測定潤滑油對改進二沖程循環汽油發動機預燃傾向的標準試驗方法In this paper, by using non - linear finite element software, ansys / ls - dyna, simulate a forming of auto fall to ground skeleton part, get the contour of the semi - finished product, forecast the change of the blank thickness and the probable wrinkling, cracking, and from the simulation of the spring - back, obtain the spring - back tendency. so, get technology parameters, which are inextricable to forming production. all these will pose great significant to production in theory and reality
本文運用非線性有限元軟體ansys ls - dyna對汽車落地骨架零件進行了沖壓成形的數值模擬，得出了毛坯外形，預測了成形過程中板料壁厚變化和可能出現的起皺、破裂現象，通過回彈模擬，預測了回彈趨勢，獲得了該類零件成形所需要的工藝參數，對實際生產具有一定的指導作用。In the text, there analyzes the process of the mixture air and fuel in the two stroke gasoline engine and bring forward the specific solution to the improvementsing gasoline engine the high - press direct in - cylinder injection. this technology sprays the feul into the cylinder after the outlet vavle closed and scavengs the engine cylinder with pure and fresh air, which avoid the fuel escapes unburned
本文分析了二沖程汽油機混合氣形成過程，並提出了具體的改進方案，用缸內高壓直接噴射技術進行改造。缸內高壓直接噴射是在發動機排氣口關閉後向氣缸內噴射燃油，使用純新鮮空氣進行掃氣，避免了燃油短路損失。It is based on a set of practical data in some area. the nonlinear least - square method is used to work out the parameters of the mobile communication channels " model, and then the error sequence comes into being. the noise ' s model of automobile that can reflect the random characteristics of the noise is also founded
本論文採用簡單分群的markov二狀態模型建立移動通道概率統計模型，從某一移動通道實測曲線出發，利用非線性最小二乘法得出狀態模型參數，從而獲得移動通道的差錯序列；本文對汽車噪聲的產生以及它對信號的影響進行了詳細的分析，提出了汽車噪聲模型；並且採用尖脈沖模擬汽車點火噪聲脈沖，實現了噪聲對信號的隨機干擾，形象地反映了移動通道中信號的疊加過程。The engine is tested on the dynometer using the software that can monitor the ecu ( electronic control unit ) internal dataflow. and the electronic control fuel injection system parameters ( e. g. position of throttle valve, engine speed, air temperature, engine temperature, duration of injection ) are acquired at many different working conditions of engine
本文以hirth3203二沖程汽油發動機為研究對象，利用開發的ecu內部動態數據流監測軟體進行發動機臺架試驗，獲取了在不同的油門開度和轉速下電控燃油噴射系統的一系列工作參數，如節氣門開度、發動機轉速、進氣溫度、氣缸溫度、蓄電池電壓以及噴油脈寬。Comparatively, the molecular dynamic ( md ) can overcome these shortcomings and can be applied in the research of adsorption in the nanopores. this study mainly includes two parts, one is the study on adsorption equilibrium in cylindrical nanopores, and the other is that on the adsorption in carbon - nanotubes. in the first part, a new potential model is introduced, and the isotherms for different nano - pore diameters are obtained
對于不考慮固體壁面分子結構的圓柱形納米微孔的平衡吸附，建立了包括勢緩沖區在內的單元體模型，引入了表示整個微孔壁面與吸附質分子相互作用的新型壁面勢方程，並對3 - 5nm孔徑圓柱型微孔中的平衡吸附進行md模擬，得到了在不同汽相壓力下的分子位形圖譜及相應的吸附等溫線並對其進行了分析。分享友人
