RC电路正弦稳态特性的Multisim仿真分析

Multisim simulation analysis of the RC circuit sinusoidal steady-state characteristics

基于探索大学物理电学实验仿真技术的目的,采用Multisim10仿真软件对RC电路正弦稳态特性进行了仿真实验分析。用多个四踪示波器以面板部分重叠方式显示电路中各电量的波形,可直观观测稳态时各电量的相位关系,定量测量反映超前、滞后关系的相位差及各电量的数值大小。将电路的硬件实验方式向多元化方式转移,利于培养知识综合、知识应用、知识迁移的能力,使电路分析更加灵活和直观。

The RC circuit sinusoidal steady-state characteristics were analyzed through Muhisim 10 in the paper which aims to explore simulation technology of physical electrical experiments in university. All circuit signal waveforms were displayed in section overlapping show by using multi-four-track oscilloscopes. The relation of electrical phase place in steady-state can be directly observed on the screen. The lead or lag of phase difference and value of each circuit＇s electricity can be also exactly measured. It＇s good for ability training of integrating, applying and migrating knowledge and obtains more flexible and intuitive circuit analysis by diversified transferring pattern of circuit＇s hardware experiment.
