  1. As a part of the civil 863 plans, two multiple - contact models for two kinds of braking system are built in the paper, in which contact fields are described as coons surfaces, initial velocity is programmed in fortran. the thermal - mechanical coupling braking processes are simulated for the first time by msc. marc, the general - used nonlinear fem software. time distributions of the velocity, the stress and the temperature of the components under various initial velocity and brake force are obtained, which offer theoretic gist to study the life of the wheel, the disc and so on

    作為國家行業863重大課題《鐵路機車車輛虛擬樣機系統》的一部分,本文在研究接觸問題和熱?機耦合問題數值方的基礎上,採用國際上通用的線性有元分析軟體msc . marc建立了踏面動和盤形動主要部件的多體接觸計算模,其中用解析方描述,即用nurb曲線、高斯曲面來描述接觸區域,用fortran言編寫定義初速度的用戶子程序,首次對兩種動過程熱?機耦合進行了數值模擬,定量給出了主要動部件在不同初速度、不同動力下各個時刻的速度、應力和溫度的變化規律,為研究車輪、閘瓦以及動盤壽命提供了理論依據。
  2. Using 3d 20 - node iso - parameter, 3d 12 - node infinite element and 3d 16 - node interface element, a coupled numerical approach for pile group - soil system under lateral loads is set up. a corresponding three - dimensional, nonlinear and elastic - plastic program ( epagpll ), include two materials and four nonlinear constitutive relations, is worked out by fortran 90 computer language. in the analysis the nonlinear e - model, k - g model and cambridge model with two yield surfaces are employed in the analysis of near - field soil, and the nonlinear analysis method is used in the piles - soil interface and distant - field soil

    本人用有元進行樁體和近域土的分析,對遠域土體採用無單元,在樁土之間採用接觸面單元,建立了平面8節點環狀單元6節點無元6節點接觸面單元相耦合的數值計算模;針對豎直受力樁的流變分析,本人用內嵌于autocad的vba言編了前處理程序,可以快速形成包括網格、節點編號、單元編號在內的數據文件,供計算程序使用;同時在前人關于流變問題研究的基礎上,引進土體線性流變本構模,利用有元、無元、接觸面單元相結合的方,用c + +言編了相應的計算程序。
