ABSTRACT
The problem of shock generated vibration is presented and analyzed. The fundamental background is explained based on the analysis of a single degreeoffreedom model with passive stiffness and damping. The advantages and limitations of such a shock mount are discussed. Afterwards, different semiactive 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.
Keywords: Damping, shock, vibration.
RESUMEN
En este artículo se presenta y analiza el problema de vibraciones generadas por impacto, basado en la respuesta de impacto teórica de un sistema de un grado de libertad con rigidez y amortiguamiento pasivos. Se discuten las ventajas y limitaciones de esta configuración. Posteriormente se estudian diferentes estrategias de amortiguamiento variable que han sido usadas en vibración harmonica pero no es claro como se comportarán bajo impacto. Este artículo analiza estas estrategias para encontrar cualquier posible ventaja o problema cuando se usan en situaciones de impacto.
