Content, Learning Outcome and Preconditions

Content

The course aims at impartion of fundamental knowledge about modeling of discrete systems and finite element method (FEM) in vibroacoustic problems. Throughout the course, students will:

- use ABAQUS/CAE as a commercial finite element software (especailly used in the automotive industry*) to perform a finite element simulation
- analyze and evaluate analytical and numerical results
- perform an examination of parameter and model values
- Validate finite element models with experimental data

The course is divided into two parts:
- Methodical approach to virtual mapping of physical behavior of simple monolithic structures
- Construction of individual assemblies of a simplified gear-box

* ABAQUS is not only used in automotive industry. It is a very commonly used software for any FEM problem.

Learning Outcome

At the end of the course the student must be able to:

- Develop a virtual model for a real structural dynamics problem;
- Estimate the accuracy and the reliability of the model;
- Evaluate the model with the help of available measurement data;
- Analyze different effects of model and parameter uncertainties on the solution;
- Demonstrate the limits of analytical and numerical models;
- Use ABAQUS/CAE as a commercial FE-software and understand the complete structure of the program

Courses and Schedule

Learning and Teaching Methods

The physical, mathematical and methodical fundamentals of different analytical and numerical models will be presented to students. The students will the use the fundamental approaches to build a virtual model in ABAQUS/CAE in the form of a supervised computer assignment. Documents and tutorials will be provided to students to assist them with independent further training. This will help students to have confidence in working with the virtual model, in which they independently estimate the parameter and model uncertainties and demonstrate their effects on the model solution. In a final project, students will work on a more complex problem consisting of a simplified engine-transmission assembly. This project will help students to gain a robust knowledge in the field of structural dynamics, understand the complexity of these problems and to work comfortably in ABAQUS/CAE environment. In addition, students will validate their numerical results with available experimental data.

Module Exam

Description of exams and course work

The examination is in from of excercises (practical work). The students will do short coding/modeling task during the first lectures. The students have to document the results and findings in form of a report. Thus, the capability of modeling vibroacoustic problems with ABAQUS/CAE and the meaningful interpretation of the results is demonstrated. The number of required reports will be announced at the beginning of the lectures. The acquired knowledge during the lectures prepare the students to solve more complex tasks. Along with the lectures, a complex project with focus on modeling vibroacoustic problems of engines have to be prepared. In a final report, the students show proficiency to solve complex vibroacoustic tasks.
The final mark is calculated as follows: Arithmetic mean of the reports is weight with 30%, the final report of the complex task is weighted 70 %.

Exam Repetition

There is a possibility to take the exam in the following semester.
