| 摘 要： | 研究受简谐激励的两条长直电流间载流导线的主共振问题,应用动力学方法建立载流导线受外部激励和安培力的Duffing方程。根据非线性振动的多尺度解法,得到了系统满足主共振情况的近似解以及对应的定常解,并对其进行了数值计算。分析了电流、调谐值、张力、激励等对系统的影响。

| Abstract: | Primary resonance of current-carrying conductor subjected to harmonic excitation and ampere force system are studied. The Duffing equation of the system is established by means of principles in dynamics. According to the method of multiple scales for nonlinear vibrations, the approximation solution for primary resonance of the system is obtained. Numerical analysis on the influence of current, detuning, tension, and excitation applied on the system is carried out. |
