1. Project Title

Innovative contact-based multibody model for noise and vibration prediction in high performance gears
PRIN  2020
Period: 25/04/2022 – 24/04/2025

2. Project Description

The project aims to develop innovative models and tools to improve the design of high-performance gears, increasing efficiency and reducing vibration and noise. Based on flexible multibody models and optimization techniques, it integrates dynamic analysis and experimentation to create a comprehensive and predictive simulation environment.

3. Project Objectives

  • Develop a multibody model based on the pseudo-rigid body method for three-dimensional modeling of tooth contact in gear transmissions.
  • Develop a new multibody model based on the modal approach.
  • Integrate an epistemic uncertainty model to analyze the effects of operating parameter variability on the dynamics of high-performance gears.
  • Develop an acoustic model capable of translating vibrational results into equivalent acoustic power, mapping the rigid and flexible motion of gear surfaces.
  • Experimentally validate the proposed models, comparing numerical results with laboratory tests and defining benchmarks useful for performance evaluation.
