Study of Nonlinear Characteristic on Metal Mesh Vibration Damper
摘要
研究了某金属丝网减振器非线性特性
建立兼有干摩擦和线性阻尼特性的混合型阻尼模型
根据数学模型与实测数据的误差最小对所建模型的参数进行了识别
最后得到了模型中的待识别参数.结果表明:所建的数学模型比较合理
能够合理反映兼有不同性质阻尼的滞后非线性特性.
Abstract
The hysteresis nonlinearity of a metal mesh vibration damp is studied. A mathematical model of metal mesh vibration damp is established. Parameters of the model are identified with the least square method. The parameters of mathematical model are obtained. It shows that the model can express the non-linear hysteretic character effectively with varied damping characteristic.
