Search Symbol (Half-width)	Description of Search Symbols
Space	"AND" indicates the intertwining of key terms used in a search
Double Quotation Marks ("") ( " " )	Double quotation marks indicate the beginning and end of a phrase, and the search will only include terms that appear in the same order of those within the quotations. Example: "image process" ： " image process "
?	Indicates a variable letter. Entering two ? will indicate two variable letters, and so on. Example: "Appl?", search results will yield apple, apply… e , appl y … ( (often used to English word searches) )
*	Indicates an unlimited number of variable letters to follow, from 1~n. Example: Enter "appl*", search results will yield apple, apples, apply, applied, application…(often used in English word searches) e , appl es , appl y , appl ied , appl ication … ( (often used to English word searches) )
AND、OR、NOT	Boolean logic combinations of key words is a skill used to expand or refine search parameters. (1) AND (1) AND: Refines search parameters (2) OR (2) OR: Expands search parameters (3) NOT: Excludes irrelevant parameters

DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

The dissertation was developed to design and authenticate the server chassis by finite element simulation and actual measurement.Observe the server chassis will deform over 0.4mm to interfere with assembly or not after putting in the hard disks. Refer to the relationship of the constructions in the server chassis and the overall structural strength to set up a process of server chassis parameter design.By Taguchi experimental design, adopt the server chassis material thickness, punch type, fan wall height and HDD size as controllable factor. Use finite element simulation ABAQUS as a substitute for experiment to analyze server chassis orthogonal arrays.By orthogonal arrays to screen the best parametric combination, then use Taguchi experimental design to forecast the S / N ratio of the prediction confirmation, analyzing the prediction confirmation by finite element simulation and observe the amount of deformation. Convert the amount of deformation to the S / N ratio to verify with the prediction of Taguchi experimental design.
After making and installing the server chassis, using Magnetic Block, link bracket and marble platform to make the mensuration base.Use digital percentile scale to measure the amount of deformation and calculate the S/N ratio, then verify with the prediction of Taguchi experimental design. The amount of deformation is 0.143mm, and the average error percentage is 8.01%. Because the server chassis were out of shape in fabrication, the error percentage is higher. However, the amount of deformation server chassis are not over 0.4mm, so it wouldn’t interfere with fabrication.
According to ISTA conducted server chassis fell off the analysis and testing. Using Ls-Dyna as Solver and help the HyperWorks operate the pre and post processing. We get a result that the Max stress is 165MPa and yield strength of steel material is 320MPa after we finishing the fell off experiment. In terms of the coefficient of safety is 1.93. So it is predictable the servo chassis could pass the fell off tests. In addition there was no physical damage and whole functions are all normal after entire check.
