摘要

本文关注的是 Timoshenko 梁的端口-哈密顿模型，该梁通过 von Kármán 应变受到几何非线性影响，材料非线性考虑了新胡克或穆尼-里夫林材料假设下的超弹性，此外还有与体积保持一致的不可压缩变形约束。该模型适用于在中等变形和旋转范围内表示类似橡胶梁的行为。为了说明所提议模型的准确性，我们进行了数值模拟。

Port-Hamiltonian modeling of a geometrically nonlinear hyperelastic beam⁎

This paper is concerned with the port-Hamiltonian modeling of a Timoshenko beam subject geometric nonlinearities through von Kármán strains, material nonlinearity considering hyperelasticity with the assumption of neo-Hookean or Mooney-Rivlin material, in addition to the incompressible deformation constraint that corresponds to the preservation of volume. The model is suitable for representing the behavior of rubber like beams within the range of moderate deformations and rotations. Numerical simulations are carried out to illustrate the accuracy of the proposed model.
