- Contents
- The course “Progettazione in campo dinamico” aims to deepen and apply the theoretical tools of system dynamics, acquired during the studies, to the modeling of the dynamic behavior of systems and simple machine components in the time and frequency domain, addressing Finite Element modeling and simulation techniques.
- Reference texts
- Lecture notes of “Progettazione e Costruzione di Macchine” (Prof. Braccesi)
S. Timoshenko, “Vibration Problems in Engineering”, John Wiley & Sons Inc., March 1990
Matlab and ANSYS manuals - Educational objectives
- The student will acquire the ability to use the theoretical tools of system dynamics, acquired during the studies, to model and dynamically simulate simple systems and components modeled by lumped parameter modeling and by FEM modeling, finalizing it to the evaluation of their stress state in time and frequency domains.
- Prerequisites
- To understand and be able to apply most of the techniques described in the teaching, preliminary knowledge of "Progettazione Meccanica Avanzata" is required.
- Teaching methods
- The module is organized in:
• classroom lectures during which the topics covered in the course are addressed.
• in parallel, classroom exercises will be carried out using MATLAB numerical language and ANSYS FEM code
All the teaching material used during the course is available through the Unistudium platform. - Other information
- Further information is available through the Unistudium page of the course. The teacher is available for consultations at the end of each lesson; consultations with the teacher in person or through the Microsoft Teams platform can also be arranged at other times.
- Learning verification modality
- The exam for the course “Progettazione in campo dinamico” consists of two parts:
• a project work to be delivered/sent one week before the exam.
• an oral exam.
The project work is aimed at verifying the ability to apply the methodologies acquired in class.
The oral exam is aimed at verifying the knowledge of all the topics covered. - Extended program
- Recall of structural dynamics: 1-degree-of-freedom systems, multi-degree-of-freedom systems, modal analysis and modal truncation. Integration of the theory of structural dynamics to the application of constraint displacements and/or accelerations. Recall of dynamic modeling and simulation in the state space (SS): physical systems with one, two and n degrees of freedom (quarter car). SS modeling of systems modeled with a modal approach. Dynamic frequency analysis with PSD approach of MiMo systems. Techniques for obtaining responses expressed in terms of PSD starting from inputs expressed in terms of PSD and from the frequency response function matrix of the physical system or its modal representation. Dynamic modeling and simulation with finite elements (FEM) (Dynamic analysis in time and frequency - frequency response and spectrum analysis) using a commercial calculation code (ANSYS). Construction of the state space representation of a FEM model and dynamic simulation in a numerical calculation environment (MATLAB/PYTHON) in a finite element calculation environment. Use of the results of the dynamic simulation in time and frequency for the recovery of the stress state (internal forces and stress tensor), including multiaxial condition, of the generic point of the generic component: static approach and modal approach Development of a year's work using numerical calculation codes and FEM
