摘要
在高温真空力学试验系统的加热方式中,目前通常采用辐射加热、通电加热及感应加热。辐射加热的效率相对较低,受发热体的约束,加热温度很难超过2500℃。通电加热是以试样作为发热体,可实现3000℃超高温加热。本文采用通电加热的方式,以嵌入式系统作为控制核心,运用经典PID算法,能够快速实现对温度的稳定控制。
Among the heating methods of high temperature vacuum mechanical testing system,radiation heating,electric heating and induction heating are usually used at present.The efficiency of radiation heating is relatively low,and the heating temperature is difficult to exceed 2500℃due to the restriction of the heater.The electric heating uses the sample as the heating element,which can realize the ultra-high temperature heating of 3000℃.This paper adopts the way of electric heating,with embedded systems as the control center,and uses the classical PID algorithm to realize the temperature control quickly.
