| 摘 要： | 运用混沌脉冲调制方法构建混沌频率脉冲电场，建立乳化油液滴在混沌频率电场中的振动动力学仿真模型，通过数值计算，得到油中液滴在混沌频率脉冲电场作用下的振动动力学响应，并对响应输出进行了相轨图分析和最大Lyapunov指数计算。结果发现，混沌频率脉冲电场存在最佳脉宽，激励液滴剧烈振动；液滴在高频段获得较大拉伸变形量，在低频段则拉伸变形量相对较小，且波动稳定；可定性和定量地识别液滴振动响应的混沌特征。

| Abstract: | The chaotic frequency pulse electric field is
constructed by using the Chaotic-Pulse-Position Modulation method, and the
vibration dynamics simulation model of emulsion droplets in the chaotic
frequency electric field is established. Through numerical calculations, the
vibration dynamic response of the droplet in the oil under the action of the
chaotic frequency electric field is obtained and the phase orbit diagram
analysis and the maximum Lyapunov exponent calculations are carried out for the
response output. It is found that the pulse electric field with chaotic
frequency has the best pulse width, which can excite the droplet to vibrate
violently. The droplet gets a large amount of tensile deformation at high
frequency, but relatively small at low frequency, and the fluctuation is
stable, which can qualitatively and quantitatively identify the chaotic
characteristics of the droplet vibration response. |
