| 摘 要： | 用金属丝网减振器非线性滞回特性,将滞迟恢复力进行分解,并由此建立随振动幅值和频率变化而变化的非线性数学模型。通过正弦加载试验获得各工况下的数据样本,对模型参数进行辨识,并验证其合理性。由耗能等效原则,对金属丝网减振器响应进行近似解析求解,检查其精度。为金属丝网减振器建立满足工程需求和反映实际工况的数学模型和响应计算提供了可行方案。

| Abstract: | Using the nonlinear hysteretic characteristics of metal-net damper, making the hysteretic restoring force decomposed, and established changing over vibration amplitude and frequency of nonlinear mathematical model, by sinusoidal loading test data under various operating conditions to obtain samples, identified the model parameters, and verified them rationality. By means of the equivalent principle of energy dissipation, the response of the metal-net damper solved by approximate resolution, and checking the accuracy. It provides a feasible solution to the mathematical model and response calculation, which could meet the engineering requirements and reflect the actual condition. |
