A variable damping system is conceived and designed 構(gòu)思設(shè)計了一種可變阻尼系統(tǒng)。
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(tǒng)的關(guān)鍵之一是可實時調(diào)節(jié)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(jié)構(gòu)的周期(柔性結(jié)構(gòu)或剛性結(jié)構(gòu)) ,而主要取決于結(jié)構(gòu)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(shù)情況下,粘性變阻尼控制與無控相比可以顯著減小結(jié)構(gòu)的動力反應(yīng),但與相應(yīng)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(xiàn)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(fā)動機懸置的設(shè)計為背景,比較了各種設(shè)計方法,論證出半主動連續(xù)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(shù)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(shè)計的連續(xù)性半主動懸置系統(tǒng),能夠有效地隔離發(fā)動機振動,有很好的工程應(yīng)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(wěn)定有效地減少上部結(jié)構(gòu)層間位移,具有較好的減振效果。
