【摘要】:對雙線性滯遲振子的無諧振機理進行了理論和試驗研究。建立干摩擦阻尼隔振系統(tǒng)力學模型,對其低頻鎖止特性進行了研究,并由此得到解鎖頻率的解析解,確定了最優(yōu)解下的系統(tǒng)參數(shù)關(guān)系;利用運動方程對系統(tǒng)時間響應(yīng)過程進行了深入的數(shù)值計算,并通過試驗對理論結(jié)果進行了驗證。所得結(jié)論對無諧振隔振器的合理設(shè)計具有指導意義。
[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.
