The reliability-based design optimization, the reliability sensitivity analysis and robust design method are employed to present a practical and effective approach for reliability-based robust design optimization of vehicle components. A procedure for reliability-based robust design optimization of vehicle components is proposed. Application of the method is illustrated by reliability-based robust design optimization of axle and spring. Numerical results have shown that the proposed method can be trusted to perform reliability-based robust design optimization of vehicle components.

陶瓷喷墨打印增材制造技术 Review

陶瓷喷墨打印是一种基于微滴累加的成形技术,典型的微滴体积为10~100 pL。实现微滴累加成形的关键是开发稳定的陶瓷墨水,合适的墨水需要满足由雷诺数和韦伯数定义的流变特性参数空间。在微滴累加成形过程中,微滴首先与成形面碰撞变形并消耗动能,然后在毛细管力作用下铺展并达到平衡状态。已经可以确定的是打印过程中微滴相互作用并形成一维线性特征的机理,但是对二维和三维结构成形机理的认识还处于较低水平,成形二维面的稳定性低于成形一维线性结构。多数情况下,墨水通过蒸发固化,微滴碰撞基体所产生的“咖啡环”缺陷需要通过固化工艺加以控制。已经有大量文献报道了使用喷墨打印技术成形各种类型小型陶瓷零件的成功案例。作为一种未来的制造技术,陶瓷喷墨打印技术有广阔的应用前景。本综述的目的是探索陶瓷喷墨打印技术未来潜在的研究领域,加强对这种制造方法的理解。

The reliability-based optimization, the reliability-based sensitivity analysis and robust design method are employed to propose an effective approach for reliability-based robust design optimization of vehicle components in Part I. Applications of the method are further discussed for reliability-based robust optimization of vehicle components in this paper. Examples of axles,torsion bar, coil and composite springs are illustrated for numerical investigations. Results have shown the proposed method is an efficient method for reliability-based robust design optimization of vehicle components.

植物油料是植物油脂与植物蛋白的主要来源。油脂中所含的某些脂肪酸及某种结构的甘油酯具有特殊的生理功能,近几年来,这方面的研究开发取得了重要进展。国内外的油脂工业主要是利用油料生产各种食用油脂,其次是获取植物蛋白制品。实际上,在油脂精炼及植物蛋白制取过程中产生的许多所谓“废料”,长期以来未得到充分利用。近些年发现,在“废料”中很多伴随油脂的类脂物及伴随植物蛋白的植物化学品,具有独特的生理效能,因而这些高附加值的功能性成分的开发利用受到高度重视。由于油料中的功能性成分的特殊性,现有的油料加工工艺与装备不能适应其分离提取的要求,由此推动着油脂工程技术的发展和生物技术在功能性结构脂开发上的应用。

Concrete members historically have used either pre-stressed steel or steel bars. In recent years there has been an increased interest in the use of fiber reinforced polymer (FRP) materials. However, the flexure behavior of a hybrid system reinforced by the combination of pre-stressed steel and glass fiber reinforced (GFRP) is still relatively unknown. The purpose of this work is to study this. Two slabs of 100 and 150-millimeter thickness, with a span of 2.1 m reinforced with both pre-stressing steel and GFRP were constructed and tested to failure using ACI 318-11 and ACI 440.1R-15. The concrete had strength of 31 MPa and the slabs were respectively reinforced with 5#4 bars and 3#5 bars. Each slab had 37.41 mm2 prestressing wire with a failure stress of 1722.5 MPa. The experimental flexural strength and deflection of slabs were compared with their respective sizes theoretical slabs. The theoretical slabs were either reinforced with pre-stressed steel or GFRP rebars, or a hybrid system. It was found that the hybrid system produces better results.

Carbon fibre reinforced carbon (CFC) materials show a high potential for usage in furnaces as sample carriers for example, which is due to their excellent thermal stability compared to steel carriers. Only their tendency to react with different metals at high temperatures by C-diffusion is a disadvantage, which can be solved by application of diffusion barriers. In order to enable the utilization of CFC-carriers for e.g. brazing furnaces, within the frame of this study thermally sprayed diffusion barrier coatings were developed. Coatings of mullite and ZrO2-7%βY2O3 (YSZ) were prepared by air plasma spraying (APS). The coatings were investigated in terms of their microstructure and thermal shock behaviour. In order to prove the suitability of the coatings for the application in brazing furnaces, the wettability of the coating surfaces by a Ni-based brazing alloy was investigated. The results showed that both mullite and YSZ could be deposited on CFC substrates with a bond coat of W or SiC. Both coatings exhibited good thermal shock behaviour and an excellent non-wetting behaviour against the used Ni-based braze alloy.
