negative damping meaning in English
负阻尼
Examples
- According to these theories we know the reason of the emergence of low frequency oscillation is lacking positive damping even appearing negative damping . this problem can be classified as dynamic stability
从而得出，电力系统低频振荡是由于系统正阻尼不足甚至产生负阻尼而引起的，可以将其归类为动态稳定问题。 - Those sensitive parameters making system have negative damping and occur self - excited shimmy are horizontal pulling lever rigidity , tire sideslip rigidity , steering gear rigidity and damping , kingpin equivalent damping , kingpin caster angle , tire drag . and wheel center distance , tire side rigidity , vehicle wheel unbalanced mass , tire vertical rigidity , and distance from kingpin center to the vertical central line plane of tire have great influence on shimmy , but they do n ' t make the system have negative damping . and horizontal pulling lever damping , suspension damping and rigidity have very small influence on shimmy
横拉杆刚度、轮胎的侧偏刚度、转向机刚度、转向机阻尼、绕主销当量阻尼、主销后倾角、轮胎拖距是影响摆振的敏感性参数，适当调节某一参数可引起系统的负阻尼，使系统产生自激摆振；轮距、轮胎侧向刚度、车轮上的不平衡质量、轮胎垂向刚度及主销延长线与地面交点至车轮平面的距离对摆振的影响也较大，但不会使系统出现负阻尼；而横拉杆阻尼、悬架阻尼与悬架刚度对摆振的影响很小。 - To reproduce the narrow - band response , based on the thought of kanamori etc . , the damping ratio and natural period are modified . through this adjustment , the narrow - band response can be reproduced , but for some natural periods the adjustive damping ratio has become negative . the negative damping is strange and can not be explained by the equation of motion for sdof system
为了生成窄频带反应，本文根据kanamori等人的方法调整了计算时的阻尼比及自振周期，调整后的单边差分方法能在共振区域生成很好的窄频带反应，但是对一些周期点的阻尼比调整成为了负值，这从系统的动力平衡方程是难以解释的。
