中文拼音 [děngjiàzǔní]
等價阻尼
英文
equivalent damping-
Using the dynamic mechanical analyzer ( dma ), pdms / pma ipn was investigated at temperature of 5 - 180 c. the initiator, the component ratio, the type of pdms and the filler effected the damping properties. the result showed that the damping ability varied with the parameter and there was an optimal value. the excellent damping material in the papers was ipn, where tan man was 0. 735, and the damping functional temperature ranged with tan 8 > 0. 3 was 46 c. the micro - morphology and structure of pdms / pma ipn were characterized by two kinds of sem
高分子阻尼材料的有效阻尼功能區是在ipn材料的t _ g區間內，而研究常溫條件下的阻尼性能更具有重要應用價值，運用動態熱機械分析（ dma ）儀對ipn阻尼材料進行表徵，在5 180內對其損耗因子（ tan ）進行研究，發現引發劑和交聯劑的用量、聚硅氧烷的用量和分子量等參數對ipn阻尼性能的影響較大，存在一個合理配比值，當pma與粘度為3300pa ? s的pdms之比（質量比）為1 . 17 ： 1 、交聯劑用量為1時， tan最大值為0 . 735 ，大於0 . 3的溫域差達到46 。Currently, researchers from home and abroad usually use simplified models in the aseismatic analyses of immersed tunnels, which can not properly simulate the two functions of the soil, while the finite element method solves this problem successfully, and the development of numeric calculation and computer technology lays a solid basis for its application, it is a pity that the applications of fem is not common currently
目前，國內外對沉管隧道進行抗震分析時，大多採用簡化計算模型，將土的作用以等價彈簧和阻尼器代替，不能適當模擬土既是地震波的傳播介質又是結構物的支承介質的雙重作用。動力有限元法的連續介質模型很好的解決了這一問題，數值計算理論和計算機技術的發展為該方法的應用奠定了堅實的基礎，然而，目前這方面的應用還很少。In order to find out the speciality of the hysteretic system under random excitation, random responses and model parameters of hysteretic system were studied by the method of stochastic equivalent linearization and mento - carlo simulation
為了更好地了解在隨機激勵作用下遲滯阻尼振動系統的動力學特性，本文將隨機等價線性化法與monto - carlo法應用於遲滯阻尼振動系統隨機響應分析並對該系統的參數特性進行了初步的研究。According to regress, the paper got equivalent shearing stiffness and equivalent damping gene ' s calculating formula of the hdr ' s equivalent linear model. at last, the paper estimates the effect of integrated isolation bearing with a 4 span continuous beam bridge by nonlinear dynamic analysis program
根據能量相等的原則，本論文提出了高阻尼橡膠剪切滯回曲線的雙線性模型和模型中各參數的計算公式；回歸出了用剪應變表示的等價線性化模型的等價剪切剛度和等價阻尼比實用計算公式。The mento - carlo simulation was introduced to substitute the random vibration experiment. the random responses of hysteretic system gotten by the method of stochastic equivalent linearization were compared with mento - carlo simulations, and the feasibility of this method was exemplified by mento - carlo simulations
對于遲滯阻尼振動系統的非平穩響應，本文亦用monte - carlo法來代替隨機振動實驗進行了計算求解，並與隨機等價線性化方法進行了比較與分析，例證了等價線性化方法處理遲滯阻尼振動系統隨機響應的可行性。The design of vehicle suspension system must be adapted to the requirement of the ride comfort and the control stability. it ' s difficult for traditional passive suspension to enhance the ride comfort. however, semi - active suspension can meet the ride comfort well because its suspension parameters such as damp coefficient or spring firmness can be adjustable
車輛懸架系統的設計必須適應行駛平順性和操縱穩定性的要求，傳統的被動懸架系統已無法從結構設計上使車輛具有良好的平順性，而半主動懸架由於其懸架參數如阻尼、彈簧剛度等具有可調性，使得它可以很好地滿足車輛行駛過程的需要，同時與主動懸架相比，由於工作中幾乎不消耗發動機的功率，結構簡單，造價較低，因此受到車輛工程界的廣泛重視。分享友人
