OpenTorsion: Python library for torsional vibration analysis

Torsional vibration analysis is a crucial part of rotordynamic analyses during powertrain design for various industry applications. The torsional analysis is typically performed using specialized codes to model and simulate the system dynamics, with the goal of computing the torsional stresses to optimize performance and prevent failures. This paper presents OpenTorsion, a Python library for conducting torsional vibration analysis. The library enables the modeling of torsional dynamics across a wide range of applications, including vehicles, maritime systems, and energy production. As methods for torsional vibration modeling continue to evolve, an openly developed and freely distributed open-source library such as OpenTorsion provides an excellent platform for systematic dissemination and sharing of new research developments.
