【摘要】：对双线性滞迟振子的无谐振机理进行了理论和试验研究。建立干摩擦阻尼隔振系统力学模型,对其低频锁止特性进行了研究,并由此得到解锁频率的解析解,确定了最优解下的系统参数关系;利用运动方程对系统时间响应过程进行了深入的数值计算,并通过试验对理论结果进行了验证。所得结论对无谐振隔振器的合理设计具有指导意义。
[Abstract]:The resonant mechanism of bilinear hysteretic oscillators is studied theoretically and experimentally. The mechanical model of dry friction damping vibration isolation system is established, and the low frequency locking characteristic is studied. The analytical solution of unlocking frequency is obtained, and the system parameter relationship under the optimal solution is determined. The time response process of the system is numerically calculated by using the motion equation, and the theoretical results are verified by experiments. The conclusion is of great significance to the rational design of the non-resonant vibration isolator.
