The course aims to explore simulation techniques for the dynamic behaviour of automotive powertrains, with particular emphasis on the new challenges introduced by their progressive electrification. Different modelling methodologies, available in the commercial AVL Excite software, will be illustrated depending on the product development phase, ranging from 3D models to equivalent 1D torsional models. Examples of industrial applications concerning the vibro-acoustic behaviour of thermal, hybrid and electrically powered vehicles will be shown. Below are the details of the individual lectures: Lecture1 (4h): - Introduction - Engineering tasks in simulation of dynamics and NVH of ICE (Internal Combustion Engine), HEV (Hybrid Electric Vehicles) and BEV (Battery Electric Vehicles) powertrains - Dynamic models of crankshaft, other ICE parts, and parts of BEV powertrains Lecture2 (4h): - 3D dynamic analysis of ICE and BEV powertrains in time and frequency domains Lecture3 (4h): - Dynamic analysis of engine mounts in ICE and BEV powertrains - Assessment (multiple choice questionnaire) - Final remarks LEARNING OBJECTIVES / QUALIFICATIONS OBTAINED - Demonstrate awareness of the main problems arising during design / troubleshooting of different powertrain types and engineering tasks aiming at resolving them. - Knowing the two main phases of the powertrain dynamics calculation project with corresponding modelling depth and related levels of simulation tools applied. - Understanding the difference between condensed and structured dynamic models of engine/powertrain parts, including the awareness of the procedures of their generation. - Understanding the theory and workflow to generate structured dynamic models. - Understanding the universal methodology to evaluate and verify the dynamic properties of models using a) modal analysis; b) full dynamic forced response. - Understanding the differences in calculation targets and methodology, as well as in modeling depth between simulation in time and frequency domain. - Understanding the theory and methodology of 3D dynamic and vibration analysis of ICE and BEV powertrains. - Understanding the theory and methodology of torsional vibration analysis of ICE and BEV powertrains. - Understanding the theory and methodology of 3D dynamics of low-frequency NVH of mounted engine/powertrain.
