【摘要】：發(fā)動(dòng)機(jī)是飛機(jī)上的一個(gè)十分重要的組成部分,它性能的好壞,直接決定飛機(jī)能否安全飛行。所以,對(duì)發(fā)動(dòng)機(jī)進(jìn)行安裝前檢查,定期保養(yǎng),故障診斷等性能檢測(cè)工作是非常重要的,它能夠確保其性能良好、工作可靠,對(duì)軍隊(duì)?wèi)?zhàn)斗力的提高具有很大作用。飛機(jī)發(fā)動(dòng)機(jī)地面試車系統(tǒng)采用計(jì)算機(jī)控制技術(shù)和數(shù)據(jù)采集技術(shù),實(shí)現(xiàn)了對(duì)發(fā)動(dòng)機(jī)各個(gè)性能參數(shù)的測(cè)試,降低了對(duì)操作人員的要求,提高工作效率,確保發(fā)動(dòng)機(jī)使用可靠性。該系統(tǒng)主要由發(fā)動(dòng)機(jī)凸輪(CAM)信號(hào)測(cè)試模塊、發(fā)動(dòng)機(jī)轉(zhuǎn)速測(cè)試模塊、發(fā)動(dòng)機(jī)壓力信號(hào)測(cè)試模塊、發(fā)動(dòng)機(jī)溫度信號(hào)測(cè)試模塊幾部分組成。論文重點(diǎn)給出了系統(tǒng)的設(shè)計(jì)思路、技術(shù)方案的選擇、系統(tǒng)的軟硬件設(shè)計(jì)和系統(tǒng)的關(guān)鍵技術(shù)幾個(gè)主要部分。硬件系統(tǒng)的設(shè)計(jì)是以PLC作為控制核心,選用壓力變送器和溫度變送器等敏感元件來(lái)采集發(fā)動(dòng)機(jī)的壓力與溫度信號(hào),發(fā)動(dòng)機(jī)凸輪信號(hào)等可直接由PLC采集。軟件系統(tǒng)方面,上位機(jī)采用軍用筆記本電腦,組態(tài)軟件Delphi 2010作為開發(fā)環(huán)境,設(shè)計(jì)了簡(jiǎn)單、易操作的上位機(jī)管理系統(tǒng),實(shí)現(xiàn)了對(duì)發(fā)動(dòng)機(jī)壓力、溫度、凸輪等信號(hào)的實(shí)時(shí)監(jiān)控。另外,針對(duì)測(cè)試過(guò)程中發(fā)動(dòng)機(jī)故障不好判斷的現(xiàn)象,提出了一種基于模糊神經(jīng)網(wǎng)絡(luò)的發(fā)動(dòng)機(jī)故障智能判斷的方法,此方法很好的解決了發(fā)動(dòng)機(jī)狀態(tài)判斷的問(wèn)題,結(jié)果令人滿意。目前,本課題設(shè)計(jì)的發(fā)動(dòng)機(jī)地面試車系統(tǒng)已經(jīng)投入使用,經(jīng)過(guò)實(shí)踐證明,該系統(tǒng)運(yùn)行良好,能充分滿足部隊(duì)的需要。
[Abstract]:The engine is a very important part of the aircraft, its performance directly determines whether the aircraft flight safety. So, the engine was installed before the inspection, regular maintenance, fault diagnosis performance test is very important, it can ensure the good, the work is reliable, has a great effect on the army enhance combat capability. The aircraft engine ground test system adopts computer control and data acquisition technology, the realization of various engine performance parameter testing, reducing the operating personnel requirements, improve work efficiency, ensure the reliability of the engine. The system is mainly composed of engine cam (CAM) engine speed signal test module, test module engine pressure, engine temperature signal test module, signal test module composed of several parts. The paper gives the system design ideas, technical scheme The choice of several key technologies of hardware and software design of system and the design of hardware. The system uses PLC as the control core, the pressure transmitter and temperature transmitter and other sensitive components to collect the temperature and pressure signal of the engine, the engine cam signal can be directly collected by PLC. The software system, using PC protection notebook computer, configuration software Delphi 2010 as the development environment, design a simple, easy-to-use PC management system, realized the temperature of engine pressure, real-time monitoring of cam signal. In addition, the testing process of engine fault bad judgment phenomenon, put forward a method of engine fault intelligent fuzzy judgment based on Neural Network, this method solves the problem of engine condition judgment, with satisfactory results. At present, the design of the engine to the interview The car system has been put into use. It has been proved by practice that the system runs well and can fully meet the needs of the army.
