基于对已有的几种灰数灰度定义的讨论,建立了灰数灰度定义的公理系统;以灰数灰度定义公理为准绳,由灰数产生的背景或论域及灰数取数域的测度构造出一种新的灰数灰度定义式。新定义克服了原有定义中存在的问题,较为科学地描述了灰数的不确定程度。

本文提出了一种具有环形接收区域的微波无线能量传输发射天线口径场分布设计方法。该设计的目标是最大化辐射到环形接收区域上的微波功率与总传输功率的比值。通过将口径场幅度分布表示为一组特殊级数的求和,可将该最优设计问题简化为寻找两个实二次型的最大比值。基于矩阵论,可通过确定最大特征值及其对应的特征向量来解决该优化问题。为满足安全要求,将接收区域外的峰值辐射电平视为额外约束。为解决该约束优化问题,提出了将灰狼优化算法和Nelder-Mead单纯形法结合的混合优化方法。为证明所提方法的有效性,首先,对连续口径场分布进行数值仿真实验。然后,使用离散阵列天线来验证优化结果的正确性,其中单元假设为各向同性的点源。最后,采用微带贴片阵列来进一步验证所提出方法的有效性。

This paper investigates optimization problem of the cutting parameters in high-speed milling on NAK80 mold steel. An experiment based on the technology of Taguchi is performed. The objective is to establish a correlation among spindle speed, feed per tooth and depth of cut to the three directions of cutting force in the milling process. In this study, the optimum cutting parameters are obtained by the grey relational analysis. Moreover, the principal component analysis is applied to evaluate the weights so that their relative significance can be described properly and objectively. The results of experiments show that grey relational analysis coupled with principal component analysis can effectively acquire the optimal combination of cutting parameters and the proposed approach can be a useful tool to reduce the cutting force.

现实生活中遇到的许多问题都具有不确定性,使得在对系统进行决策评估时,指标值难以精确化。在此情形下,人们常常对指标值给出一个区间,到目前为止, 尚未有人研究区间数灰靶决策。首先定义了区间数、m维区间数的距离及其距离性质,并证明了当区间数为实数时,区间数距离就是实数距离的推广;提出了区间数规范化方法,在此基础上, 建立了基于区间数的灰靶决策模型,从而把灰靶决策模型由实数序列拓展到区间数序列,使灰靶决策理论得到发展,同时为扩大灰靶决策的应用领域提供了理论根据。最后以实例验证了该模型的有效性与实用性。

Through a pin-on-disc type wear setup, the dry sliding wear behavior of SiC-reinforced aluminum composites produced using the molten metal mixing method was investigated in this paper. Dry sliding wear tests were carried on SiC-reinforced metal matrix composites (MMCs) and its matrix alloy sliding against a steel counter face. Different contact stresses, reinforcement percentages, sliding distances, and sliding velocities were selected as the control variables, and the responses were selected as the wear volume loss (WVL) and coefficient of friction (COF) to evaluate the dry sliding performance. An L25 orthogonal array was employed for the experimental design. Initially, the optimization of the dry sliding performance of the SiC-reinforced MMCs was performed using grey relational analysis (GRA). Based on the GRA, the optimum level parameters for overall grey relational grade in terms of WVL and COF were identified. Analysis of variance was performed to determine the effect of individual factors on the overall grey relational grade. The results indicated that the sliding velocity was the most effective factor among the control parameters on dry sliding wear, followed by the reinforcement percentage, sliding distance, and contact stress. Finally, the wear surface morphology and wear mechanism of the composites were investigated through scanning electron microscopy.

针对目前区间灰数的表征和运算过程中存在着较为严重的问题,即:运算结果对灰数的灰度进行不必要的放大,造成信息的严重失真,笔者定义了标准区间灰数与第一和第二标准区间灰数的概念,分析了第一和第二标准区间灰数之间的关系,进一步设计了普通区间灰数与标准区间灰数之间的转换规则,提供了标准区间灰数之间的比较与运算法则,较好地解决了区间灰数之间的大小比较与运算问题。最后,将这一研究成果应用于基于区间数的GM (1, 1)模型预测问题,取得了良好的效果。
