Shanghai University；2. Shanghai GKN Drive Shaft Co., Ltd. )【Abstract】 The fatigue life tests of needle roller bearing under oscillation working condition were carried out based on intersecting arc trimming needle roller, logarithm profile needle roller and logarithm convex needle roller with different convex values. The tests results show that the lubricating status and carrying capacity of logarithm profile needle roller are better than the ones of intersecting arc trimming needle roller。 Fatigue life鋁合金車身骨架結(jié)構(gòu)T型接頭匹配強(qiáng)度分析張怡1 蘭鳳崇1 陳吉清1 李宇彤2（。 Alalloy。實(shí)例證明，該方法能快速、高質(zhì)量地光順汽車車身復(fù)雜過(guò)渡曲面。 UG。 Complex Transitional Surfaces。 Strength match基于UG的汽車車身復(fù)雜過(guò)渡曲面光順?lè)椒ㄐ旒掖? 李迪 高尚鵬（山東理工大學(xué)）【摘要】討論了UG軟件中過(guò)渡曲面的構(gòu)造方法，根據(jù)汽車車身A級(jí)曲面的要求，給出了各種光順?lè)椒ǖ倪B續(xù)性情況，并以此作為選擇各種方法的依據(jù)。指出,高強(qiáng)度匹配能改善焊接接頭性能，并獲得了高強(qiáng)度最佳匹配系數(shù)，找出了高強(qiáng)度匹配T形接頭焊接結(jié)構(gòu)的薄弱位置。 for a set of needle rollers with same convex value, the carrying capacity under high speed and light load condition is better than the one under low speed and heavy load condition, and the good lubricating status under high speed and light load condition is the main reason.Key words: Convex needle roller bearing。主題詞：液壓動(dòng)力轉(zhuǎn)向器 臺(tái)架試驗(yàn) 標(biāo)準(zhǔn)Study on Bench Test Method of Automotive Hydraulic Power Steering GearQin Quanquan, Liu Jingyang, Hao Jinliang（FAW Haima Automobile CO., LTD）【Abstract】The article takes the rack and pinion hydraulic power steering gear as example and studies the bench test method of six items including empty loaded driving moment test, steering force characteristics test, reverse fatigue test, positive rotation durability test, temperature alternation seal test and noise test, etc..
