中文摘要:为满足乘用车驻车制动系统人机优化设计需要,设计了基于转毂试验台的驻车制动动力学性能测试系统并进行性能评价方法研究。首先,建立了在转毂试验台上进行等效驻坡度的测试模型。其次,构建了以美国NI嵌入式控制器cRIO及其C模块为核心的测试系统,对手柄力传感器和角位移传感器进行选型,设计了安装夹具以满足车上通用性安装要求。基于LabVIEW对数据采集器和上位机进行编程,实时可靠地实现数据采集、处理、通讯和人机交互等功能。再次,进行了测试方法研究,综合考虑了弹性元件回弹、制动毂或盘的表面状态、加工工艺等影响因素,引入概率统计方法对驻车制动性能进行评价。最后,进行了系统的实车试验,结果表明设计的测试系统能够可靠工作,满足既定要求。研究表明提出的基于转毂试验台的乘用车驻车制动性能测试与评价方法是有效可行的。

Abstract:In order to meet the requirements for human machine optimization design, the dynamic test system was designed based on the chassis dynamometer, which was used to evaluate the parking brake performance of passenger vehicle. Firstly, the feasibility analysis was conducted for the test scheme, and the test model for the equivalent angle of parking slope was put forward. Then, the test system was designed, in which the CompactRIO (cRIO) controller and the related C modules made by National Instrument Company of America were selected as the core components. Under the consideration of the general installing requirements, both the handle force sensor and the angle sensor were selected, and their related mounting brackets were designed. Besides, the LabVIEW was employed to program the code for the controller and the host computer, in which the functions, such as data collection, data processing, communication and GUI, were conducted reliably in real time. Thirdly, the test method was explored, in which these influence factors were taken into consideration, such as elastic elements rebound, surface state of brake drum or disk, processing technology. In particular, the method of probability and statistics were introduced to evaluate the parking brake performance. Finally, the test system was used to conduct several tests and it worked reliably, and it met the design requirements. The result showed that it was effective and plausible for the dynamometer based test system and the evaluation method proposed for the parking brake performance of passenger vehicle.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
