3) higher order frequency coupling feature
高次频率耦合特征
1.
For extracting higher order frequency coupling feature radiated by actual nonlinear vibration system via odd-order cumulants(OOC),quartic frequency coupling and quadratic-to-cubic frequency coupling were firstly defined,OOC features analyzed,the relation between OOC calculation method and its computational load was studied.
为了用奇数阶累积量提取非线性振动系统的高次频率耦合特征,定义了四次频率耦合、二三对频率耦合等高次耦合新概念,分析了奇数阶累积量特征,研究了奇数阶累积量计算方法与计算量间的关系,提出了奇数阶累积量计算优化算法,该算法将奇数阶累积量的直接估计变为递推估计,将奇数阶累积量的多维运算转化为一维运算,大幅度减小了计算量,在工程上具有可实现性。
