SAIC Motor Technical Center)【Abstract】Instrument cluster vision design flow has been established according to car general layout and related rules and standards with car instrument cluster vision as the study object. CATIA vision checking module that can be used in many different vehicle models has been developed with CATIA secondary development software CAA (building application structure) in accordance with design flow. After the module is used on a new vehicle model, the operation data shows that a blind area is formed on the cluster as a result that the driver’s vision is obstructed by steering wheel hub, wheel spoke and hub when the driver is observing the cluster, therefore, an automatic checking of cluster vision can be realized.Key words: Cluster Vision, CATIA, Secondary Development基于體壓分布信息的乘客識(shí)別系統(tǒng)設(shè)計(jì)研究董恩國 陳亮 秦程現(xiàn)(天津工程師范學(xué)院)【摘要】針對(duì)汽車安全氣囊系統(tǒng)設(shè)計(jì)了輔助控制系統(tǒng)——乘客識(shí)別系統(tǒng)，該系統(tǒng)通過對(duì)座椅壓力傳感器信號(hào)進(jìn)行分析，根據(jù)乘員在座椅上的體壓分布信息識(shí)別乘客體型特征，輔助控制汽車安全氣囊的爆發(fā)。關(guān)鍵詞：AFS；前照燈轉(zhuǎn)角；動(dòng)力學(xué)模型；仿真Dynamic Modeling and Simulative Analysis of Headlight Steering Angle of Adaptive FrontLight System Guan Zhiwei, Cui Huizhong, Zheng fei(Tianjin University of Technology and Education)【Abstract】By using twodegreeoffreedom vehicle linear dynamics model, AFS mathematical model for the turning operation has been established, a system simulation module of this mathematical model has been established in Matlab/Simulink, and a variation curve of headlamp turning angle are obtained under three groups of different variables (under different vehicle speed, front wheel turning angle and turning radius). The simulation results show that the vehicle dynamics has impact on headlamp turning angle in the turning of the vehicle。關(guān)鍵詞：油氣彈簧；可調(diào)阻尼；模型；試驗(yàn)Design and Characteristics Test of Adjustable Damping Valve for Oilgas SpringYang Jie1 Chen Sizhong1 Wu Zhicheng1 Liang Weidong2(1Beijing Institute of Technology。通過臺(tái)架試驗(yàn)對(duì)樣機(jī)進(jìn)行測(cè)試，得到了其速比與執(zhí)行電機(jī)轉(zhuǎn)角的對(duì)應(yīng)關(guān)系以及不同速比下其傳遞轉(zhuǎn)矩和傳遞效率隨帶輪動(dòng)盤夾緊力的變化規(guī)律，從而驗(yàn)證了全電調(diào)節(jié)無級(jí)變速的可行性。與傳統(tǒng)檢測(cè)技術(shù)相比，該檢測(cè)方法具有靈敏度高、壓力控制準(zhǔn)確、自動(dòng)化程度高、使用方便等特性。主題詞：重型載貨車 后橋半軸 非調(diào)質(zhì)鋼 Research on Development and Application of High Performance Nonhardened Tempered Steel for Semiaxle of Automotive Rear AxleLu Yun。采用不同形狀毛坯進(jìn)行了冷擠壓成型工藝試驗(yàn)，指出了成型缺陷的主要影響因素，確定了合理的毛坯及其軟化、潤滑工藝條件，成功地冷擠壓出符合零件技術(shù)要求的高質(zhì)量、高精度冷擠壓件。主題詞：主動(dòng)齒輪 鋸齒形內(nèi)齒 冷擠壓 模具Study on Cold Extruding Forming Technology for the Driving Gear of Sawtooth Inner GearWu Taibin，Kong Fanxin（Nanjing Institute of Technology）【Abstact】In this paper the key technologies including the choice of blank shape and size, pretreatment of blank, the accuracy control of cold extruding die, the structure and quality of punch pin and the choice of die materials etc in the cold extruding process for driving gear of sawtooth inner gear were analyzed. The different blanks were used in cold extruding forming tests, the main influence factors of forming faults were presented and the reasonable softening and lubricating technical conditions of blank were defined, then the cold extruding parts with high quality and accuracy, which satisfied the technical requirement of products, were produced. It was shown by production practice that this cold extruding process was an effective and economic nearnet forming processing technology.Key words： Driving gear。 Wang Ganli。 Air leakage。 Teachers University of Technology)【Abstract】Based on the discussion of advantages and disadvantages of the existing actuation systems for belt CVT, an electrical CVT pulley actuation system is presented with the dual motor regulating the working radius of drive and driven pulley, thus realizing variation of drive ratio, and the rubberVbelt CVT prototype with electrical pulley actuation system is developed.
