【摘要】：目前由于客、貨運(yùn)運(yùn)輸需求的多樣化造成車輛種類繁多,車輛的結(jié)構(gòu)與使用條件的逐漸復(fù)雜化,商用車的使用性能要求也逐步提升,對車輛相關(guān)性能的檢測要求也受到重視。對于車輛平順性與操穩(wěn)性的研究,主要分為通過計算機(jī)模擬性試驗與道路實車試驗兩種。汽車試驗場將車輛使用過程中的實際道路濃縮,設(shè)置了各種特殊路面,以測試車輛的操穩(wěn)性與平順性。汽車試驗場試驗具有計算機(jī)仿真和室內(nèi)臺架試驗無法取代的重要實際意義,車輛測試設(shè)備在試驗場的應(yīng)用研究有助于提高車輛性能的測試與結(jié)構(gòu)設(shè)計合理性驗證的能力。長安大學(xué)汽車綜合性能試驗場,是全國高校唯一的汽車綜合試驗場,具有各種特殊試驗道路、操穩(wěn)性試驗廣場和高速環(huán)道等能夠完成全部汽車道路試驗的科研及檢測。目前傳統(tǒng)的汽車試驗儀器由于測試精度低,且容易受到外界干擾,對于測試結(jié)果的現(xiàn)場處理能力差導(dǎo)致測試結(jié)果不太理想。VBOX車輛測試系統(tǒng),基于高性能的GPS信號接收與強(qiáng)大的數(shù)字運(yùn)算協(xié)處理器,可與多種傳感器配合擴(kuò)展測試功能,通過配套軟件實現(xiàn)試驗數(shù)據(jù)實時查看與分析。論文選取長安大學(xué)汽車綜合性能試驗場探討VBOX與陀螺儀、方向盤測力計等儀器配合下的操穩(wěn)性試驗測試原理、設(shè)備安裝分析、設(shè)備精度與數(shù)據(jù)后期處理及測試精度提升途徑。通過選取試驗場的特殊試驗路段探討VBOX、LMS振動噪聲測試系統(tǒng)與陀螺儀配合下車輛特殊路面行駛過程平順性與駕駛室姿態(tài)角測試方法。經(jīng)由試驗過程分析探討VBOX在汽車試驗場環(huán)境條件下的測試及應(yīng)用的優(yōu)勢及不足分析,對高校開展相關(guān)測試研究具有一定參考意義。
[Abstract]:At present, due to the diversification of passenger and freight transport demand, there are many types of vehicles, the structure and use conditions of vehicles become more and more complicated, and the performance requirements of commercial vehicles are gradually improved. The requirements of vehicle performance detection are also paid attention to. The research on vehicle ride comfort and operating stability. It is mainly divided into two kinds: computer simulation test and road real vehicle test. The vehicle test ground condenses the actual road in the course of vehicle use and sets up various special roads. In order to test the running stability and ride comfort of the vehicle, the vehicle test field has the important practical significance that the computer simulation and the indoor bench test can not be replaced. The research on the application of vehicle test equipment in the test site is helpful to improve the capability of vehicle performance testing and structural design rationality verification. It is the only comprehensive test ground for automobile in colleges and universities all over the country, and has a variety of special test roads. Operation stability test square and high-speed loop can complete the scientific research and detection of all the vehicle road tests. At present, the traditional vehicle test instruments are easy to be interfered with by the outside world because of their low precision. For the test results of poor field processing ability, the test results are not ideal. VBOX vehicle testing system, based on high performance GPS signal reception and powerful digital coprocessor. The test data can be viewed and analyzed in real time by supporting software. VBOX and gyroscope are discussed in the vehicle comprehensive performance test field of Changan University. Steering wheel dynamometer and other instruments with the operation stability test principle, equipment installation analysis. The methods of equipment precision and data post-processing and test accuracy improvement are discussed. The VBOX is discussed by selecting the special test section of the test ground. The test method of ride comfort and cab attitude angle of vehicle special pavement under the cooperation of LMS vibration and noise measurement system and gyroscope. The measurement of VBOX in the environment of automobile test ground is discussed through the analysis of the test process. The advantages and disadvantages of trial and application are analyzed. It has certain reference significance to carry out relevant test research in colleges and universities.
