In this paper, the theory of nonlinear electroelasticity is used to examine deformations of a dielectric elastomer tube, reinforced by two families of helical fibers with different angles, with closed ends and compliant electrodes on its side surfaces. To illustrate the behavior of the fiber-reinforced tube, a specific form of electroelastic energy function is used for numerical purposes. Numerical dependences of the deformation on the non-dimensional potential difference between electrodes are obtained for the considered energy function. The influence of fiber stiffness and their angles on a response of the tube are analyzed. The presented theory and results may be of value in the development of soft robots and actuators.

在本文中，非线性电弹性理论用于检查介电弹性体管的变形，该管由两组不同角度的螺旋纤维增强，其侧面具有封闭端和柔顺电极。为了说明纤维增强管的行为，使用特定形式的电弹性能量函数进行数值计算。对于所考虑的能量函数，获得了变形对电极之间无量纲电位差的数值依赖性。分析了纤维刚度及其角度对管响应的影响。所提出的理论和结果可能对软机器人和执行器的开发具有价值。
