Students participate in project groups, including a researcher at the department as the supervisor. A few project examples are described briefly below.
Static Characteristics of Flexible Bellows
(by Madeleine Hermann and Anders Jönsson)
Flexible metal bellows.
This was a study of the characteristics of gas-tight flexible metal bellows that are used, for example, between the engine and the catalytic converter in automotive exhaust systems. Analytical analysis, finite element analysis, and experimental analysis were used. The work was done in collaboration with Faurecia Exhaust Systems, a company that supplies Ford/Volvo, VW, Jaguar, and many other car industries with exhaust system components. Madeleine and Anders became PhD-students at Blekinge Institute of Technology.
Dynamic Behaviour of a Soil Compaction Tamping Machine
(by Jens Borg and Anders Engström)
Soil compaction tamping machine.
This was a study of a soil compactor machine. The machine was modelled as a system of masses, springs, and dampers and described by a system of non-linear differential equations. The solution of these equations describes the motion of the machine. A computer program was developed to solve the system of equations. Experimental studies of a real machine was done and these experimental results were compared to the theoretically predicted results. The work was done in collaboration with Dynapac. Jens became a prediction expert at Bombardier and Anders a prediction expert at Dynapac.
Design and Dynamic Analysis of a Space Frame for Acoustic Measurements
(by Tommi Paananen)
Car body to be resembled by a spaceframe.
This was a study of the characteristics of a so-called space frame, which will resemble the skeleton of a car body. The structure is used to test how different floor plates radiate noise. A modal analysis was performed both by the finite element method and experimentally. The work was done in collaboration with Chalmers University of Technology, Volvo, Saab, and Collins & Aikman. Tommi became a prediction expert at ABB Robotics.
