characters. These work will supply theory foundation and data for the optimization design for the panel saw and a reference for dynamic characters study on woodworking machines.
