【摘要】 基于气泡泡壁运动方程,详细研究了在双频声场驱动下的气泡非线性动力学振荡特性。系统地研究了外加声场参数的变化对气泡非线性动力学特性的影响,采用时域图、相图和分叉图等对该现象进行了详细描述,并进一步给出了气泡由线性振荡经过倍周期分叉发展为混沌振荡的详细动力学过程。更多还原

【Abstract】 In the present paper,the nonlinear behavior of gas bubbles under dual-frequency acoustic excitation is investigated based on the bubble interface motion equation.The main characteristics of excitation acoustic waves studied systematically here are the phase difference between two acoustic waves.The methods employed here for data analysis and demonstration include the time-domain plot,phase diagram and bifurcation diagram.The result shows that the periodical oscillating bubbles could become chaotic oscillation through the period-doubling mechanism.更多还原
