本文选取甘蔗渣在270℃条件下进行烘焙预处理。通过沉降炉上的燃烧实验,研究了烘焙对甘蔗渣燃烧PM_(10)以及沾污生成的影响。结果表明,烘焙后甘蔗渣燃烧PM_1生成量明显减少,这主要是因为烘焙降低了甘蔗渣中Cl、S的含量。同时,烘焙甘蔗渣燃烧PM_(1-10)生成量降低,这主要是由于烘焙促进了燃烧中灰颗粒间的聚结,进而使PM_(1-10)迁移转化至PM_(10+)。另一方面,烘焙甘蔗渣燃烧沾污内层沉积率减少了约45%,这与烘焙甘蔗渣燃烧过程中碱金属盐以及PM_(1)的生成的减少有关。

以带附加气室容积可调空气悬架的整车为研究对象,首先建立附加气室容积可调空气弹簧模型,并将该模型以弹簧力形式引入整车,然后设计以平顺性指标为主导地位的综合目标函数及约束条件。采用改进遗传算法对该目标函数进行逐段优化,同时得到不同工况下前悬架和后悬架模糊控制器的最优输出数据。最后将该输出数据作为导师信号供神经网络学习,从而建立整车半主动空气悬架的T-S型神经模糊控制器。仿真结果表明:在不同行驶工况下,相比被动空气悬架,采用神经模糊控制的半主动空气悬架的行驶平顺性显著提高,且满载时的改善效果优于空载。
