黑龙江工程学院本科生毕业设计 1 附 录 附录 A 英文文献 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 黑龙江工程学院本科生毕业设计 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. 黑龙江工程学院本科生毕业设计 3 附录 B 中文翻译 试验台设计 汽车试验是伴随其工业的建立和发展而逐渐成长起来的，汽车工业发展到今天与其试验研究工作是分不开的。试验是帮助我们了解汽车实际使用中的规律，并推动其技术进步的一种极为重要的方法。它是保证产品性能，提高产品质量和市场竞争力的重要手段。 本文研究了汽车变速器性能试验装置 闭式功率流变速器试验台 的结构和控制系统。主要分为机械结构部分和控制部分两大部分来进行。机械结构部分首先介绍了闭式功率流变速器试验台的主要结构、特点及其工作原理，并分为变速系统、加载系统和传动系统等进行了结构设计，选择了电机和传感器。控制部分介绍了 AVR单片机的特点以及选用原则，确定了整个控制系统的方案。整个控制系统分为硬件和软件两部分设计。硬件部分分别进行了驱动电路、复位电路、 A/D 转换电路和键盘显示电路等的设计。软件部分根据变速器性能试验的模式进行了主程序及各项试验子程序、 A/D 转换子程序、键盘显示子程序、中断子程序等各子程序 的设计。最终进行了电路板的制作和系统的调试，模拟了整个试验的过程。该变速器性能试验台操纵方便、输入记时准确、试验结果表达清楚、可靠性高。从理论上来看，汽车变速器性能试验台控制系统在变速器机械效率实验中运行是稳定可靠的，操作是比较简便的，具有一定的抗干扰能力，基本达到了变速器实验台的控制要求。 汽车变速器是汽车传动系统中的主要部件之一，变速器工作状况的好坏直接影响到汽车整体性能，对变速器的检测至关重要。本文在系统分析了汽车变速器性能、功用、要求的基础上，综合机械、液压、电气三个方面，设计了汽车变速器总成交检试验台，完成汽车变速器的下线加载检验。在该试验台中设计了输入轴驱动和输出轴驱动装置。输入轴驱动 (正拖 )完成在不同档位时的变速器噪声检测；输出轴驱动 (反拖 )进行不同档位换档测试。输入端电机转速调节由变频器来完成，输出端电机转速及扭矩设定通过伺服系统实现。通过电气控制系统控制输入端电机、输出端电机反复动力切换，来
