1. Reduced Order Modeling and Substructuring : Applications in Nonlinear Structural Dynamics
Sammanfattning : A structural design process typically involves various load cases for which a sufficient load-bearing capacity must be demonstrated. In addition to static load cases, a verification of dynamic loads, such as blast and impact loading, may be required. LÄS MER
2. Hybrid and Dynamic Substructuring Methods for Energy Flow Analysis
Sammanfattning : Modeling techniques and solution tools to analyze the dynamic and vibro-acoustic behavior of complex built-up structures are matters of increasing interest, especially for thin walled structures as in transportation vehicles, such as automobiles, trucks, trains and aircraft. In structures like these, the reduction of cost, weight, sound and vibration levels are primary issues for research and development. LÄS MER
3. Identification and Synthesis of Components for Vibration Transfer Path Analysis
Sammanfattning : Transmission of structure-borne vibrations in built-up structures, e.g. vehicles such as aircraft, automobiles and trains, is addressed. Methodologies for modeling, analysis, prediction and reduction of vibrations are developed. LÄS MER
4. Statistical Energy Analysis and the Individual Case
Sammanfattning : For many years, one of the most used methods for vibro-acoustic analysis of transmission of Structure-Borne Sound in complex built up structures has been the method of Statistical Energy Analysis (SEA). SEA has many advantages that makes it attractive for engineering use. LÄS MER
5. Structure-acoustic analysis; finite element modelling and reduction methods
Sammanfattning : This thesis investigates structure-acoustic systems by use of finite element analysis. The systems studied here are limited to those that consist of an enclosed acoustic fluid cavity, which is coupled to a flexible structure and/or a porous sound absorbing material domain. LÄS MER
