黑龍江工程學(xué)院本科生畢業(yè)設(shè)計(jì) 1 附 錄 附錄 A 英文文獻(xiàn) Design of test Automotive test is the industry with the establishment and development of and gradually grow up, the auto industry development today with experimental research work is part of it. Test is help us understand the actual use of the car, and promoting the rule of progress a kind of very important methods. It is the guarantee product performan, improve product quality and market competitiveness of the important means. This paper studies the auto transmission performance test devices, power flow of the test bed of closed transmission structure and control system. Mainly divided into mechanical structure and control part two of most. Mechanical structure parts first introduced the power flow of the test bed of closed transmission main structure, characteristics and working principle, and divided into variable speed drive system, loading system and transmission system of structure design, select the motor and sensors. The control part introduces the characteristic and single-chip microcomputer AVR, and the selection principle of the control system of the scheme. The whole control system is divided into two parts of the hardware and software design. Hardware, the driver circuit and reset circuit, A/D circuit and keyboard display circuit design. Software in part on the transmission performance test model for the main program and the test procedure, A/D conversion subroutines, keyboard display subroutines, interrupt the subroutine subroutine design. The final of the circuit board production and system commissioning, the whole process of the simulation test. The transmission performance test rig manipulation convenient, input timing accurate, test results clearly, high reliability. In theory, see from auto transmission performance test rig control system in the transmission efficiency of experimental operation is stable and reliable, the operation is simple, with certain antijamming ability, basic reached the transmission control requirements for test bench. Auto transmission is the auto transmission system, one of the main components of the transmission of working condition of the direct influence on the overall performance of the transmission car, the test is very important. Based on the systematic analysis of the auto 黑龍江工程學(xué)院本科生畢業(yè)設(shè)計(jì) 2 transmission performance, functions, requirements, and on the basis of comprehensive machine, hydraulic, electric three aspects, design the auto transmission assembly JiaoJian test rig, complete the auto transmission referral loading inspection. On the bench in the input shaft drive design and output shaft drive device. Input shaft drive (is) in different gear finish off the transmission noise detection； The output shaft drive (the drag) different gear shift test. Input the motor speed adjustment by frequency converter to complete, the output torque motor speed and set through the servo system implementation. Through the electrical control system control input motor, the output power switch, motor repeatedly to simulate the car conditions. At the same time, the test bench in the design of hydraulic system used to control the transmission of clamping, to the transmission of the row of lubricant, input the clutch stoopped.press closed, the output of the tailstock a； The design of the input assembly institutions, output assembly institutions and special note the soot device transmission. Through the industrial realized the servo controller, frequency conversion control, PLC and data communications between each instrument and the output of the data report, reached the real-time control. Sensor system and instrumentation output shaft torque, complete input and output terminal speed, the transmission noise, note the soot flow, the oil temperature and so on a measurement and monitoring. This test rig and reasonable structure, the function is all ready, convenient operation, with a precision complete digital display system. 黑龍江工程學(xué)院本科生畢業(yè)設(shè)計(jì) 3 附錄 B 中文翻譯 試驗(yàn)臺(tái)設(shè)計(jì) 汽車試驗(yàn)是伴隨其工業(yè)的建立和發(fā)展而逐漸成長起來的，汽車工業(yè)發(fā)展到今天與其試驗(yàn)研究工作是分不開的。試驗(yàn)是幫助我們了解汽車實(shí)際使用中的規(guī)律，并推動(dòng)其技術(shù)進(jìn)步的一種極為重要的方法。它是保證產(chǎn)品性能，提高產(chǎn)品質(zhì)量和市場競爭力的重要手段。 本文研究了汽車變速器性能試驗(yàn)裝置 閉式功率流變速器試驗(yàn)臺(tái) 的結(jié)構(gòu)和控制系統(tǒng)。主要分為機(jī)械結(jié)構(gòu)部分和控制部分兩大部分來進(jìn)行。機(jī)械結(jié)構(gòu)部分首先介紹了閉式功率流變速器試驗(yàn)臺(tái)的主要結(jié)構(gòu)、特點(diǎn)及其工作原理，并分為變速系統(tǒng)、加載系統(tǒng)和傳動(dòng)系統(tǒng)等進(jìn)行了結(jié)構(gòu)設(shè)計(jì)，選擇了電機(jī)和傳感器?？刂撇糠纸榻B了 AVR單片機(jī)的特點(diǎn)以及選用原則，確定了整個(gè)控制系統(tǒng)的方案。整個(gè)控制系統(tǒng)分為硬件和軟件兩部分設(shè)計(jì)。硬件部分分別進(jìn)行了驅(qū)動(dòng)電路、復(fù)位電路、 A/D 轉(zhuǎn)換電路和鍵盤顯示電路等的設(shè)計(jì)。軟件部分根據(jù)變速器性能試驗(yàn)的模式進(jìn)行了主程序及各項(xiàng)試驗(yàn)子程序、 A/D 轉(zhuǎn)換子程序、鍵盤顯示子程序、中斷子程序等各子程序 的設(shè)計(jì)。最終進(jìn)行了電路板的制作和系統(tǒng)的調(diào)試，模擬了整個(gè)試驗(yàn)的過程。該變速器性能試驗(yàn)臺(tái)操縱方便、輸入記時(shí)準(zhǔn)確、試驗(yàn)結(jié)果表達(dá)清楚、可靠性高。從理論上來看，汽車變速器性能試驗(yàn)臺(tái)控制系統(tǒng)在變速器機(jī)械效率實(shí)驗(yàn)中運(yùn)行是穩(wěn)定可靠的，操作是比較簡便的，具有一定的抗干擾能力，基本達(dá)到了變速器實(shí)驗(yàn)臺(tái)的控制要求。 汽車變速器是汽車傳動(dòng)系統(tǒng)中的主要部件之一，變速器工作狀況的好壞直接影響到汽車整體性能，對(duì)變速器的檢測至關(guān)重要。本文在系統(tǒng)分析了汽車變速器性能、功用、要求的基礎(chǔ)上，綜合機(jī)械、液壓、電氣三個(gè)方面，設(shè)計(jì)了汽車變速器總成交檢試驗(yàn)臺(tái)，完成汽車變速器的下線加載檢驗(yàn)。在該試驗(yàn)臺(tái)中設(shè)計(jì)了輸入軸驅(qū)動(dòng)和輸出軸驅(qū)動(dòng)裝置。輸入軸驅(qū)動(dòng) (正拖 )完成在不同檔位時(shí)的變速器噪聲檢測；輸出軸驅(qū)動(dòng) (反拖 )進(jìn)行不同檔位換檔測試。輸入端電機(jī)轉(zhuǎn)速調(diào)節(jié)由變頻器來完成，輸出端電機(jī)轉(zhuǎn)速及扭矩設(shè)定通過伺服系統(tǒng)實(shí)現(xiàn)。通過電氣控制系統(tǒng)控制輸入端電機(jī)、輸出端電機(jī)反復(fù)動(dòng)力切換，來
