| 摘 要： | 根据实验检测的切削信号，分别建立了不同磨削条件下的颤振位移和磨削力的ＥＡＲ模型，同时依据已建立的ＥＡＲ模型，通过Ｌｙａｐｕｎｏｖ指数的分析计算，探讨混沌可能出现的切削条件，进而判断磨削系统是否发生混沌现象．图３，参７

| Abstract: | On the basis of sample cutting signal checked by experiment, chatter displacement EAR model and grinding force EAR model were respectively constructed under the various grinding conditions ,According to EAR model,Lyapunov exponent is analyzed and calculated, the cutting condition in which chaos appears is discussed,consequently whether chaos arises is determined.3figs.,7refs. |
