This work includes the development of a vibration model of spider webs and its implemen-tation in the commercial Finit element software ANSYS Workbench 15. The current state of the art of the system spider web will contribute to the model as well as the knowledge of material properties. An overview of the recent level of education concerning the particular characteristics of spider silk and the web will be followed by the mathematical foundati-ons of the modeling. During the further course the work deals with the establishment and explanation of the material and vibration model as well as the investigated geometry of the web. This will be followed by the implementation in ANSYS. For implementation and analysis, boundary conditions by literature are compiled and assumptions are taken. This will be followed by a validation of the Finit element model with previous measurements. Using the software LTSPICE and utilizing electrical analogies, missing parameters were de-termined and implemented in ANSYS. The comparison with the measurement results shows a very good agreement of the Finit element model. By means of parametric studies, the influences of various quantities on the oscillation frequency of a symmetrical web geometry are detected and quantified. Subsequently, an asymmetric web and the effect of different excitation points on the waveform are investigated. Result of this work is a robust and for further investigations applicable Finit element model. Related suggestions are provided in the outlook. Furthermore, other interesting questions for future research are mentioned.
