提出了一种在满足动力性需求并且以氢燃料电池堆作为主要能源的前提下,能有效延长电堆使用寿命的能量管理策略。提出将需求功率SG滤波后再进行规则控制的能量管理策略,将多种循环工况的结果进行手动优化后作为训练数据集,设计三输入一输出的自适应神经模糊推理系统控制器,根据其输出结果再进行一次滤波最终形成基于自适应神经模糊推理系统优化的能量管理策略。使用CLTC-P循环工况对能量管理策略进行仿真验证,结果表明,基于自适应神经模糊推理系统优化的能量管理策略能有效延长氢燃料电池剩余使用寿命,相比滤波加规则策略剩余使用寿命增加了33%,并能保持动力电池SOC处于适宜水平。

以汽车控制臂焊接构件作为研究对象,利用SYSWELD软件对控制臂构件的焊接热输入和焊接顺序进行优化。结果表明:当焊接热输入偏小时(2 015~2 266 J/cm),控制臂上下片之间的角焊缝焊根位置会出现未焊透缺陷;当焊接热输入适中时(2 527~2 701 J/cm),角焊缝能获得较好的焊缝熔宽和熔深。此外,对比分析不同焊接顺序下控制臂的残余应力和变形,发现采用先中间后两边((1)(4)(3)(5)(6)(2)(7)(8))的焊接顺序有利于降低控制臂整体的残余应力峰值;采用其它的焊接顺序时,控制臂整体的残余应力峰值较高,焊接变形也较大。试验与仿真结果对比表明,仿真结果的准确性较高,利用有限元仿真能优化汽车控制臂的焊接工艺,提高控制臂产品的焊接质量。
