| Abstract: | Many modern systems, especially high precision mechanisms are equipped with a vibration isolator. Vibration isolators remove undesired vibrations from a system or reduce their amplitude as much as possible which improves the performance of the systems. These absorbers consist normally of a flexible support, for example a compression spring, while this research is focused on a different way to construct these vibration isolators. Magnets are used instead of springs and therefore a magnetic levitation system is achieved. A magnetic levitation system is based on the ‘quasi-zero stiffness’ principle and can be achieved by adding a positive stiffness to a negative stiffness which results in a lower natural frequency. In this research, the aim is to elaborate the theory and compare the experimental analysis to simulations. To do so, a new LABVIEW-program is written to communicate with the magnetic levitation system. Occurring errors are discussed as well as the influence of all the LABVIEW-components on the results. Magnets are measured and a curve fit is made to ensure the experiments are equal to the simulations. At last, transmissibility experiments were carried out and conclusions were drawn on the usefulness of this device. |
