工程現(xiàn)場惡劣的工作環(huán)境（潮濕、粉塵、高溫、電磁干擾等）對信息采集終端的結(jié)構(gòu)提出了嚴格的要求。在終端結(jié)構(gòu)設(shè)計時，不僅要滿足強度、剛度要求，還要滿足終端在現(xiàn)場使用的可靠性要求。
根據(jù)機械結(jié)構(gòu)設(shè)計原則，分析現(xiàn)有終端的組成并充分考慮終端的工作環(huán)境，提出了終端結(jié)構(gòu)設(shè)計思路和設(shè)計流程。根據(jù)終端的應(yīng)用要求提出了總體的設(shè)計方案，將其劃分為機箱外殼、安裝板系列和電池盒系列三部分。
在此基礎(chǔ)上，結(jié)合自下而上和自頂向下的設(shè)計方法，應(yīng)用三維設(shè)計軟件SolidWorks完成終端機械零部件設(shè)計，并利用COSMOSWorks對主安裝板和上箱分別進行熱分析和靜力學分析，保證使用的安全性。在設(shè)計的過程中，特別考慮可靠性如何在在結(jié)構(gòu)設(shè)計中得到保證，主要進行熱設(shè)計、電磁兼容設(shè)計、防潮和防塵設(shè)計。
應(yīng)用虛擬裝配技術(shù)，驗證所設(shè)計零件的可裝配性。經(jīng)過反復的裝配試驗，消除零件之間的干涉，確立零部件的裝配序列和裝配路徑。虛擬裝配結(jié)果表明論文所述的結(jié)構(gòu)設(shè)計方案可行，具有實用價值。

Abominable working conditions of engineering scenes (humidity, bug dust, high temperature, electromagnetic interference etc.) put forward serious requests to the structure of information acquisition terminal, when designing terminal structure, it needs to satisfy not only the requests of intensity and rigidity, but also requests of reliability which used in the engineering sites.
Based on the mechanism design criterion, by analyzed the existing terminal's composition and considered the terminal’s working environments, this article proposed design mentality and design cycle for the terminal structure. And proposed the overall design scheme according to the terminal application requirements, which divided the structure into three parts, including chassis crust, mounting card and battery cases.
Based on this, combining with UP-to-Down and Down-to-TOP designing methods, designed all mechanical parts of terminal model with the application of SolidWorks (a three-dimensional design software). and carried out thermal analysis and statics analysis for main mounting cards and top boxes via using COSMOSWorks to make sure that they would be working safely. In the designing process, especially considered how to ensure reliability in the structure design. And mainly carried out thermal design, electromagnetic compatibility design, moisture-proof and dust-proof design.
Then checked the assembling capacity of designed parts via using virtual assembly technology. After repeat assembly experiment, the interference among parts was dispelled and the sequence and path of assembly were established. The results of virtual assembly indicate that the scheme of structure design in this paper is feasible and it has practical value.
