    Abstract
  • Overload is the real environment of launch vehicles. The variable-coefficient transverse differential equation for the free vibration of Euler beam under longitudinal overload was derived on the basis of the Hamiltonian principle. For the variable-coefficient dynamic system, the existence of eigensolutions satisfying the orthogonal conditions of mass and stiffness was proved, and the asymmetry of such eigenfunction was revealed. A modified Euler symplectic midpoint difference method and a modified mode superposition method were employed to solve the equation of variable-mass systems. The numerical results of the two methods agree well, and validate the correctness of present theory and feasibility of the two methods.
