熱心網(wǎng)友：近二十年來，以振動為主要原因造成的惡性事故相繼發(fā)生，給國家造成了巨大經(jīng)濟損失。而且，振動問題目前仍是新投運大機組不能按期并網(wǎng)、正常投運的主要原因，在機組正常運行期間，振動問題連續(xù)不斷，影響到正常生產(chǎn)，經(jīng)常出現(xiàn)機組減負荷和帶病運行的情況，甚至使機組被迫停機處理，這些事故屢見不鮮。本系統(tǒng)基于LabVIEW虛擬儀器軟件平臺，對汽輪機振動信號進行讀取加窗，并進行譜分析及自相關分析。LabVIEW虛擬儀器就是在以通用計算機為核心的硬件平臺上，由用戶設計定義、具有虛擬前面板、測試功能由測試軟件實現(xiàn)的一種計算機儀器系統(tǒng)。本系統(tǒng)主要完成了對汽輪機振動信號進行讀取，對信號進行矩形窗、漢寧窗、海明窗的加窗選擇，然后分別進行信號的幅值譜、功率譜、相位譜分析及自相關分析，并且具有圖形操作及顯示界面。系統(tǒng)運行結(jié)果證明，本系統(tǒng)能夠完成對信號的讀取，并進行三種窗函數(shù)及各種分析的動態(tài)選擇，并用圖形顯示結(jié)果。Over the last 20 years, mainly due to the vibration caused by the fatal accidents occurred one after another, inflicting huge economic losses. Furthermore, the vibration is still new to large units shipped impossible grid, the normal operation for the main the crew during normal operations, continuous vibration problems affecting the normal production, Units often reduced load and operation of the sick, and even the unit was forced to stand, these incidents not uncommon. The system based on LabVIEW virtual instrument software platform for turbine vibration signal window read, and spectral analysis and correlation analysis. LabVIEW virtual instrument is a common core of computer hardware platform, defined by the user, with virtual front panel, the test function test software from a computer equipment system. The system completed the turbine vibration signal read, the signal rectangular window Hanning, Hamming window window choice, and then the signal amplitude spectrum, power spectrum and phase spectrum analysis and correlation analysis, and operating with graphics and display interface. The result of running the system proved that the system can accomplish the signal read, and three window function and the dynamic analysis of the various options and graphical display with the results.專業(yè)前景 本專業(yè)以工程熱物理學科為主要理論基礎，以內(nèi)燃機和正在發(fā)展中的其它新型動力機械及系統(tǒng)為研究對象，運用工程力學、機械工程學、自動控制、計算機、環(huán)境科學、微電子技術等學科的知識和內(nèi)容，研究如何把燃料的化學能和液體的動能安全、高效、低（或無）污染地轉(zhuǎn)換成動力的基本規(guī)律和過程，研究轉(zhuǎn)換過程中的系統(tǒng)和設備的自動控制技術。隨著常規(guī)能源的日漸短缺，人類環(huán)境保護意識的不斷增強，節(jié)能、高效、降低或消除污染排放物、發(fā)展新能源及其它可再生能源成為本學科的重要任務，在能源、交通運輸、汽車、船舶、電力、航空宇航工程、農(nóng)業(yè)工程和環(huán)境科學等諸多領域獲得越來越廣泛的應用，在國民經(jīng)濟各部門發(fā)揮著越來越重要的作用。 培養(yǎng)目標 本專業(yè)方向培養(yǎng)具備熱能與動力工程專業(yè)方面的基本理論、基本知識和基本技能，能在國民經(jīng)濟各部門從事熱力發(fā)動機和其它新型動力機械及設備的設計、制造、管理、教學和科研等方面的高級工程技術人才。 培養(yǎng)特色 本專業(yè)在加強學生基礎理論和綜合素質(zhì)教育的同時，加強計算機及自動控制技術的應用，強化專業(yè)實踐教學，注重全能訓練，全面提高學生的實踐動手能力和科學研究潛力，使畢業(yè)生具有較強的擇業(yè)競爭能力和較寬的就業(yè)適應能力。 主干課程 機械制圖、機械原理、機械設計、理論力學、材料力學、工程材料、電工技術、電子技術、計算機軟件基礎、液壓技術、液力傳動、內(nèi)燃機構(gòu)造、內(nèi)燃機原理、內(nèi)燃機設計、內(nèi)燃機試驗、發(fā)動機電子技術、工程熱力學、流體力學、傳熱學、自動控制理論、現(xiàn)代測試技術等。 就業(yè)方向 畢業(yè)后可從事能源與動力設備的行政管理、內(nèi)燃機及新型動力設備的開發(fā)研制、內(nèi)燃機排放控制、新能源利用、汽車工業(yè)、兵器工業(yè)、環(huán)保工業(yè)、交通運輸業(yè)、船舶、電力、航空宇航工業(yè)等方面的工作。The prospect of major works of the major hot in physics as the main theoretical basis to the internal combustion engine and the other is the development of new machinery and power systems for the study, the use of engineering mechanics, mechanical engineering, automation, computers, environmental science, microelectronics technology disciplines, such as content knowledge and to study how the chemical energy of fuel and liquid kinetic energy security, high-performance, low (or none) of pollution to the power into the basic law and the process of research in the conversion process of the automatic control systems and equipment technology . With the growing shortage of conventional energy, human the growing awareness of environmental protection, energy saving, high efficiency, reduce or eliminate polluting emissions, the development of new energy and other renewable sources of energy has become an important task for the subjects in the energy, transportation, automotive, ships, electricity, aviation aerospace engineering, agricultural engineering and environmental science in many fields such as access to more and more widely used, the department in the national economy is playing an increasingly important role. Cultivate cultivate goal with the direction of the major thermal power projects with the major aspects of the basic theory, basic knowledge and basic skills, to engage in various departments in the national economy and other heat engines power the new machinery and equipment design, manufacture, management, teaching and scientific research aspects of advanced engineering and technical personnel. Cultivate major characteristics of the students in strengthening the basic theory and the overall quality of education, to strengthen the computer and automatic control technology, and strengthen the teaching of professional practice, pay attention to all the training, students enhance the practice of comprehensive practical ability and scientific research potential, so that graduates have strong competitiveness and a wide choice of employment adaptability. Mechanical Drawing trunk curriculum, mechanical principles, mechanical design, theoretical mechanics, mechanics of materials, engineering materials, electrical technology, electronics technology, computer software foundation, hydraulic technology, hydraulic transmission, the internal combustion engine structure, the principle of internal combustion engines, internal combustion engine design, the internal combustion engine testing, engine electronic technology, engineering thermodynamics, fluid mechanics, heat transfer, automatic control theory, modern test technology. Employment after graduation can be engaged in the direction of energy and power equipment, administration, internal combustion engines and new development of power equipment, internal combustion engine emission control, new energy use, the auto industry, the weapons industry, industrial environmental protection, transport, shipping, electricity, air space industrial job.Motor vehicles are not the only air polluters. Coal and oil, used to heat homes and factories and to generate electricity, contain small amounts of sulfur. When the fuels are burned, sulfur dioxide, a poisonous gas, is produced. It is irritating to the lungs. Some cities have passed laws that allow coal and oil to be burned only if their sulfur content is low. 汽車不是唯一的空氣污染。煤炭和石油，用于家庭取暖和工廠，并產(chǎn)生電力，含有少量的硫。當燃料燃燒，二氧化硫，一種有毒氣體，就產(chǎn)生了。它是刺激到肺部。一些城市已通過法律，允許煤炭和石油只有在其被燒毀硫含量低。Most electricity is generated by steam turbines. about half of the sulfur dioxide in the air comes from burning fuel to make steam. Nuclear power plants do not burn fuel, so there is no air pollution of the ordinary kind. But the radioactive materials in these plants could present a danger in an accident. Also, there is a problem in disposing of the radioactive wastes in a way that will not endanger the environment. 大部分電力是由蒸汽渦輪機。關于空氣中的二氧化硫，使蒸汽一半來自燃料燃燒。核電廠不燒燃料，所以不存在的那種普通的空氣污染。但是，在這些植物的放射性物質(zhì)可能會提出一個意外的危險。此外，還有一個在放射性廢物處置的方式，不會危害環(huán)境的問題。Another type of pollution, called thermal (heat) pollution, is caused by both the fuel-burning and nuclear plants. Both need huge amounts of cold water, which is warmed as it cools the steam. When it is returned to the river, the warm water may stimulate the growth of weeds. It may also kill fish and their eggs, or interfere with their growth.另一種污染類型，稱為熱（熱）污染，是造成雙方的燃料燃燒和核電廠。雙方都需要的冷水，這是溫暖，因為它大量的蒸汽冷卻。當返回到河邊，溫暖的水會刺激雜草生長。它也可以殺死魚，它們的卵，或干擾他們的成長。Physicists are studying new ways of generating electricity that may be less damaging to the environment. In the meantime, many power plants are being modernized to give off less polluting material. Also, engineers try to design and locate new power plants to do minimum damage to the environment.物理學家們正在研究發(fā)電對環(huán)境損害較小的新方法。與此同時，許多發(fā)電廠也在實現(xiàn)現(xiàn)代化以減少污染物質(zhì)。此外，工程師們嘗試設計并找到對環(huán)境的損害最小的新的發(fā)電廠。Thermal energy and power engineeringThis program is to cultivate both master thermal energy and power engineering professional basic theoretical knowledge, computing skills, but also the ability in various forms of generating power plant, refrigeration and air conditioning, new energy related fields in need of economic management knowledge and ability, can be engaged in the electric power industry related to areas of science and technology application, research, development and management of a senior talents.
