使用计算机控制试验设备后,可以极大地简化数字随机过程应用于持久试验及低频疲劳。为此目的,把一台数字计算机接到闭环材料试验系统中(图1)。计算机程序地给出指令函数,通过伺服操纵反馈来控制试验,并获得衰减数据和记录数据。本文所叙 The use of computer controlled test equipment can greatly simplify the use of digital stochastic processes for long-term testing and low-frequency fatigue. For this purpose, a digital computer was connected to a closed loop material testing system (Figure 1). Computer program to give the command function, servo control feedback to control the test, and to obtain attenuation data and record data. This article describes
