摘要
利用数字式计算机和模拟计算机,对多频激励Duffing振子进行了数字仿真和实时仿真试验研究,研究了系统的共振类型和其共振域范围,得到了理论预测的全部共振解.
This paper presents the investigation of digital simulation and real-time simulation with an analogical computer for a multi-frequency excited Duffing's oscillator. Various resonances and their resonance regions are obtained for different frequency ratios k. All the theoretically forecasted resonances for k=2 are obtained.
