摘要
机械结构结合面参数对机械结构系统动力学建模与结构振动控制有着重要的影响。准确合理地识别出结合面等效参数是实现结构系统动态分析与控制的一个关键问题。本论文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。通过与传统的最小二乘法比较表明,该方法克服了传统方法的一些缺点,提高了结合面参数辨识精度。
The joint parameters of the mechanicalstructure have quite important influence on the systemdynamic modeling and control of the structure. Toidentify the joint parameters reasonably and precisely isa key problem in the realization of the system dynamicanalysis and control of the structure. A new method usingtransfer function and fuzzy optimization to identify thejoint parameters of the mechanical structure is presentedand the theoretical formulas and numerical analysis areshown in the paper. The numerical results demonstratethat the new method can overcome the disadvantages ofthe least squared method and can get accuracy results.
