damping angle
解釋
阻尼角度-
The rudder roll damping system is just the system whose controlled object is not square matrix. the input is rudder - order and the outputs are the roll angle and the heading angle. the input controls the two outputs
舵阻搖系統正是被控對象為非方陣的系統，它通過輸入_ r （舵令）來控制輸出（橫搖角）和（首向角） 。 -
This provides an increased damping rate and allows a slight reduction in camber angle
這樣就增加了減震度，並且可以稍微減少外傾角。 -
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
橫拉桿剛度、輪胎的側偏剛度、轉向機剛度、轉向機阻尼、繞主銷當量阻尼、主銷后傾角、輪胎拖距是影響擺振的敏感性參數，適當調節某一參數可引起系統的負阻尼，使系統產生自激擺振；輪距、輪胎側向剛度、車輪上的不平衡質量、輪胎垂向剛度及主銷延長線與地面交點至車輪平面的距離對擺振的影響也較大，但不會使系統出現負阻尼；而橫拉桿阻尼、懸架阻尼與懸架剛度對擺振的影響很小。 -
The electrical damping within the whole subsynchronous frequency range is calculated. the impacts of the unit interaction factor between hvdc and turbine generator, the dc power level, the firing delay angle and the parameter settings of hvdc controller on the have the potential danger of subsynchronous oscillation
在整個次同步頻率范圍內，計算得到了系統電氣阻尼，並詳盡地分析了同步發電機與hvdc的耦合程度、直流輸送功率水平，換流閥觸發角大小以及控制器參數等因素對系統電氣阻尼的影響。 -
In order to overcome these problems, the prony method based on angle measurement technology is used. it " s ability to estimate the frequency, damping and strength of modal components would be quite valuable to power system research. 2
據此研究使用prony方法直接分析測量信號、提取特徵振蕩模式的方法，並結合前後兩種方法分析兩者之間的聯系，從理論上分析了prony方法的有效性。 -
Then, the hilbert transform is applied to each modal response to obtain the instantaneous amplitude and phase angle time histories. a linear least - square fit procedure is proposed to identify the natural frequency, damping ratios, physical mass, damping and stiffness matrices from instantaneous amplitude and phase angle for each modal response
然後對各階模態響應進行hilbert變換，得到瞬態幅值和相位角的時間歷程，再運用線性最小均方擬合來識別自然頻率、阻尼比、質量、剛度和阻尼矩陣。 -
The deformation characteristics of pavement section and soft soil subgrade under traffic load are analyzed, considering the effects of load ( including type, amplitude and frequency ) and parameters of soft soil ( including resilient modulus, cohesion, internal friction angle, poisson ratio, damping ratio et al )
