Muhtar","doi":"10.1063/1.5138342","DOIUrl":"https://doi.org/10.1063/1.5138342","url":null,"abstract":"The racing quadcopter is one of Unmanned Aerial Vehicle (UAV) type which is for high speed. A frame of the racing quadcopter used carbon fiber material because of its lightness and rigidity; however, it is costly. Because of that, it is essential to consider alternative material, such as polylactic acid (PLA). However, the PLA frame needs some optimization treatments to achieve similar mass and rigidity as the carbon fiber. One of the structural optimization methods that can be used is topology optimization. Although this method will generate some intricate details in geometry, which is difficult for conventional manufacturing, however, with the additive manufacturing technology, the complex geometry is no longer a barrier. The aim of this research is prototyping “the best design” frame using a 3D printer, based on simulation results of stress and total deformation of the racing quadcopter from topology optimization method. The methodology started from the quadcopter modeling, initial simulation with carbon fiber frame and PLA frame using the static structural simulation of finite element software. Continued by topology optimization simulation with some retain masses to obtain some redesign models. The next stage is the final simulation on the redesign models using a similar method as the initial simulation, and then the analysis is established to achieve “the best design”. The last stage is model manufacturing using a 3D printer, model testing, and result evaluation. As a result, “the best design” is achieved from doubling the thickness of PLA frame, establishing redesign of 60% retains mass topology optimization. Then both “the best design” manufacturing and testing are done well, although with some defects.","PeriodicalId":22239,"journal":{"name":"THE 4TH BIOMEDICAL ENGINEERING’S RECENT PROGRESS IN BIOMATERIALS, DRUGS DEVELOPMENT, HEALTH, AND MEDICAL DEVICES: Proceedings of the International Symposium of Biomedical Engineering (ISBE) 2019","volume":"32 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72583717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The drag comprises of pressure and friction or viscous drags. Attaching a disturbance on the bump surface affects significantly on the contribution of pressure and viscous drag. This study is intended to examine the effect of a small wire (tripping wire) attachment on a semi-circular bump surface on the flow characteristics over the semi-circular bump. Special attention of this study is to examine the drag characteristics, pressure distribution, and boundary layer separation point from the bump surface. The study was conducted using experimental and numerical methods. The experiments were conducted in a low-speed wind tunnel at a freestream velocity of 16.5 m/s, corresponding to the flow Reynolds number (Re) of approximately 2.1 × 105. Flat plates with a semi-circular bump with and without wire were attached in the wind tunnel test section used as model tests. The wire is attached at three different angle (θ) locations of the bump surface, namely θ = 30 deg, 40 deg, and 50 deg. The pressure distribution on the plate surface as well as on the bump surface is measured using static pressure taps connected to U-tube manometer. From the pressure distribution, then the pressure drag is obtained from the integration of pressure distribution on the surface. Fluid velocity is measured using a Pitot static tube. Numerical studies was conducted using a commercial software the Fluent. A 2-D, steady flow turbulent model k-ω shear-stress transport (SST) was used in this study. In the numerical simulation, the grid independency test is performed to ensure better results. The results of the study show that the presence of a small wire attached on the bump surface increases to the total drag of the model for all values of θ. Also, the boundary layer separation point on the bump surface for all values of θ occurs at smaller angle comparing to that of the bump without wire. Results from the experimental study compare very well to the results obtained from the numerical simulations with a maximum difference of approximately 5 percent. In this study, the maximum drag occurs for the bump with the tripping wire attached at θ = 50 deg.Flow behavior over a bump attached on a flat plate has significant effect on the total drag.

Herbs treatments use throughout the world for the treatment of neuropathic pain. Jamu Neuropathic Pain Reducer, which consists of aqueous multi herbs extract of nutmeg seed (Myristica fragrans), clove bud (Syzygium aromaticum) and red ginger rhizome (Zingiber officinale var rubrum) was extracted with variation temperature (60, 80, 100 ℃).
