This series covers the fundamentals of torsional vibrations, including the derivation of equations of motion and the use of Python for modeling and analysis. The application is specific to gearbox testing bench setups.

Introduction

The subject of torsional vibrations is crucial in the design and analysis of rotating machinery, particularly in applications such as gearboxes. This stems from the fact that the rotating components in these systems (e.g., shafts) transmit power under twisting conditions due to their finite stiffness; thus, variations in the transmitted power may lead to torsional vibrations given by the coiling-uncoiling behavior of the shafts. In this series, the aim is to provide a comprehensive overview of torsional vibrations, including the derivation of equations of motion and the use of Python for modeling and analysis. Along the way, we will build our own solver for the equations of motion, which will allow us to simulate the system’s response under various conditions and to gain insights into the dynamics of torsional vibrations in the context of gearbox testing bench setups.

Outline

In this third and final part of this tutorial series, you will learn how to use PyGRITbx to:

1. perform gear tooth bending analysis
2. perform gear tooth pitting analysis
3. perform bearing life analysis

These analyses are based on the forces calculated in Part 1 of this tutorial series. Therefore, make sure the code blocks from that part are present in a currently active Jupyter session and have already been executed before you try to run any of the code blocks in this part.

Outline

Hello and welcome to the second part of this tutorial series. In the previous part, we learnt how to:

1. install PyGRITbx along with the tools required to work with it
2. define components that constitute a given gearbox
3. define interactions between components
4. calculate the forces exchanged between said components and the reaction forces produced by the bearings.

In this part, we will take the results from Part 1 to:

This blog post is the first part of a 3-part series. In this series, I would like to introduce you to my python toolbox with a tutorial based on a project given to mechanical engineering students following the course “02SXJJM - Fundamentals of Machine Design” at Politecnico di Torino. My best hope is that this series would serve as a guide for the reader in future projects concerning geargbox design validation. The complete code for this tutorial can be found here.

Welcome To My Website

Hello and welcome to my website.

I will attempt to share my thoughts with the interested reader using blog posts. Topics will vary in discipline but mainly I would like to portray my perspective on the following:

• Mechanical Engineering
• Programming Tutorial for Engineers
• Books and Recommendations
• Music
• Religion
• Who knows what(?)

Please note that I will try my best to backup my thoughts and ideas with references that would lead the reader to the source. However, everything I share is based on my humble knowledge and experience on the subject matter and mistakes are to be expected.
