Master's thesis of Mechanical Engineering: Analysis of a vibration isolator with dual rate spring and damper

In the course of current research the procedure of obtaining of the piecewise linear vibration systems time and frequency responses have been developed. The method is partly analytical and partly numerical and is based on combining of linear solutions of different sections in a cycle of motion. In a row with the method of obtaining of the exact steady state time and frequency response, also it is provided sensitivity analysis of the vibration isolator. Numerical challenges that were raised during the modeling of the system’s frequency response and possible solutions of them have been considered. In addition, different normalizations of the model of the system are reviewed and their impact on the results is discussed.
