In these equations , the compression wave propagation and the transverse inertia effect were taken into consideration 通過引入圓柱殼動力失穩(wěn)時的波前約束條件實現(xiàn)了此類問題的有限元特征值解法。
From the numerical analysis results of this paper , one finds that the inertia effect of the spring do affect the vibration reduction effectiveness of the absorber to some degree 由本文所提出的?值分析結果,吾人發(fā)現(xiàn),避振器的彈簧慣性效應對避振器的減振效?有某一程?的影響。
Unlike the existing literature that the absorber was considered as a spring - damper - mass system and the inertia effect of the spring was neglected , the last effect was taken into consideration in this paper 在現(xiàn)有文獻中,研究學者通常用彈簧阻尼質?系統(tǒng)?替換避振器,并且將避振器的彈簧慣性效應加以忽? ?計,本文則將上述慣性效應加以考慮。
The paper tests tracks " dynamic responses by using euler beam model with no accounts of shear and rotary inertia effects and timoshenko model with consideration of shear and rotary inertia effects respectively 不考慮軌道的幾何不平順,不考慮阻尼,分別采用不考慮剪切效應和轉動慣量作用的euler梁模型和考慮剪切效應和轉動慣量作用的timoshenko梁模型對軌道動力響應進行了模擬。
There is especial systematic background to build up small towns in china . it cannot help but choose small towns " building - up under the condition that planned economic system makes deviation of economic structure of industrialization advancing urbanization , the large number of labor in countryside , and the chance of job is lack in cities . so the systemic barriers in small towns " building - up is the inertia effect of planned economic system 我國小城鎮(zhèn)建設具有特殊的體制背景,它是為了矯正計劃經濟體制下形成的“工業(yè)化超前、城鎮(zhèn)化滯后”的經濟結構偏差和解決我國農村勞動力數(shù)量巨大、大中城市就業(yè)需求不足而提出的,是提高我國城鎮(zhèn)化水平必然而無奈的選擇,因而小城鎮(zhèn)建設的體制性障礙是計劃經濟體制的體制慣性作用,具有政策剛性、交叉性綜合性和動態(tài)性等特征。
