提出了分析调水工程渠道沿程糙率的系统辨识新方法。依据水力学原理,建立了渠道沿程糙率与粗糙高度ks和水力半径R的函数关系,然后通过数学变换提出了适合最小二乘法进行系统辨识的线性模型。并以南水北调中线工程原型观测资料为基础,考虑渠道断面形状、底坡、渠长变化的影响,应用系统辨识的方法消除水力测量随机误差的干扰,得到了通用的渠道沿程糙率计算公式。

Abrasive waterjet cutting is a novel machining process capable of processing wide range of hard-to-cut materials. Surface roughness of machined parts is one of the major machining characteristics that play an important role in determining the quality of engineering components. This paper shows the influence of process parameters on surface roughness (Ra) which is an important cutting performance measure in abrasive waterjet cutting of aluminium. Taguchi’s design of experiments was carried out in order to collect surface roughness values. Experiments were conducted in varying water pressure, nozzle traverse speed, abrasive mass flow rate and standoff distance for cutting aluminium using abrasive waterjet cutting process. The effects of these parameters on surface roughness have been studied based on the experimental results.

结构性干预包括修复和(或)改善结构性能。除了混凝土和钢材这两种典型的混凝土结构材料外,各种纤维增强复合材料(FRP),混合纤维、聚合物和黏合剂的黏结材料也常被用于结构性干预。为了预测结构性能,有必要开发一种不仅适用于钢材,而且适用于其他材料的通用方法。这种通用模型可以提供有关改善结构性能所需的力学性能的信息。外部黏结是一种典型的结构干预方案,在新结构中没有得到应用。为了在基体混凝土和外部黏结材料的接合点上获得更好的黏结强度,我们有必要阐明材料的性能和结构细节。本文介绍基体混凝土的力学性能和相关干预材料用于以下目的:①获得更高的抗剪强度和减少构件在结构性干预后的极限变形;②使外部黏结获得更高的黏结强度。本文得出的结论是,在有结构干预的结构中,为了提高结构的力学性能,干预材料的一些力学性能和结构细节是新的,且不同于没有干预的结构。例如,在无结构性干预的结构中,高强度和高刚度是材料的重要性能,而高断裂应力和低刚度是结构干预材料的重要性能。

The Inconel 718 alloy is widely used in the aerospace and power industries. The machining-induced surface integrity and fatigue life of this material are important factors for consideration due to high reliability and safety requirements. In this work, the milling of Inconel 718 was conducted at different cutting speeds and feed rates. Surface integrity and fatigue life were measured directly. The effects of cutting speed and feed rate on surface integrity and their further influences on fatigue life were analyzed. Within the chosen parameter range, the cutting speed barely affected the surface roughness, whereas the feed rate increased the surface roughness through the ideal residual height. The surface hardness increased as the cutting speed and feed rate increased. Tensile residual stress was observed on the machined surface, which showed improvement with the increasing feed rate. The cutting speed was not an influencing factor on fatigue life, but the feed rate affected fatigue life through the surface roughness. The high surface roughness resulting from the high feed rate could result in a high stress concentration factor and lead to a low fatigue life.
关键词: roughness hardness residual stress microstructure fatigue life
