LEDEZMA-RAMIREZ, D. F.; FERGUSON, N.  e  BRENNAN, M.. Shock Performance of Different Semiactive Damping Strategies. J. appl. res. technol [online]. 2010, vol.8, n.2, pp.249-257. ISSN 2448-6736.

The problem of shock generated vibration is presented and analyzed. The fundamental background is explained based on the analysis of a single degree-of-freedom model with passive stiffness and damping. The advantages and limitations of such a shock mount are discussed. Afterwards, different semi-active strategies involving variable damping are presented. These strategies have been used for harmonic excitation but it is not clear how they will perform during a shock. This paper analyzes the different variable damping schemes already used for harmonic vibration in order to find any potential advantages or issues for theoretical shock pulses.
