  • 摩擦熱

Examples

  • This depends on the estimation of the temperatures generated by frictional heat .
    它取決于摩擦熱所引起的溫度估算。
  • The result shows that it is mainly caused by the martensite with high hardness produced after rail absorbing frictional heat
    斷裂的主要原因是鋼軌在吸收摩擦熱后產(chǎn)生了高硬度的馬氏體。
  • The biggest fuel savings achieved by a full hybrid vehicle derives from regenerative braking , a technology that captures as electrical power much of the energy normally lost as frictional heat
    高量級混合車最大的省油關(guān)鍵來自再生制動(dòng)（煞車）技術(shù)，這種技術(shù)可捕集摩擦熱（通常幾乎散失掉的能量）并轉(zhuǎn)變成電力。
  • The effect of the variation of temperature and contact pressure of the sliding contact surfaces with frictional heating on each other , particularly the relationship of the applied pressure and the contact pressure and the effect of the separate variation of some parameters on the simulation results were taken account into in the course of numerical simulation
    在數(shù)值計(jì)算過程中，著重考慮了溫度變化與接觸區(qū)域壓力變化的耦合問題，接觸壓力與外加壓力的關(guān)系，以及分別改變一些參數(shù)對結(jié)果的影響。
  • The fem results indicated that as to the rough surfaces in sliding contact , the value of the contact pressure was very high which coursed a high value of the heat flow rate , meanwhile the sliding time was not enough for the frictional heat to transfer , thus the highest value of the body temperature occurred just on the sliding surfaces , which possessed a sharp thermal gradient in direction perpendicular to the sliding surface . so the great thermal stress was caused just by the sharp gradient and the thermal elastic distortion with which the contact pressure changed occurred simultaneously , thus this change of the contact pressure would affect the temperature distribution in return
    對于相對滑動(dòng)的粗糙表面，因?qū)嶋H接觸面積小而導(dǎo)致接觸壓力很大，這樣使得熱流密度會(huì)很大，同時(shí)由于滑動(dòng)時(shí)間很短，熱來不及傳導(dǎo)，最高溫度發(fā)生在摩擦表面，在垂直于摩擦面的方向有很大的溫度梯度，使得熱應(yīng)力很大，且最大應(yīng)力發(fā)生在表面，同時(shí)產(chǎn)生熱彈性變形，這種變形使得接觸區(qū)域內(nèi)的壓力分布發(fā)生變化，這種變化又反過來影響了接觸區(qū)域的溫度分布。
  • Based on g - w contact model , two rough surfaces in contact were simplified to a smooth one and a rough one which has regular rectangular asperities , and a three - dimensional transient thermal and stress coupled fem model was established using thermal - structure sequential coupling . the course of the sliding with friction was simulated using the nonlinear multiphysics field fem , meanwhile considering thermal - elastic problems of the two bodies , to calculate and analyze the temperature , contact pressure and stress of the sliding contact surfaces with frictional heating
    基于g - w接觸模型，將兩個(gè)粗糙表面簡化為一個(gè)有規(guī)則排列的長方體微凸體的粗糙表面與一光滑表面，利用熱結(jié)構(gòu)順序耦合建立三維瞬態(tài)有限元計(jì)算模型，考慮兩個(gè)物體摩擦接觸的熱彈性問題，采用非線性有限元多物理場來實(shí)現(xiàn)，對粗糙表面接觸模型的瞬時(shí)摩擦溫度場、壓力場和應(yīng)力場進(jìn)行了計(jì)算分析。
  • Based on the theories of gear engagement , contact analysis , friction and heat transfer , a three - dimensional finite element model of gear tooth was established to investigate temperature distributions and variations along the contact path over a range of applied loads and operating speeds with consideration of lubrication conditions . sensitivity analysis of surface temperature to gear configuration , frictional heat flux , heat transfer coefficients , and oil and ambient temperature was conducted and the major parameters influencing surface temperature were evaluated
    本文基于齒輪嚙合原理、輪齒接觸分析、摩擦學(xué)和傳熱學(xué)，以有限元分析方法和理論分析計(jì)算相結(jié)合為手段并以實(shí)驗(yàn)測量結(jié)果作為參考，建立了適用于工業(yè)應(yīng)用并具有較高計(jì)算精度的高速齒輪傳動(dòng)輪齒溫度分析的模型和方法，系統(tǒng)地分析了輪齒本體溫度的大小和分布以及齒輪幾何、載荷及轉(zhuǎn)速和潤滑冷卻條件等對輪齒本體溫度的影響。
  • Many kinds of the heat sources ( frictional heat , cutting heat , ambient temperature , etc ) in machining system produce a kind of temperature distribution . this temperature distribution induces thermal deformation between machine tools , tool , work - piece and work holding fixture . this deformation affects the relative displacement between the work piece and the cutter , causes the manufacturing errors , and influences the machining accuracy of the work - piece
    在機(jī)械加工中，工藝系統(tǒng)在各種熱源(摩擦熱、切削熱、環(huán)境溫度、熱輻射等)的作用下，產(chǎn)生溫度場，致使機(jī)床、刀具、工件、夾具等產(chǎn)生熱變形，從而影響工件與刀具間的相對位移，造成加工誤差，進(jìn)而影響零件的加工精度。
