研究的新型光电函数发生器是直接利用焊接热循环等函数图形作为光路元件,按热过程函数曲线改变光通量的大小,从而使光电池连续输出一个与热函数一致的电函数信号的装置。这种光电函数发生器具有结构简单、经济、灵敏度高、功能广泛等特点。除焊接热循环外,也可作为应力、应变循环、恒热、热疲劳等热过程的程序给定装置。 The new type of photoelectric function generator is a device which directly uses the function graph such as welding thermal cycle as the optical path element and changes the luminous flux according to the curve of the thermal process so as to make the photocell continuously output an electric function signal which is consistent with the thermal function. This photoelectric function generator has the advantages of simple structure, economy, high sensitivity and wide range of functions. In addition to welding thermal cycle, but also as stress, strain cycle, constant heat, thermal fatigue and other thermal process given device.
