A variable damping system is conceived and designed 構思設計了一種可變阻尼系統。
The damper with dynamically variable damping properties is one of the key elements for semi - active suspension systems 半主動控制懸架系統的關鍵之一是可實時調節的阻尼器。
In other words , the effectiveness of viscous variable dampers on reducing the response of structures depends on not the period of the structure , i . e . the rigid structure or the flexible structure , but the ratio of the disturbance period to the structure 也就是說,變阻尼控制效果的好壞并非僅僅取決于結構的周期(柔性結構或剛性結構) ,而主要取決于結構周期與激勵主周期的比值。
The results indicate that while variable dampers significantly reduce the response as compared to the case with no control , no reduction or the worse situation is observed when compared to the same device acting as a passive damper with the upper limit of the damping of the corresponding variable damper 在大多數情況下,粘性變阻尼控制與無控相比可以顯著減小結構的動力反應,但與相應的被動上限阻尼控制相比并不能進一步改善控制效果,甚至有所不及。
In the recent years , a new smart damper , magnetorheological ( mr ) damper , is developed for vibration control , which is made of smart mr fluid . mr damper has an excellent variable damping property and its damping force can be changed by adjusting voltage applied to damper . therefore , semi - active control can be implemented with the damper 近年來,一種由高科技亞納米材料?磁流變體制成的磁流變智能阻尼器( magneto - rheological ( mr ) damper )問世并用于實際工程減振,該阻尼器的阻尼特性隨輸入電壓的變化而改變,具有良好的可變阻尼特征,可實現半主動控制。
In addition , taking one engine mounts design into account , the paper investigates and compares some types of design schemes and shows that semi - active continuous variable damper is feasible and applicable . the numerical simulation results further proves that the continuous variable sky - hook damper is able to effectively isolate the engine vibration , so the damper has promising value in the engineering field 另外,以某發動機懸置的設計為背景,比較了各種設計方法,論證出半主動連續可控阻尼懸置為最佳的方案,并用簡化的懸置模型進行了數值仿真分析,通過得到的振動性能的比較,表明按天棚阻尼設計的連續性半主動懸置系統,能夠有效地隔離發動機振動,有很好的工程應用前景。
In this paper , another three control systems were also discussed . they are base - isolation system ( bi ) , base - isolation & passive variable stiffness system ( bi & pvs ) and base - isolation & passive variable damping system ( bi & pvd ) . these control effectiveness of four control systems are all computed and compared 分析表明, _上述四種不同的控制體系中,基底隔震上部半主動變剛度變阻尼控制體系( bl & avsd )能穩定有效地減少上部結構層間位移,具有較好的減振效果。
