Shock isolation using switchable stiffness
… control strategy applied to the problem of shock isolation. This is based on the principle that the stiffness and mass are the principal physical properties that control the passive system shock response. The problem of shock response control is divided in two stages. Firstly, the maximum …

Carbon fiber substitution in shipboard instrument structural mounts for vibration and shock isolation
Insufficient support and isolation of rotating and non-rotating shipboard equipment and instruments may cause damage to the components or the ship itself. Reduction of noise emissions to the ship's hull and protection of equipment from outside disturbances may be attained through isolator mounting …

Mechanical Shock Analysis and Testing of an Air-Dropped Antarctic Ice Penetrator
… can damage the delicate seismometer. SGIP uses shock isolation to reduce the seismometer's peak acceleration. A structural response model is used to predict the seismometer's dynamic response to ice shelf impacts with hundreds of potential shock isolation designs. This structural response model …

Application of Nonlinear Localization to Engineering Structures
… will find application in robust vibration and shock isolation designs of practical large-scale structures.

Composite materials in dynamic shipboard structural mounts
… composite material. The two types of padding or isolation materials are represented by steel and CFRP (carbon fiber reinforced polymer). Machinery and instruments in ships are often mounted for two main reasons: they create unwanted vibrations and they need to be isolated from shock and external …

Dynamic Analysis of CubeSat Impact on Lunar Surface
… EagleCam. The analyses performed are kinematic shock analysis, vibration analysis, NASTRAN simulation, LS-DYNA simulation and a full scale drop test. The outcomes from this work are that the structure of EagleCam will survive the impact given that the shock isolation system chosen will mitigate …

Combined Shock and Vibration Isolation Through the Self-Powered, Semi-Active Control of a Magnetorheological Damper in Parallel with an Air Spring
Combining shock and vibration isolation into a single isolation system package is explored through the use of an air spring in parallel with a controlled magnetorheological fluid damper. The benefits of combining shock and vibration isolation into a single package is discussed. Modeling and control …
