摘要：
对集中质量模型的动力吸合进行了分岔分析。弹簧的恢复力是基于非线性本构应力-应变定律导出的，弹簧上的质量块的驱动力是基于静电库仑力导出的。分析所产生的非线性弹簧质量方程的初始条件。给出了周期解存在的充要条件，并给出了数值例子。确定了与二阶弹性刚度常数和电压相关的参数上的歧点的条件。
英文摘要：
Bifurcation analysis of dynamic pull-in for a lumped mass model is presented. The restoring force of the spring is derived based on the nonlinear constitutive stress-strain law and the driving force of the mass attached to the spring is based on the electrostatic Coulomb force, respectively. The analysis is performed on the resulting nonlinear spring-mass equation with initial conditions. The necessary and sufficient conditions for the existence of periodic solutions are derived analytically and illustrated numerically. The conditions for bifurcation points on the parameters associated with the second-order elastic stiffness constant and the voltage are determined.
