| Abstract: | This paper has introduced a general form of dynamic equations ot shimmy including structural elastic deformation and results in anfeigenvalue problem by the method of phase-space in a non-self-adjoint system.The numerical examples show that the method is effective and the results are satisfactory. |
| |
| Keywords: | shimmy eigenvalue phase-space non-self-adjoint system. |
