摘要
本文证明了两条定理,即相容质量阵定理和相容刚度阵定理,为结构分析模型的改进问题(AMI)提供了完备解集.应用定理,本文建立了可以满足充分反映结构物理和几何特点的各种约束条件的精细校正方法.
Two theorems:compatible mass matrix theorem and stiffness theorem;have been proved in this paper,Using the theorems,the authers have established a set of complete solutions for structure analysis model improvement(AMI)and a fine correction method which can satisfy all the constraint conditions that fully reflect the physical and geometric characteristics of a structure.
