摘　　要：电路的暂态过程是电路从一种稳态变化到另一种稳态的过渡过程,其研究对预防换路过程中产生的过电压和过电流,甚至利用其产生特定波形的电信号都具有重要意义。针对电路理论分析中由开关断开或闭合及元件参数变化引起的看不见摸不着的电路响应变化,利用Lab VIEW软件平台完成了暂态电路的仿真设计,虚拟实现了一阶暂态电路分析和不同电源模式下二阶暂态电路的仿真设计。通过自定义控件的方式,用户不但可以方便快捷地搭建电路模型,还可通过变化控件值直接改变电路参数,由此产生的响应变化随即以数值、波形或表格等形式直观地显示在界面上,从而加深了对电路定理和规律的理解和掌握。Transient process of the circuit is a transition process that the circuit changes from a steady state to another steady state; the research on it is of great significance on the prevention of overvoltage,over-current and even electrical signals of specific waveforms during the circuit changing. Aiming at the abstract circuit response caused by the parameter variation of the components of the circuit theoretical analysis,this paper has designed a simulation of the transient circuit on the Lab VIEW platform to accomplish the analysis of the first-order transient circuit and the second-order transient circuit in simulation under different power source modes. Through the custom control mode,the user could make up circuit model quickly and conveniently,but also could change the circuit parameter of the component by changing the value of the control and thus the respective change will be presented on the window in the form of values,waveforms or a table. As a result,the students＇ understanding to the circuit analyzing method was enhanced.
