✦ Synopsis

To improve the performance of a non-linear shock isolator, four di!erent alternatives are being considered and compared. These are (i) an isolator with a Coulomb damper, (ii) a three-element isolator, (iii) an isolator along with vibration absorber and (iv) a two-stage isolator. Three di!erent types of shock inputs are considered as the base motion to be isolated. Three di!erent indices are used to judge the overall performance characteristics of the isolator. Overall, it is seen that the three-element and two-stage isolators are preferable in the presence of a non-linear cubic damping.

Chaotic oscillations of a harmonically excited mass on a non-linear isolator are investigated. The magnitude of the strictly dissipative damping force on the mass, provided by the isolator, is assumed to be proportional to the pth power of velocity.
