Simple linear springs in suspension systems are used in many applications to reduce transmission of vibrations. But, since the natural frequency of the suspended component is dependent on its mass, detuning the system away from resonance is a major design problem. An adjustment of the suspension spring may be required for any given mass. A solution to this problem is to employ a nonlinear universal spring which causes the static equilibrium position to be shifted when the suspended mass is changed. Thus, the stiffness changes in such a way that the natural frequency stays constant in a broad range of mass variations. In this project theoretical analysis, design, construction, and testing of a nonlinear "universal" spring was accomplished.
