Detailed Powertrain Dynamics Modeling in Dymola – Modelica

This document explores the development and application of Modelica-based Powertrain Dynamics and Engines libraries within Dymola for detailed automotive powertrain simulation. The research focuses on modelling engine, transmission, driveline, and torque converter dynamics to study vehicle behaviours during transient driving events such as vehicle launch, tip-in, tip-out, gear shifting, and vibration analysis.

By integrating dynamic torque converter models and crank-angle resolved engine simulations, the study demonstrates improved prediction of drivability, torque pulsations, vehicle response, and overall powertrain performance compared to traditional steady-state approaches, highlighting the benefits of high-fidelity simulation for vehicle design, optimisation, and control strategy development.
