| 摘 要： | 脉冲电场作用下,乳化油中乳胶粒子会发生长球状的伸缩振动,但目前对于粒子振动的研究较少.通过建立乳胶粒子振动的动力学模型得出粒子的非线性参激振动方程,对振动阻力和恢复力系数进行函数逼近处理,运用谐波平衡法对振动方程进行计算,得到粒子振动的一次近似解以及幅频特性曲线.数值实验表明,粒子振幅的一次近似解与振动方程的四阶Run...

| Abstract: | In pulse electric field,flexing deformation and vibration of latex particle,taking on an ellipsoid,happen in emulsion oil.So far,the research of particle’s vibration has been lack.By establishing dynamics model of single latex particle,the equation of its parametrically excited nonlinear vibration is obtained.Functions of resistance and resilience coefficients on particle’s vibration are disposed by approach and predigestion.Calculating vibration equation by harmonious wave balance solution,particle vibration’s simple approximate expression and curves of swing-frequency characteristic are obtained.Numerical value test shows that simple approximate expression of particle vibration is close to result by 4-order Runge-Kutta,which can prove the method for calculation of parametrically excited nonlinear vibration on latex particle is reasonable. |
