【文章內(nèi)容簡介】 礎(chǔ)上進一步對散熱器性能進行改善和試驗研究，最終確定了CA6471輕型客車機艙通風(fēng)和冷卻性能改善的設(shè)計方案，解決了其基礎(chǔ)車型CA6440輕型客車因車身結(jié)構(gòu)限制而存在的發(fā)動機過熱問題。主題詞：輕型客車 發(fā)動機艙 冷卻 試驗研究 Improvement of Ventilation and Cooling Performance of Engine Compartment CA6471 Light BusJin Xulong, Yang Xinglong（FAW Group Corporation Ramp。D Center)【Abstract】 Experimental study was made to ventilation and cooling performance of engine partment of CA6471 light duty bus, through which seven measures were defined to improve engine partment ventilation and cooling performance, and the seven measures were further classified and bined into four plans, and the preliminary improvement plan was determined after experimental study. On this basis experimental study was carried out to improve radiator performance, thus the final design plan to improve engine partment cooling and cooling performance of engine partment of CA6471 light duty bus was defined, thus solved engine overheat caused by body structure limit of its basic modelCA6440 light duty bus.Key words：Light bus, Engine partment, Cooling, Experimental StudyCA6700EV純電動客車再生制動控制策略研究劉宏偉 趙文平 呂奉陽( 吉林大學(xué))【摘要】 分析了純電動客車有別于傳統(tǒng)客車的制動特性，論述了制約再生制動能量回收的ECE法規(guī)、需求的電機扭矩、電機的實際峰值扭矩、動力電池SOC值限制等限制條件，提出了適用于本文純電動客車的再生制動控制策略。通過仿真分析，驗證了本文再生制動控制策略的合理性和有效性。主題詞：純電動客車 再生制動 控制策略A Study on Control Strategy for Regenerative Braking for CA6700EV Electric BusLiu Hongwei, Zhao Wenping, Lv Fengyang(Jilin University)【Abstract】 The braking characteristics of electric bus that is different from conventional bus is analyzed, and some conditions that restrict regenerative braking and energy recovery such as ECE law, motor torque demand, motor real peak torque, power battery SOC values, etc. are discussed in the paper, meanwhile regenerative braking control strategy suitable for the electric bus is also presented. Rationality and validity of the regenerative control strategy discussed are validated by simulation and analysis.Key words: Electric bus, Regenerative braking, Control strategy同步帶傳動對發(fā)動機前端噪聲的影響曾慶華1 靳曉雄1 劉波2 （1 同濟大學(xué)；2 奇瑞汽車股份有限公司）【摘要】應(yīng)用發(fā)動機分析專用軟件AVLETD，對某款發(fā)動機的正時同步帶傳動系統(tǒng)進行了一維動力學(xué)仿真，并結(jié)合該發(fā)動機正時系統(tǒng)布置、張緊器匹配和對仿真結(jié)果的分析，提出了系統(tǒng)改進方案。對比方案改進前、后的試驗數(shù)據(jù)與軟件仿真分析結(jié)果表明，采用多體動力學(xué)方法輔助分析可降低由正時同步帶系統(tǒng)振動激勵引起的發(fā)動機正時機械噪聲。主題詞：發(fā)動機 正時同步帶 傳動 噪聲Effect of Synchronous Timing Belt Transmission on Engine NoiseZeng Qinghua1, JinXiaoxiong1, Liu Bo2（1 Tongji University 2 Chery Automobile Co., Ltd）【Abstract】1D dynamic simulation for the synchronous timing belt transmission system of an engine is carried out with special purpose engine software AVLETD, an improvement program is proposed according to layout of engine timing system, tensioner match and analysis of simulation results. Comparison of the test data prior and after the test as well as analysis of software simulation indicate that the CAE with multibody dynamic method can reduce engine timing mechanical noise caused by vibration and excitation of the synchronous timing belt transmission system..Key words：Engine Synchronous timing belt Transmission Noise轎車懸架橡膠襯套結(jié)構(gòu)特點分析余振龍 具龍錫 （一汽轎車股份有限公司）【摘要】介紹了橡膠襯套的種類,闡述了汽車懸架橡膠襯套的基本性能及其應(yīng)用情況。研究了懸架的副車架橡膠襯套和控制臂橡膠襯套在車輛中各向特性參數(shù)的分布及其對汽車操
