摘要: 为了较为准确地识别出结合面等效参数,提出利用传递函数和模糊优化识别机械结构结合面参数的新 方法,给出了理论公式和算例分析·该方法克服了传统方法的一些缺点,在传递函数最大随机误差为5%的条件 下,辨识误差不大于5.2%,与传统的最小二乘法相比,显著提高了结合面参数辨识精度·Abstract: To identify the parameters of a mechanical joint precisely, a new method based on transfer function and fuzzy optimization was proposed. The theoretical formulas and numerical analysis were presented. The numerical results demonstrate that the new method overcomes the disadvantages of the least square method and is more accurate. The presented example shows that the identification error is not larger than 5.2% under the condition that the with a maximum random error is 5% in the transfer function.
