1 ME 240: Introduction to Dynamics and Vibrations Mechanical Engineering Department University of Michigan Fall 2008 Computer Assignment #2 November 26 th 2008 (Due: December 8 th 2008) There are many situations that require the isolation of objects or people from vibrations. In many cases these vibrations can be modeled as base excitations. An example of this is a car traveling on a bumpy road; the suspension is designed to isolate the passengers from the motion induced by the bumpy road while, at the same time, ensuring that the contact between the wheels and the road is maintained. Other examples of the need to isolate a system from vibrations include protecting sensitive measurement equipment (such as atomic force microscopes for nano-scale engineering) from being affected by environmental vibrations. Consider that a sensitive device of mass m is placed on a support which is exposed to environmental vibrations. These vibrations manifest as base excitation with a displacement
