Abstract : finite element method of tire temperaturefield is introduced in th is paper . temperature distribution curves of tire 9 . 00r20 underspecific conditio n are given . the results will provide theoretical basis for developingnew tire a nd optimizing tire structures 文摘:介紹了輪胎溫度場(chǎng)的有限單元分析方法,分析了9 . 00r20子午線結(jié)構(gòu)輪胎在特定條件下的溫度場(chǎng)分布情況,給出了溫度場(chǎng)分布云圖和溫度分布曲線,目的是為輪胎的研制開(kāi)發(fā)提供可靠的理論依據(jù),以便優(yōu)化輪胎結(jié)構(gòu)
The main research works and conclusions of this thesis are listed as follows . the dynamic analysis model of elastic mechanism system with damping alloy parts is deduced based on the relationship between stress and strain of the material , also the analysis model under viscous damping model , complex damping model , nonlinear damping model and viscous - elastic damping model is put forward using the finite element method 本文的主要研究工作及結(jié)論如下:從材料應(yīng)力應(yīng)變本構(gòu)關(guān)系出發(fā),導(dǎo)出了滯變阻尼模型、復(fù)阻尼模型、非線性阻尼模型、粘彈性阻尼模型下的有限單元分析模型,進(jìn)而給出了含阻尼合金構(gòu)件彈性連桿機(jī)構(gòu)系統(tǒng)動(dòng)力學(xué)模型。
Which often produces some unexpected problems , such as prolonging time limit of project , increasing engineering quantities and cost , etc . through test on the site , dynamic value analysis , finite element unit method , the paper researchs construction technology of in - situ pile , transfer theory , thickness of supporting layer of head slab and depth of pile in karst area , provides some important conclusions , directs effectively the design and construction of this kind of projects 但因溶洞的分布規(guī)律性差,現(xiàn)有勘探手段難于事先查明它的準(zhǔn)確位置及大小,因而常常給施工帶來(lái)意想不到的問(wèn)題:工期延長(zhǎng)、工程量增加及工程費(fèi)用增加等。本文通過(guò)現(xiàn)場(chǎng)試驗(yàn)、理論計(jì)算和有限單元分析,對(duì)巖溶地區(qū)鉆孔灌注樁的施工工藝、荷載傳遞機(jī)理、持力層頂板厚度及嵌巖深度等方面進(jìn)行了較為系統(tǒng)的研究,得出了一些重要結(jié)論,有效地指導(dǎo)了該類工程的設(shè)計(jì)和施工。
