Combined Shock and Vibration Isolation Mounts Incorporating Novel Shock Dissipation Mechanisms

"A critical need exists for improved shock mounts to assure that equipment being developed under the Navy's Advanced Damage Countermeasures (ADC) program are well isolated and shock tolerant. These mounts must minimize shock transmission during extremecatastrophic events while retaining excellent vibration isolation characteristics under normal conditions of operation. Heretofore it has been impossible to optimize performance for both of these requirements in a single isolator component. To addressthis problem, the innovation proposed by Creare is a highly effective vibration isolator that incorporates a set of novel shock dissipation mechanisms. The primary benefits of Creare's design are that it combines shock mitigation and vibration isolationin a single mount and has the potential to greatly reduce shock loads experienced by critical ADC systems. In addition, the mounts will be highly durable and resistant to environmental effects, be straightforward to install in new or retrogradeapplications, require no maintenance and exhibit low life-cycle cost. We will demonstrate the feasibility of our innovation during Phase I with laboratory proof-of-concept tests. During Phase II, we will fabricate and test prototype units at Creare andprovide several prototype units for a selected ADC equipment application to the Navy for ship trials. The proposed mount concept is capable of providing shock and vibration isolation for critical equ
