为保证汽车行车安全,前舱盖需满足刚度、模态和行人保护等要求。针对汽车前舱盖的轻量化设计需求,建立了铸铝一体化前舱盖有限元模型,分析了前舱盖的刚度、模态和行人保护性能,构建了RBF-Kriging混合近似模型并联合存档微遗传算法(archive based micro genetic algorithm,AMGA)对前舱盖进行多目标优化。针对多目标优化产生的Pareto解集,提出一种基于模糊层次分析-逼近理想解排序(fuzzy analytic hierarchy process-technique for order preference by similarity to ideal solution,FAHP-TOPSIS)法对Pareto非劣解进行综合性能排名,主客观相结合地选择出最优方案。结果表明,在满足性能要求的前提下,最优一体化前舱盖质量降低了32.14%,轻量化效果显著。

硬质岩层的盾构施工中,全断面硬岩隧道掘进机(tunnel boring machine,TBM)滚刀破岩效率的研究及工程实践广受关注,目前已有的研究成果不能很好地指导TBM掘进参数的设定以及有效提升破岩效率。为解决这一问题,在破岩效率评价标准的基础上,基于比能耗理论对TBM滚刀破岩效率预测模型展开研究。首先,分别推导得到非协同模式和协同模式下的破岩体积计算公式,并对2种模式下的破岩体积进行了计算和分析;其次,结合滚刀法向推力数学模型的推导结果,联立所得破岩体积及滚刀法向推力的相关公式,得到TBM滚刀破岩效率预测模型;最后,依托实际工程的应用及分析对本文所建立的破岩效率预测模型的合理性和实用性进行验证。研究结果表明:相比于其他情况,张拉破坏主导下的滚刀破岩效率更高;所建模型可以有效地应用于TBM掘进现场的破岩效率预测工作中。结合工程案例的有关计算和分析结果,给出了以控制比能耗为主要目标的滚刀贯入度的取值建议,为类似工程建设提供了有效的参考。

Dye desalination is a challenge in the treatment of textile wastewater with high salt concentration. It is imperative to develop salt resistance membrane that is from sustainable materials to effectively treat dye/salt mixtures. And most polymer membrane materials are non-renewable petrochemical *** this paper, a green hydrogel membrane(CMCS-OA-Na Alg) was prepared by non-metallic ions of oxalic acid(OA) cross-linking of two natural macromolecules of sodium alginate(Na Alg) and carboxymethyl chitosan(CMCS). The membrane showed excellent anti-swelling at high salt concentration(swelling rate less than 8.0% in 10.0 wt% Na Cl solution) and good anti-fouling performance. The membrane exhibited a rejection higher than 95.0% for dyes(bright blue, direct black, direct red, and Congo red) and lower than7.0% for Na Cl, which can achieve better dye/Na Cl separation performance. This study provides a promising membrane material for high salt textile wastewater treatment only using water and carbohydrates as raw materials without any organic solvents.
