1.On the basis of reference (superscript [6]), the influence of damping of shimmy damper, moment of inertia of wheel, tire cornering stiffness and strut tilt stiffness on parametric shimmy stability of aircraft wheel is investigated in the paper.
摘要本文在文献[6]的基础上,首次研究了减摆器阻尼、机轮转动惯量、轮胎偏滚刚度、支柱侧倾刚度对飞机机轮参数摆振稳定性的影响。
2.This paper assumes that the top of nose wheel strut is fixed and gives the complete nonlinear equations used to describe the shimmy system with six degrees of freedom. The harmonic equilibrium method are used to study of stability of the nose wheel shimmy system with considering the effect of strut stiffness and coulomb friction as well as the nonlinear damping.
假设前起落架支柱上端固支,并且给出了用以描述六自由度的前轮摆振运动的非线性微分方程组,使用谐波平衡法研究了考虑支柱弹性影响,具有库仑摩擦及非线性阻尼的前轮摆振系统的稳定性问题。
3.Now, an entire season stretches out before the man who earned his nickname by shaking off defenders with a shimmy of his shoulders during eight years in the NBA.
现在,整个赛季的比赛强度愈来愈大。在这之前,布莱恩特在他过去八年的NBA职业生涯里都是以他独有的突破性上篮而摆脱掉对手的防守而出名的。
4.The results obtained in this paper prepare the ground for the design of new aircraft and for the safe maintenance of aircraft in service to prevent the occurrence of shimmy.
本文所得结论对于新机防摆设计和现役飞机的防摆维护有一定参考价值。
5.This paper investigated the limit cycle amplitude of nonlinear shimmy system withthe nonlinear damping M_(0_1)=C_1θ_1+C_dθ_1~2sgn(θ_1)and with five degrees of freedom by describing functionmethod and by perturbation method when taxing speed exceeds a critical speed.
_1=C_1θ_1+C_(?) θ_1~2sgn(θ_1)的五自由度前轮非线性摆振系统,当超过飞机临界滑跑速度时极限环幅值的变化规律,并用数值分析方法予以验证。
6.It can samba one moment, shimmy to a Monkees? style pop chorus the next or writhe to exotic Middle Eastern melodies.
它一会儿是桑巴舞曲,一会儿变成现代流行的Monkees风格的合唱或是中东悦耳的异域风情。
7.Once the Prince gets a good lay of his land, he can climb, swing, run, vault, roll, scurry, shimmy, and dangle his way into a position that grants him an advantage over his opponents.
一旦王子到达了合适的地点,他就可以通过攀爬,悬摆,助跑,跳跃,疾走,摇动,悬荡等各种动作让自己处于一个好位置,占据主动。
8.A suggestion is also made that the damping and stiffness of steering system should be appropriately increased to reduce or even eliminate the occurring of front wheel shimmy.
在一定的参数组合下,具有不同转向特性的汽车都或多或少地存在摆振现象,这与实际情况相符,建议适当增加转向系阻尼和刚度以减小甚至消除摆振的发生。
9.A burst of pace and a shimmy later, he was lining up a left foot shot that Van der Sar did well to parry clear.
然后他用速度和假动作过掉维迪奇,左脚劲射,好在范德萨力保球门不失。
10.If anything, a bit of weight in the front panniers calms the steering, and contrary to occasional user reports of steering shimmy, I found it stable and secure at speed.
偶而有车主反映操控时的不稳定感,此时若把前马鞍袋加些重量后,行进间就会变稳定。
