摘要:
本文叙述使用AppleⅡ微型机进行振动系统稳态正弦激励时的曲线拟合、参数识别及绘图,以及为提高识别精度,将拟合曲线对幅频特性再次进行优化拟合的原理,并将计算机计算结果与人工图解法的结果进行了对比,结果表明程序是可行的。利用AppleⅡ微型机作图,能在屏幕上直观地看到曲线拟合的过程,因此也能直观地判断测试结果的精确程度。
Abstract:
In this paper is described the use of Apple Ⅱ microcomputer to perform curve fitting, parameter identification and figure plotting for systems under steady state sinusoidal excitation conditions. In order to raise accuracy, the curve fitted can be fitted again in amplitude-frequency characteristics. Calculation results of Apple Ⅱ microcomputer are compared with thoseo brained by graphic method and the results show that the program is available. In using Apple Ⅱ to plot figures, we can see directly the procedure of curve fitting on the screen.
