A hybrid method of component mode synthesis

Efficient Component Mode Synthesis with a New Interface Reduction Method

When the finite element model of a complex structure is partitioned into substructures in order to enable component mode synthesis (CMS), there may be a large number of degrees of freedom (DOF) on the interface between components. In such a case, the constraint-mode-related coordinate transformation at the substructure analysis stage becomes computationally expensive, and the CMS model may be c...

A Special Finite Element Method Based on Component Mode Synthesis

The goal of our paper is to introduce basis functions for the finite element discretization of a second order linear elliptic operator with rough or highly oscillating coefficients. The proposed basis functions are inspired by the classic idea of component mode synthesis and exploit an orthogonal decomposition of the trial subspace to minimize the energy. Numerical experiments illustrate the ef...

تحلیل مودال با استفاده از روش component mode synthesis (cms) همراه با صحه گذاری تجربی

در این پروژه روش های تحلیل مودال سازه هایی که از چند زیرسازه تشکیل شده اند بررسی شده است. از جمله این روش ها روش سنتز مودها است که ابتدا بطور مختصر تاریخچه فعالیت هایی که در این زمینه تا کنون انجام شده است بررسی شده و سپس الگوریتم های مختلف این روش مورد مطالعه قرار گرفته است. از جمله این الگوریتم ها روش سطوح مشترک ثابت و روش سطوح مشترک آزاد است طوریکه روش اول با دقت بیشتر و تنها برای داده های ت...

Overlapping Component Mode Synthesis

A Three-Component Hybrid Image Compression Method

In this paper we present a case study of a three-component hybrid image compression algorithm combining the widely familiar, DCT-based JPEG algorithm with the Wavelet-based JPEG 2000 algorithm and a searchless fractal image compression algorithm capable of unusually deep quadtree spanning. Comparison of the relationship between compression rate and peak signal to noise ratio for each component ...
