摘　　要：提出新型组合结构圆锯片基体,为锯切大幅面制品提供了可能的有效途径。针对金刚石圆锯片在锯切加工过程中出现的振动问题,利用有限元软件ANSYS对普通圆锯片和组合结构圆锯片进行了模态分析,得到了各自低阶固有振动频率及主振型图并进行对比。结果表明:组合结构圆锯片和普通圆锯片的低阶振型都明显有节圆和节直径的特点,且都为少节圆或无节圆振型;前12阶扩展模态分布具有一定的规律性,在初始5阶模态状态时频率波动较小,从第6阶模态以后分布波动较大,且波动幅度最大约为30Hz。The new combined saw blade is presented to offer a possible effective way of machining stone products with wide breadth. Pointing to the vibration of the diamond saw blade in machining process, the modes of common diamond saw blade and combined diamond saw blade are analyzed by the finite element software ANSYS to get the intrinsic frequencies and the vibration modes. The result indicates that their low vibration modes both have the characters of cirque and diameter obviously, and they are the vibration modes of little or none cirque. The vibration modes of first 12 have some orderliness： the frequencies slightly fluctuate in the first 5. From the 6th vibration mode, they acutely fluctuate and the most fluctuate swing is about 30 Hz.
