Spring isolators systems are commonly used in a variety of ways in today’s construction industry. They are an essential part of the design of many mechanical systems that are in need of absorbing and dissipating unwanted vibrations. In the construction industry, vibration isolation systems have been installed without completely understanding how these systems are selected. The goal of this paper is to create a tool that will make the selection process easier for designers and installers. A Matlab© [1, 4] computer program will be created to give graphical models of the steady state vibrating motion of an Air Handling Unit (AHU) with a selected vibration isolation system. The program will be able to simulate any model with the phenomena of a vibrating rigid body on a resilient supported element which will be caused by a vibratory force, or moment, that is generated within the body, creating unbalance. This program will also be able to calculate the natural frequencies of the mode in order to make sure that it will not cause the model to fall under the unwanted effect of resonance that will eventually cause our model and its supports to fail. Key Terms - Isolators, Natural Frequency, Resonance, Vibration Isolation.
