Validate mechanical behavior of 3D bolt connections

Backgroud:

A bolt connection is a default connection between at least 2 parts of a construction. Most of the times the connections in the construction are over-dimensioned. In these cases, the mechanical behaviour of the construction depends on the behaviour of the parts and not on the behavior of the connections. However this is not in each situation possible. If the connection itself has a large influence on the mechanical behaviour of the construction than this should be known by the designer. The behaviour of the construction can be analysed by using Finite Element Method (FEM) but then also some knowledge about the connection is needed. Carry out measurements on a test construction were the bolt connection is determined for the overall behavior helps to get more insight in the behavior of the connection.

Purpose:

The aim of this project is to study and validate the stiffness of a 3D bolt connection by comparing the results of dynamic measurements with comparable FEM results. Translate the results in design tools which can be used by the designer/engineer.

Outline:

The activities to execute are:

Study theory of a bolt connection
Design a test construction
Carry out the dynamic measurements for several situations
Analyze the test construction by using FEM and compare the results
Develop design tools to predict the mechanical behaviour of several types of bolt connections

Preferably you study a bachelor or master in Mechanical Engineering. The actual content of the project can be adjusted to your level. Knowledge of constructions, dynamics and FEM (Ansys) is preferred.

Type of project:

Traineeship, bachelor level or graduation, master level.
