基于PLC和计算机的汽车同步器测试系统

Testing system of automobile synchronizer based on PLC and computer

同步器是汽车变速箱的核心部件,其性能对汽车变速箱以及汽车性能的提高有着重要意义。为了评价汽车变速器中同步器的性能与寿命,相应设计了基于PLC和计算机共同控制的测试系统;计算机主要完成人机界面交互任务以及相关数据的分析与存储,PLC根据计算机命令实现数据实时采集和对整个系统的实时控制;测试系统能够进行三类长时间、高重复性的主要测试,运行稳定可靠。本文主要介绍了测试系统的组成结构、系统设计、PLC在测试系统中的应用和控制程序设计。

Because the synchronizers are the core part of automobile gearbox,it has important significance for the performance of both automobile and automobile gearbox.To evaluate the performance and longevity of automobile synchronizer,a PLC and computer based testing system is developed.The computer is used to complete the task of man-machine interface interaction,analysis and storage related data.The PLC is use to real-time gather data and real-time control,according to orders coming from the computer.The testing system can achieve three types of long-time and high-repeated tests and keep its operation stable and reliable.This paper presents its structure,control system design,application of PLC and control program design.
