解釋
機身阻尼-
Using the simulation method coupling of multi - body and finite element, the simulation model of frontal impact, side impact and car - pedestrian impact of a certain type of vehicle is established by madymo software, and the comparative analysis of impacting performance of the vehicle fitting with or without this equipment is made out. the simulation results show that the vehicle fitting with this equipment has better damping and energy absorption performance. combines with frontal bumper air bag, not only the injury to the occupants and pedestrians in crash accident can be decreased further, but also the damage to the vehicle can be decreased
3 .採用多剛體與有限元耦合的模擬計算方法，利用madymo軟體建立了汽車正碰、側碰及與行人碰撞的模擬模型，對有無該裝置時車輛的碰撞性能進行了比較與分析，結果表明安裝有該裝置時車輛具有更好的緩沖與吸能特性;結合前保險杠安全氣囊技術，不僅可以進一步減少碰撞事故對乘員及行人的傷害，而且可以減少碰撞事故對車輛本身的損壞。 -
This continuous rule can put the suspension system in the optimal damping state. the skyhook principle can be combined in this control rule, which can further attenuate the vibration of the car - body in lower frequency range, but the acceleration response in higher frequency range tend to be larger
文中還研究了把基於天棚阻尼原理的阻尼控制策略結合到該控制系統中的復合控制方法，前者能使系統始終處于最優或次優阻尼，後者則能進一步衰減低頻振動，但也有增大高頻響應的趨勢。 -
The results of simulation show that, compared to the passive suspension system with optimal damping, using continuous damping control rules, the rms values of lateral response acceleration car body can be reduced 20 % to 25 %, maximum values ( 3er ) of lateral acceleration can be reduced 40 % to 50 %, the ride comfort index can be reduced 10 % to 15 %
結果數據表明，與阻尼最優的被動懸掛相比，採用連續型阻尼控制策略，車體橫向加速度響應的均方根值能降低20 - 25 ，加速度最大值能降低約40 - 50 ，橫向平穩性指標降低約10 - 15 。 -
Damping was then determined via exciting the equation at the critical frequency to get the transit decay which was then analyzed with the moving - block method. in chapter 4, the nonlinear dynamic equation of rotor - body system with inter - blade dampers ( taking all possible attachment offsets into consideration, spanwise offset, vertical offset and in - plane offset ) was modeled
本文重點推導了帶葉間減擺器（減擺器帶三個外伸量:展向，垂向和旋轉方向）的旋翼/機體耦合系統的非線性動力學方程，針對該方程提出了一種改進的多槳葉坐標變換方法。 -
Regarding the suspension system as a substructure ( subsystem ) appended on the car body, and considering the vibration transfer effect of the suspension system for the displacement excitation induced by unevenness of road surface, an explicit formula about the quantitative relationship between the sound pressure of low frequency interior noise and some of the suspension characteristic parameters of a vehicle, i. e., the stiffness, the damping, the under suspension mass of suspension system, and the radial stiffness, the radial damping of tire, is deduced based on the dynamic substructure modification method for structure - acoustic coupling analysis of an automobile ' s passenger compartment
摘要基於車身乘坐室聲振耦合的動態子結構修改方法，將汽車懸架系統視為附加於車身上的子結構（子系統） ，並結合懸架系統對路面不平度位移激勵的振動傳遞效應，揭示出車內低頻噪聲的聲壓值與懸架系統剛度、阻尼、非懸掛質量以及輪胎徑向剛度、徑向阻尼間的直接定量關系。
