摘要

DHF-1型可调相位多功能函数发生器的所有波形的频率、相位、波形正负斜率以及脉冲宽度都是连续可调的.它能产生正弦、矩形、三角、梯形、正负锯齿等连续波形;还能产生斜波、阶跃波和正负斜率、脉冲宽度可独立调谐的单周期任意波.多功能函数发生器如同程序机那样

是为土动三轴团环伺服控制试验系统设计研制而成的.在下列试验程序中有特殊的作用:拉力试验、断裂力学、低周疫劳、疲劳、应力缓和、蠕变、高速冲击和振动等试验.

Abstract

Model DHF-1 variable-phase versatile function generator is an apparatus in which positive or negative slope and pulse width could be adjusted continually. The versatile function generator can produce continuous waveforms such as sinusoidal

square

triangular

trapezoidal

positive and negative saw-tooth etc. It can also produce ramp

step waves and single-cycle arbitrary wave independently adjustable to both positive or negative slope and pulse width. The versatile function generator is specially designed as a programmer for dynamic triaxial closed-loop servo-controlled testing systems. It may be specifically applied to the following tests: tensile

fracture mechanics

low-cycled fatigue

fatigue

stress relaxation

creep

high-velocity shock and vibration.
