In order to improve the accuracy and efficiency of the environmental protection evaluation results of building materials, a new environmental protection evaluation method of inorganic non-metallic building materials based on principal component analysis was proposed. Firstly, knowledge atlas and collaborative filtering algorithm are used to mine evaluation indicators. Then, the evaluation index system is constructed, and the judgment matrix is established to calculate and sort the weight of the evaluation index. Finally, the principal component analysis method is introduced to evaluate the environmental protection performance, and the original evaluation index is standardised to obtain the comprehensive score of the environmental protection performance of building materials, to realise the environmental protection performance evaluation. The experimental results show that the evaluation accuracy of the proposed method is high and the time consumption is short, indicating that the evaluation results are reliable.
为了提高建筑材料环保评价结果的准确性和效率,提出了一种基于主成分分析的无机非金属建筑材料环保评价新方法。首先,利用知识图谱和协同过滤算法挖掘评价指标;然后,构建评价指标体系,建立判断矩阵,对评价指标的权重进行计算和排序。最后,引入主成分分析法对建筑材料的环保性能进行评价,并对原有的评价指标进行标准化,得到建筑材料的环保性能综合得分,实现对建筑材料的环保性能评价。实验结果表明,该方法的评估精度高,耗时短,表明评估结果可靠。

The different electroplastic effects of cutting directions during the turning process of Ti-6Al-4V titanium alloy Ti-6Al-4V钛合金车削过程中切削方向的不同电塑性效应

Electroplastic assisted process is a new machining technology, which can reduce the tensile strength and spring back of materials and increase the formability and quality of the workpiece. Currently, this technology has been successfully applied in electroplastic-assisted rolling, drawing, and turning. However, most research in electroplastic-assisted turning is focused on reducing the cutting force and energy consumption and improving surface quality. The differences in cutting forces reduce caused by electroplastic in different directions have not been reported. In this paper, we compare the decrement of cutting forces in different directions during the electroplastic-assisted turning of titanium alloy (TC4). It is found that there is no obvious force reduction in the tangential direction compared to that in the feed direction. The possible explanation is that the electroplastic effect does not work in reducing compressive stress. This was validated by electroplastic-assisted cut-off turning and electroplastic-assisted compressing experiments. This work provides a deep insight into understanding the electroplastic mechanism and offers a guide for the application of electroplastic-assisted forming.
电塑性辅助加工是一种新的加工技术,它可以降低材料的抗拉强度和回弹,提高工件的成形性和质量。目前,该技术已成功应用于电塑辅助轧制、拉伸和车削。然而,电塑辅助车削的研究大多集中在减小切削力和能量消耗以及提高表面质量上。不同方向的电塑性引起的切削力降低差异尚未见报道。本文比较了钛合金(TC4)电塑性辅助车削过程中不同方向切削力的减量。与进给方向相比,切向力没有明显的减小。可能的解释是,电塑性效应在降低压应力方面不起作用。通过电塑性辅助切断车削和电塑性辅助压缩实验验证了这一点。这项工作为了解电塑性机理提供了深入的见解,并为电塑性辅助成形的应用提供了指导。

This paper summarises a comprehensive and systematic review of 29 quantitative studies from peer-reviewed journals published in ranked publications between 1992 to 2015 on the determinants of innovation cooperation for manufacturing SMEs. Applying a documented methodology, it crystallises acquired knowledge by identifying, synthesising and discussing 220 unique determinants stemming from a vast and heterogeneous body of literature. The article introduces an analytical framework integrating different perspectives to approach this concept presenting a holistic and integrated view of the topic. It provides a typology that sorts the determinants into six categories: 1) environmental characteristics; 2) industrial characteristics; 3) organisational characteristics; 4) individual characteristics; 5) partnership characteristics; 6) project characteristics. This systematic review also identifies current gaps in the literature. The provided research perspectives will allow researchers and policymakers to better foster innovation and guide researchers addressing this phenomenon in the future. It clearly lays a foundation for future research on the topic, organising and building upon the literature that has been published so far.
