Description of the research topic:
Background:
The finite element analysis and the simulations based on it are of primary importance in the vehicle industry. Various models are built and are used during vehicle development, from the level of unique part to the level of a whole assembled vehicle. The model simulation results are accurate enough only if the numerical model behavior suits well the behavior of the real structures. To reach that, it is necessary to know precisely the parameters of the real structures and to implement them in the numerical model. For this reason, the validation thus the identification of real structure parameters is a very important topic. Data issue from measurements is necessary to the fine tuning of such numerical simulation systems. Our department does have the theoretical background and practical expertise for such measurements.
Goal of the research:
Elaboration of a method allowing verification of numerical model’s precision through measurements of real structures. The method must be suitable to identify parameters such as fixations, material properties, excited vibrations, eigen frequencies, damping, etc.
