本文采用有限元仿真方法,根据国标GB15083—2006,汽车座椅、座椅固定装置及头枕强度要求和试验方法,的相关规定,对某国产车型后排座椅骨架的模型进行搭建,利用非线性求解器LS-dyna对其进行求解.找到仿真失效的部件,并通过提高材料、增加厚度和改进结构的方式进行优化,最终改进结构的方案达到了预期的效果.通过试验对最终优化的结果进行了验证.结果表明试验和模拟仿真在结构变形上基本是吻合的,并且座椅靠背和头枕均未超过规定平面,因此该座椅是满足此项法规要求的.最后根据参数化建模对座椅靠背铰链结构进行灵敏度分析,找出能够提升铰链强度的有效途径,为后期车型改款奠定基础.

二级可调增压柴油机高海拔性能模拟研究

建立基于VGT的二级可调增压柴油机高海拔工作过程仿真模型,研究了不同海拔、不同工况下VGT叶片调节特性,并通过优化,得到了VGT叶片开度最佳MAP,在此基础上,进行了二级可调增压系统与柴油机不同海拔匹配性能研究.结果表明:高、低压级增压器与柴油机匹配效果较好,在海拔5500m,除怠速工况外,其余各工况的工作点均处于压气机高效率区.与单级增压柴油机相比,二级可调增压系统总压比随海拔的升高而增大,在海

油品升级对GDI发动机燃烧及排放的影响

在一台GDI发动机上进行油品升级试验,研究油品升级前后不同油品对GDI发动机燃烧和排放的影响.研究结果表明,由国四标准的97号汽油升级为国五标准的98号汽油,对于压缩比为9.6的GDI发动机来说,燃烧持续期延长,缸压峰值降低,放热率峰值减小.但油品升级有助于降低GDI发动机的排放特性,98号汽油比97号汽油CO排放降低,HC排放降低,NO的排放平均降低4.9％,微粒排放总数量浓度降低.
