Test results showed that the fatigue limits of the rolled specimen s could be increased by 175％ or so if the proper allowance of finish grinding a nd the optimum parameters of fillet rolling were elected, with the bending fatig ue stresses at the pin fillets being up to 552～ 605 N/mm2. Therefore, finish gr inding had little effect on the fatigue strength of crankshaft rolled after semi －finish machining.     对两种型号曲轴的半精加工圆角滚压工艺和疲劳强度进行了研究，结果表明，选择合 适的精磨余量和滚压工艺参数，曲轴疲劳强度可提高 175％左右，圆角处疲劳极限应力达 5 52～ 605 N/mm2，曲轴的疲劳强度较之精磨后滚压没有下降。 短句来源   “fillets”译为未确定词的双语例句     Strengthening Crankshaft Fillets of Diesel Engines by shot Peening     柴油机曲轴圆角喷丸强化新技术 短句来源   相似匹配句对     Strengthening Crankshaft Fillets of Diesel Engines by shot Peening     柴油机曲轴圆角喷丸强化新技术 短句来源     Applying the deep rolling depression technology to engine crankshaft fillets can greatly improve their fatigue strength.     发动机曲轴圆角采用深滚压工艺可大幅提高曲轴疲劳强度。 短句来源 查询“fillets”译词为用户自定义的双语例句     我想查看译文中含有：的双语例句 为了更好的帮助您理解掌握查询词或其译词在地道英语中的实际用法，我们为您准备了出自英文原文的大量英语例句，供您参考。   fillets In storage on ice, fillets of fish fed the diets high in α-tocopheryl acetate exhibited significantly lower (P>amp;lt;0.05) levels of oxidation. 例句来源       These results suggested that increased dietary α-tocopheryl acetate could increase its flesh deposition, increase the activity of SOD and prevent lipid peroxidation of Sparus macrocephalus fillets in retail storage on ice. 例句来源       The peak stresses appeared at the slot corners inside the adhesive fillets and at the horizontal and vertical plate outer fibres corresponding to the two slot free ends. 例句来源       High stress concentrations were observed around the adhesive free ends and the peak adhesive stresses occurred inside the adhesive fillets. 例句来源       The steady state heat transfer analysis showed that the temperature distribution through the joint members was non-uniform and high heat fluxes occurred inside the adhesive fillets at the adhesive free ends. 例句来源       更多                    This paper describes the mechanism and parameter determination of shot peening on crankshaft fillets, and discusses the significant achievement in improving the fatigwe strength of crankshaft by this way             本文介绍了曲轴圆角喷丸技术的机理和参数的确定,并论述了曲轴圆角喷丸强化后,对提高曲轴疲劳寿命的重要作用。 文摘来源          The bending and torsional fatigue stength of a model 6100 engine crankshaft is tested on a DC-1 electrical resonance type fatigue testing machine using up and down experimental method.
