| 摘 要： | 本文研究一般线性阻尼系统的振动问题。仅假定系统的质量矩阵非奇异,将系统模态的加权正交关系式作了拓广,并利用相互等价的一次本征方程与二次本征方程间的转换关系,简捷地求得了预解式的各种模态展开式。

| Abstract: | The vibration problem of general linear damped systems is discussed in this paper. It's only assumed that the mass matrice is nonsingular. The weighted orthogonality formulas of the system modalities are extended, and using mutual equivalent conversion relationship between the eigen equations of 1-st degree and 2-nd degree, the complex modal expansion formulas of the resolvents are obtained simply and rapidly. |
