本试验台是模拟汽车“起步”、换档时离合器的工况而设计的。本文着重介绍试验台的电测(程序控制、数据处理)系统的结构与工作原理。程控系统是整个试验装置的控制指挥系统,它把试验过程中的所有动作程序化,程序定值可调,精度高,并有自动保护装置。数据处理系统是实时数据处理系统,在试验过程中,边测试数据边处理结果,其试验结果以数字形式显示,并用微型打印机打印出来。 The test bed is to simulate the car “start”, the gear shift when the clutch conditions and design. This article focuses on the electrical test bench (program control, data processing) system structure and working principle. Program-controlled system is the pilot unit of the control command system, which tests all the procedures during the program, adjustable program settings, high precision, and automatic protection device. The data processing system is a real-time data processing system. During the test, the results are processed while testing the data. The test results are displayed in digital form and printed out by the mini-printer.
