摘　　要：电子模拟计算机,动力学,等效实验,仿真,非线性时变系统基于电学和动力学的广泛相似性,针对动力学实验复杂、可观测性差的实际,用电子模拟计算机实现动力系统的传递函数和基本算子,将动力学实验问题转化为电问题,从而可以利用成熟的电测量技术完成动力系统的仿真和实验.给出了基于电子模拟计算机的动力系统的基本元件的等效模型、典型动力系统的等效模拟和等效实验系统构架.模拟及仿真结果表明,文中方法简单、正确,应用范围广.Aimed at hardness of espial and complexity of the electronic analog computer is employed to implement technology in the experiment of dynamic systems, the transfer function and primitive operator of dynarnic systems from viewpoint of control theory for the general equality between electricity and dynamics, in this way the dynamic experiment changes into electricity experiment and the ripe technology of electricity measure can be used in the simulation and experiment of dynamic systems. Based on the electronic analog computer, the electronic equivalent models of essential elements of dynamical systems are given, and the electronic equivalent analogue operation and electronic experimentation framework of typical dynamical systems are given too. The results of simulation and analog show that the method is simple and correct, and the scope of its application is wide.
