2022-04497 - Research internship - Exploring waveguiding phenomena for ropeway transport

Contract type : Internship agreement

Level of qualifications required : Master's or equivalent

Fonction : Internship Research


Background : Noise Vibration & Harshness (NVH) are a major industrial and scientific issue due to their economic, technological and ecological implications. In the transport sector, which is particularly affected and where safety and comfort are essential criteria, many technologies have the sole objective of controlling the transmission of noise and vibrations, which can take place by ground-borne or air-borne means. In ropeway transport (e.g. cable cars), the main source of vibration transmission is caused by the propagation of elastic waves in the cables. The consequences are significant in terms of comfort in the cabins, surrounding noise, then in terms of wear and tear on the infrastructure. The transmission mechanisms of these vibrations are still not well understood, due to the wave nature of the phenomena and the complexity of the associated dynamic models.

Description of the internship : This internship will take place within the I4S team of the Inria center at the University of Rennes. In particular, we are developing ultra-fast numerical methods to predict the wave and vibro- acoustic response of structures with complex geometry (composites, periodics, multi-scale, etc.). The applications cover the fields of guided wave inspection, the design of metamaterials and their vibro-acoustic optimization. These tools have already led to the discovery of several remarkable phenomena in waveguides and periodic structures. The internship, in collaboration with the company POMA, will aim to apply a numerical method for the analysis of the wave and dynamic response of a cable transport system. Experimental data will be collected in order to establish a relevant substructure finite element model in mid-frequency dynamics. These digital models will provide an unprecedented perspective on the underlying physics and will allow the creation of new indicators of design, optimization and vibration control. PhD opportunities can be considered at the end of the internship.

Keywords : Computational Mechanics or Acoustics, Waves, Civil Engineering, Cable Modelling, Finite Element Method.
