Lanczos向量叠加法及其在结构动力分析中的应用

Lanczos Vector Superposition Method and its Dynamic Analysis

在修正的Ritz向量直接叠加法与Lanczos坐标法的基础上,发展了Lanczos向量叠加法,并用算例分析了Lanczos向量及其对应频率的特性,以及Lanczos向量叠加法对结构动力分析的有效性,提出了相缨赌误差估计方法。

An improved Lanczos Vector Direct Superposition Method for dynamic analysis based on RITZ Vector Superposition and Lanczos Coordinate Method is presented.And an error norm is.studied.Numerical results show that this Method and the corresponding error norm are efficient for dynamic analysis.
