摘要

聚氯乙烯(PVC)凝胶在交流电压激励下会产生复杂的非线性振动行为,具有作为动态机电致动器的潜在应用价值。然而,关于聚氯乙烯凝胶致动器的变形理论,尤其是动态非线性响应理论的研究很少。本文根据 PVC 薄膜的电变形机理建立了一个复杂的动态模型,并通过微分方程对致动器的非线性动态行为进行了数值研究。在双轴拉力相等的条件下,分析了外加电压振幅、电压频率、己二酸二丁酯含量、机械拉力和偏置电压对 PVC 薄膜动态特性的影响。利用时域特性分析了振幅的变化以及振动过程中节拍频率的产生和消失。此外,还根据相位路径和 Poincare 地图反映了 PVC 激励器的非线性程度以及振动稳定性和周期性。最后,得出了外部条件参数对 PVC 激励器动态响应的影响规律。

Deformation theory and nonlinear dynamic behavior of PVC gel actuators
Polyvinyl chloride (PVC) gel generates complex nonlinear vibration behavior under an alternating current voltage excitation, which has potential application as a dynamic electromechanical actuator. However, there are few studies on the deformation theory of PVC gel actuators, especially the dynamic nonlinear response theory. In this paper, a complex dynamic model is established according to the electrodeformation mechanism of PVC film, and the nonlinear dynamic behavior of the actuator is numerically studied by a differential equation. The effects of applied voltage amplitude, voltage frequency, dibutyl adipate content, mechanical tension, and bias voltage on the dynamic properties of PVC film were analyzed under the condition of equal biaxial tension. The variation of amplitude and the generation and disappearance of the beat frequency during vibration are analyzed by using time-domain characteristics. The degree of PVC actuator nonlinearity as well as vibration stability and periodicity is also reflected based on the phase path and Poincare map. Finally, the law of influence of external condition parameters on the dynamic response of the PVC actuator is obtained.
