Our team has worked on some of the most extreme noise, acoustic, vibration, and shock-mitigation problems. We have developed solutions for marine vehicles (submarines and surface ships), ground vehicles (Humvees), airborne vehicles (helicopters and aircraft), space applications (orbital satellites and launch vehicles), and facilities (hospitals and health care centers).

We have experience designing airdrop systems for efficiency and reuse, gun mounts to protect electronics aboard helicopters, improved air filters for ground vehicles that optimize receiving vibrations, enclosures and mounts to keep shipboard electronics safe and working after blasts, and components for critical command-and-control vehicles, to name a few.

SHOCK-Honeycomb

By using our system that includes reusable materials, the military saves time, money, and resources.

Solutions for Aerial Delivery

Military personnel require aerial delivery systems that are lightweight, modular, and reusable. The current wood platforms are susceptible to the environment, are heavy, and are often destroyed after a single drop. The ShockTech AE-R&D solution includes replacement of cardboard honeycomb with our reusable SHOCK-Honeycomb, and redesigned platforms that are modular and environmentally resistant.

Our SHOCK-Honeycomb product was used to replace current cardboard honeycomb. Made from Shock Tech’s proprietary elastomer with a 99% energy-absorption rate, this highly shock-absorbent material is durable, resistant to moisture, and reusable.

Shock Tech AE-R&D developed a unique, modular platform that incorporates composite materials, shock isolators, and topological optimization. Features include weather resistance, ease in assembly, improved energy-impact dissipation, reusability, and modular architecture to accommodate load changes.

MULTIPLE PROTOTYPES WERE MANUFACTURED AND TESTED

Effective Enclosure

Our solution allows for fast, cost-saving equipment upgrades.

Multi-Stage Structurally Integrated Isolators

For naval ships to upgrade mission-critical hardware, current electronic enclosures need to be more effectively protected against excessive vibration and shock loads.  Such isolators should not need to be reconfigured, requalified, and redesigned as electronic technologies change.  The Navy needed the ability to swap hardware without requalifying isolators protecting electronic enclosures.

Shock Tech’s Multi-Stage Structurally Integrated Isolators with Upgradeable Adaptable Capabilities is an innovative solution for naval ships.

Our design protects critical shipboard equipment and allows for fast, easy component replacement and upgrades—putting an end to costly and time-consuming requalification of isolators protecting enclosures. The use of prototyping, computer simulation, and component fabrication has demonstrated conclusive results during testing.

 

Low-Frequency Noise

Testing found dangerous levels of noise. We prescribed a safe, cost-effective solution.

St. Luke’s Hospital Fan-Vibration Damping

Staff at St. Luke’s Hospital in Duluth, Minnesota, began experiencing physical discomfort from noise and vibration in their work environment after exhaust fans were installed on the roof.

Shock Tech AE-R&D collected data on site and discovered low-frequency noise in the range of 60 to 70 Hz. In general, it is low-frequency (below 100 Hz) noise that can cause physical harm to people.

We recommended an elastomeric isolation system to dampen the vibration. The system can be customized for maximum mitigation of transmission of low-frequency vibration to the roof. Shock Tech’s AE-R&D solution is less costly and more sensible than moving the fans to another building, as was suggested by construction engineers.

Eight ShockTech elastomeric isolators were installed between the fans and the roof. As a result, the noise level in the effected room was reduced in the range of 4 to 12 dBA, up to 19 dBC. In terms of vibration reduction across isolators, up to 98% vibration reduction was achieved. These reductions were considered noteworthy.
