Acoustical Analysis and Drilling Process Optimization of Camellia Sinensis / Ananas Comosus / GFRP / Epoxy Composites by TOPSIS for Indoor Applications
.
Camellia Sinensis/Ananas Comosus/GFRP/Epoxy Polymer composites are widely accepted to be a better material for indoor sound damping. It has a series of challenges, like force cuts on the drilling of these composites. The focus is to drill on hybrid laminates by changing the cutting conditions like the speed and feed and the selection of optimum machining process parameters. Nine experimental cycles have been performed, and five various attributes were analyzed, for example, torque, tangential force, thrust force, and also the factor of delamination (Enter & Exit). This study shows a sequential parameter selection for the drilling machining process. Using Multi-attribute optimization, order preference and optimum drilling machining process parameters are selected by the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). From the TOPSIS analysis, the best suitable optimum drilling conditions for hybrid laminates are chosen as 600 rpm and 0.02 m/min for cutting speed and feed rate, respectively.
摘要
Camellia Sinensis /Ananas-Comosus/GFRP/环氧树脂复合材料是一种较好的室内消声材料。它有一系列的挑战，比如在这些复合材料的钻孔上的力切割. 重点是通过改变切削速度、进给量等切削条件，选择最佳的加工工艺参数，在复合材料层合板上钻孔. 已经进行了九个实验循环，并分析了5种不同的属性，例如扭矩、切向力、推力以及分层（进入和退出）因素. 本文提出了一种顺序参数选择的钻削加工方法. 采用多属性优化方法，通过与理想解的相似性排序技术（TOPSIS），选择了顺序优选和最优钻削加工工艺参数. 通过TOPSIS分析，确定了复合材料层合板的最佳钻削条件为：切削速度为600rpm，进给速度为0.02m/min.

I have a laundry list of conditions, both physical and mental. I am looking at a few different types of CBD, namely vape juices and flowers. I am looking for strains that help with anxiety, depression, insomnia, PTSD, mood swings, and nerve and joint pain. I take medication for all of these things, but these conditions still plague my life. Are there any specific strains or flowers I should be looking at?
My wife uses the CBD flower and I was thinking about making her flower into gummies. A friend of her gave her 2 ounces of flower, but that’s way too much for her to use before it goes bad. I tried googling some stuff but it’s all pretty confusing and it was like factory production of CBD. Any info this group may have will be very helpful!
