AVL is the world's largest independent company for development of powertrains (combustion engines, hybrid systems, electric drive) as well as simulation and test systems for passenger cars, trucks and marine engines.

We offer a master thesis:

Sensitivity analysis valvetrain clearances on NVH of an I.C.Engine

The vehicles are getting quitter and quitter every year. Vlavetrain is one of the main NVH sources as mechanical source. However the engines as hardware has very different tolerances and clearances. This thesis wants to study the sensitivity analysis of the valvetrain parts. This will create a know how that what variance in radiated sound can be expected from

Task:

  • Literature study
  • Parametrization of the valve train model
  • Study the valvetrain multibody dynamic model
  • Forced response for NVH, and sensitivity analysis on NVH
  • Comparison of the cases and design for recommendations and guideline for simulation

Study:

  • Mechanical engineering, Technical physics

Requirements:

  • Experience in Dynamic and vibration
  • Language: English or German

Remuneration: The successful completion of the thesis is a one-time fee of EUR 2.500, - gross remuneration
