【摘要】：航空發(fā)動機是飛機的心臟,是飛機性能的決定因素之一。作為國內主要發(fā)動機科研及生產基地,肩負著國家重點型號發(fā)動機的生產重任。而發(fā)動機臺架試車是發(fā)動機出廠裝機的最后一道工序,是保證發(fā)動機能夠高效安全工作在飛機上的重要環(huán)節(jié)。而軍方的軍檢驗收試車是驗收/交付試車中非常重要的部分,驗收代表要對發(fā)動機的技術狀態(tài)、排除故障情況、發(fā)動機性能參數等進行軍檢驗收試車。軍檢驗收試車過程是復核性的試車,其特點是,可在集中的時段內,對提交前的發(fā)動機的試車結果進行較全面地檢查。這種軍檢方式,長期以來一直被國內發(fā)動機行業(yè)的軍方驗收沿用,對發(fā)動機出廠前質量控制起重要作用。但是,隨著國內軍用發(fā)動機及試驗設備技術水平的現代化,使用100%復核驗收試車方式的軍檢驗收方法已顯示出其不足。為了使試車臺能夠更加準確的給出試車結論、有效的完成發(fā)動機試車任務,本文設計了一個具有數據采集和網絡通訊功能并能實時模擬顯示發(fā)動機試車過程的軟件系統(tǒng)。該系統(tǒng)基于Spring、Struts、Ibatis輕量級J2EE體系架構,在前端展現上采用AJAX和FLASH技術。本文運用軟件工程設計理念和方法,給出了系統(tǒng)的需求分析、設計和實現,完成了試車過程管理,標準頻譜-頻譜轉換和人機對話等模塊功能,并對關鍵功能模塊進行了測試。本系統(tǒng)通過對發(fā)動機檢驗試車的實時監(jiān)控,對發(fā)動機試車數據進行采集和整合并通過局域網傳輸到系統(tǒng)后臺,最后給出發(fā)動機試車的最終結果,能夠有效的提高航空發(fā)動機試車的準確性,同時能夠降低人工參與度,從而能夠實現驗收試車從簡單的復核方式向全過程質量控制轉變。目前,該系統(tǒng)已經投入使用,實際運行效果可以高效,穩(wěn)定的對發(fā)動機試車進行全程監(jiān)控。大大的降低了試車成本,提高了試車效率、改善了試車流程、優(yōu)化了試車工藝。
[Abstract]:Aeroengine is the heart of aircraft and one of the determinants of aircraft performance. As the main engine research and production base in China, it shoulders the important task of national key engine production. The engine bench test is the last process of engine installation, and it is an important link to ensure the engine can work efficiently and safely on the aircraft. The military inspection and acceptance test is a very important part of the acceptance / delivery test. The acceptance representative should carry out the military inspection and acceptance test on the technical status of the engine, troubleshooting, engine performance parameters, and so on. The process of military inspection and acceptance test is a rechecking test, and its characteristic is that the test results of engine before submission can be checked more comprehensively in the centralized period of time. This kind of military inspection method has been used by the domestic engine industry for a long time, which plays an important role in the quality control before the engine leaves the factory. However, with the modernization of the technical level of domestic military engines and test equipment, the military inspection and acceptance method using 100% recheck and acceptance test method has shown its shortcomings. In order to make the test platform more accurate to give the test results, effectively complete the engine test task, this paper designed a software system with the functions of data acquisition and network communication and real-time simulation to display the engine test process. The system is based on Spring Struts / Ibatis lightweight J2EE architecture and uses AJAX and FLASH technology in front end rendering. In this paper, the requirements analysis, design and implementation of the system are given by using the software engineering design concept and method. The functions of the modules such as the process management of the test run, the standard spectrum conversion and the man-machine dialogue are completed, and the key function modules are tested. The system collects and integrates the engine test data through the real-time monitoring of engine testing and testing, and transmits it to the background of the system through LAN. Finally, the final results of engine test are given. It can effectively improve the accuracy of the aero-engine test and reduce the degree of manual participation, so that the acceptance test can change from a simple way of checking to the whole process of quality control. At present, the system has been put into use, the actual operation effect can be efficient and stable to monitor the whole process of engine test. It greatly reduces the test cost, improves the efficiency, improves the test flow and optimizes the test process.
