A variable damping system is conceived and designed 构思设计了一种可变阻尼系统。
The damper with dynamically variable damping properties is one of the key elements for semi - active suspension systems 半主动控制悬架系统的关键之一是可实时调节的阻尼器。
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 也就是说,变阻尼控制效果的好坏并非仅仅取决于结构的周期(柔性结构或刚性结构) ,而主要取决于结构周期与激励主周期的比值。
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 在大多数情况下,粘性变阻尼控制与无控相比可以显著减小结构的动力反应,但与相应的被动上限阻尼控制相比并不能进一步改善控制效果,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 近年来,一种由高科技亚纳米材料?磁流变体制成的磁流变智能阻尼器( magneto - rheological ( mr ) damper )问世并用于实际工程减振,该阻尼器的阻尼特性随输入电压的变化而改变,具有良好的可变阻尼特征,可实现半主动控制。
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,以某发动机悬置的设计为背景,比较了各种设计方法,论证出半主动连续可控阻尼悬置为最佳的方案,并用简化的悬置模型进行了数值仿真分析,通过得到的振动性能的比较,表明按天棚阻尼设计的连续性半主动悬置系统,能够有效地隔离发动机振动,有很好的工程应用前景。
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, _上述四种不同的控制体系中,基底隔震上部半主动变刚度变阻尼控制体系( bl & avsd )能稳定有效地减少上部结构层间位移,具有较好的减振效果。
