一、概述 曲轴弯曲疲劳试验在曲轴强度研究中起着很重要的作用,应用愈来愈广。为提高试验精度、采集曲轴断裂时的数据和减轻试验人员劳动强度,我们在1982年对我所的曲轴弯曲疲劳试验台应用微机系统作了初步的偿试。 二、曲轴弯曲疲劳试验微机自动化系统的组成及其工作原理 本系统采用8085A芯片作CPU,系统含有2K字节EPROM,6.25K字节RAM,8路模拟量输入,2路模拟量输出,以及小键盘、打印机、磁带机、时钟、循环计数器、QPS稳 First, an overview Crankshaft bending fatigue test plays a very important role in the study of crankshaft strength, more and more widely used. In order to improve the test accuracy, collect the data of the crankshaft rupture and reduce the labors’ labor intensity, we made a preliminary test on the application of microcomputer system to our crankshaft bending fatigue test bench in 1982. Second, crankshaft bending fatigue test computer automation system components and its working principle The system uses 8085A chip for CPU, the system contains 2K bytes EPROM, 6.25K bytes of RAM, 8 analog inputs, 2 analog outputs, and small Keyboard, printer, tape drive, clock, cycle counter, QPS stable
