the proof of its unconditionally stable requires no damping matrix to satisfying the condition of the orthogonality of modes.
法的无条件稳定性的证明,可不要求阻尼矩阵满足振型正交条件。
the estimations of maximum norm of damping matrix are also considered.
研究了阻尼矩阵的最大模估计。
dynamics theory and the 「mass-spring-dashpot」 system model were used to develop an equilibrium equation. the mass matrix, elasticity matrix and damping matrix were given.
according to the structural properties and the vibration displacement of the box girder bridge, the element space damping matrix of the box girder bridge is derived on the principle of energy.
