摘　　要：开展了工艺参数对碳纤维增强复合材料环状结构件的内圆车削力影响研究,搭建了车削力测量系统,测试了不同车削工艺参数条件下不同分量方向的车削力。对车削力测试数据进行了正态分布拟合,避免偶然波动对车削力分析结果的影响;采用传统指数型数学模型和二次完全回归型数学模型,分别对不同车削力分量的经验公式进行了拟合,并对拟合的确定度进行了计算分析。结果表明:除切向力指数型经验公式的确定系数小于95%外,其他经验公式的确定系数均大于98%,其中切向力和径向力的回归型经验公式的确定系数高达99.7%,说明基于两种模型的车削力经验公式的拟合度均较好,且回归型经验公式拟合结果与实际测试结果的符合性略高。The internal turning force of carbon fiber reinforced polymer annular structure is studied,and a turning force measurement system is established.The turning force components of different directions under different turning parameters are tested.The turning force measurementsare fitted with normal distribution which can avoid accidental fluctuations.The traditional exponential mathematical model and the quadratic regression mathematical model are used to fit the emprical fromula of turning force components of different directions.The determination coefficients of the fitted emprical fromula are calculated and analyzed.The results show that excpet the determination coefficient of the emprical formula of depth-cutting resistant force fitted by traditional exponential mathematical model is less than 95%,other determination coefficients of different emprical formulas are more than 98%.Especially,the determination coefficients of the emprical formula of main-cutting force and depth-cuttingresistant force fitted by quadratic regression mathematical model reach 99.7%.The fitting degrees of the turning force emprical formula based on the two models are good,and the fitting data of regression empirical formula is slightly more consistent with the measured data.
