本文计算了弯曲波和轴向波在非线性变形区沿受电弓横梁传播时的幅值相关色散关系。受电弓横梁的动能由均匀化得到,其中包括一个梯度的微惯性贡献。在无限小振幅行波的极限下,恢复了已知的线性形变区与振幅无关的波色散关系。我们的分析认为,在受电弓波束中观察到了奇异波的传播,值得进一步研究。
In this paper, amplitude-dependent dispersion relations for flexural and axial waves travelling along a pantographic beam in non-linear deformation regime are computed. The kinetic energy of the pantographic beam, including a gradient micro-inertia contribution, is derived by homogenization. In the limit of travelling waves with infinitesimal amplitude, well-known amplitude-independent wave dispersion relations for linear deformation regime are recovered. Our analysis concludes that exotic wave propagation is observed in pantographic beams and deserves further studies.
