Özet:In the design stage of a mechanical structure, the effects of vibration are taken into consideration as important design criteria. In order to eliminate the adverse effects of vibration sources, a direct intervention to the vibration source, structural reinforcement or the use of vibration isolators are encountered as the most popular vibration control methods. Among all, being compact, low cost, reliable and maintenance free, elastomeric passive vibration isolators with linear properties are examined within the scope of the present thesis study. In this thesis, the mechanical structure mounted on elastomeric resilient elements is modeled theoretically. In this theoretical model, the mechanical structure is assumed to be a rigid body with 6 degrees of freedom. Having obtained system matrices and input vibration profile, modal analysis, static deflection analysis in addition to response analysis for harmonic and random type of excitations are made available in software developed. Additionally, in order to design an efficient vibration isolation system, both location and parameter optimization of elastomeric isolators are included in the present study. In comparison to similar studies in the literature, types of analysis, in addition to the optimization design variables are improved so that a more flexible design environment is introduced. For practical design purposes, a graphical user interface is also included. Using the developed software, a designer will be able to analyze an isolation system and optimize design variables considering various types of optimization problem scenarios.
