Dimensioning and designing a testing rig for impact loading on beams : .

University essay from Linnéuniversitetet/Institutionen för teknik, TEK

Abstract: This report is product of a degree project accomplishment at Linnaeus University in Växjö, Sweden. It is about designing a testing rig for impact loading of beams for laboratory use. The specimens to be used were 1 meter long 8 standard profiles given in the project assignment. The first step in this project was to design and dimension a testing rig which is suitable for laboratory use. The height and the maximum mass were chosen according to laboratory use conditions and safety issues. The second step was designing the fixation for the test sample to the testing rig without any dislocation by the impact load. The third step was to measure the falling height of the mass onto the test sample and measure the deflection of the beam. In this case, the precision of falling height was not very important but measuring the deflection of the beam with the highest possible precision was most important. A measurement system is used considering this factor. The project started with the idea of affecting the impact loads on the standard steel construction beams. The aim of this project is to design an impact loading testing rig which can be used for the purpose of laboratory experiments and compare the real results from the experiments with the theoretical results from the calculations. In the project, Solid Works and AutoCAD software are often used both in the drawings and strength and stress analyses.
