SHOXSDUAL2 - Semi-Active Shock Mitigation Systems

THE WORLD’S FIRST SEMI-ACTIVE MITIGATION SYSTEM IN ACTION

SHOXSDUAL2 is a shock mitigation system which utilizes real Semi-active suspension technology. Ride conditions are analyzed 1000 times per second and the seat’s time response to damping adjustments happens in as fast as 5 milliseconds. Continuously variable, the SHOXSDUAL2 semi-active mitigation system automatically compensates for occupant weight and automatically modifies the seat response to each and every wave, providing operators with the safest, smoothest ride.

SHOXSDUAL2 is the world’s first semi-active seat mitigation system in use, producing real results. Unlike manual damping adjustments which can increase the probability of injury, SHOXSDUAL2 automatically adjusts damping ratios to maximize shock attenuation for any occupant weight and impact severity. SHOXSDUAL2 does not compromise, giving operators the confidence to perform their duties in dangerous and unpredictable conditions more effectively and safely than ever before.

Analyzing Conditions
At a rate of 1000 times per second

FOR THE SAFEST, SMOOTHEST RIDE AND LOWEST CUMULATIVE SHOCK STRESS

SHOXSDUAL2 is a shock mitigation system which utilizes real semi-active suspension technology. Semi-active suspensions, in response to a wave profile or road surface condition adjust isolator parameters to control seat or wheel movement with an onboard computer. Conversely with passive suspensions these parameters are fixed.

SHOXSDUAL2 uses a solenoid actuated valve to alter the flow of hydraulic fluid inside the damper, therefore changing the damping characteristics of the suspension. The solenoid is wired to an ECU which sends it commands depending on a control algorithm.
No other system utilizes real semi-active suspension technology. Ride conditions are sampled 1000 times per second. Damping ratios are precisely adjusted throughout the suspension stroke, making up to 200 changes per second.
Unlike passive dampers, SHOXSDUAL2 semi-active dampers are computer controlled and are the dominant element in attenuating shocks. This allows for uniquely soft spring rates which accommodate lighter occupants and enhances vibration damping while also providing un-matched bottoming protection for heavier occupants.
SHOXSDUAL2 does not compromise. SHOXSDUAL2 is the world’s first and only commercially available Semi-active seat mitigation system now in use, producing real results, providing operators with the safest, smoothest ride. Unlike manual damping adjustments which can increase the probability of injury, SHOXSDUAL2 automatically adjusts damping ratios to maximize shock attenuation for any occupant weight; any impact severity.

GLOBAL
STANDARDS

ISO 2631-5

ISO 2631-5 addresses exposure to vibration and multiple shocks when a person is seated. The adverse health effects of prolonged exposure is analyzed, particularly in cases where injuries in the lumbar spine are concerned. The calculation of the lumbar spine response assumes that the person is seated in an upright position and does not voluntarily rise from the seat during the exposure.

BIOMECHANICS

Boats operating in the open ocean are subject to large shock and vibration forces. Exposure to such forces can lead to discomfort, spinal injuries and performance degradation, especially when exposed to forces in the vertical axis. SHOXS seats are specifically designed and engineered to reduce the risk of operator injury and impact exposure in harsh marine conditions.

MARINE TECHNOLOGY REPORT

Procedures for Hydrodynamic Evaluation of Planing Hulls

Recent Davidson Laboratory basic studies of planing hull hydrodynamics have produced a wealth of technology which is not generally available to the small-boat design profession. Included are studies related to the preplaning resistance of transform-stern hulls, the effectiveness of trim control flaps, the effect of bottom warp on planing efficiency, the influence of reentrant transform forms, and the seakeeping of planing hulls.

The present paper consolidates these results in a form suitable for design purposes and illustrates their application in predicting planing performance in smooth and rough water.

PROPOSAL TO INDUSTRY

Industry Standard Seat Performance Evaluation Criteria

As a service to our community, we are committed to helping our clients by developing the tools they need to make informed decisions in selecting the seating solutions that best fit their application.

Industry Standard Seat Performance Evaluation Criteria (ISSPEC) is CDG’s industry leading vision to facilitate industry collaboration by creating the framework of an unbiased, scientifically valid and economical laboratory performance testing method of shock mitigating seats.

ISSPEC is not meant to replace existing field testing methods– rather it is an economical, repeatable, simple and useable means to evaluate, compare and categorize shock mitigating seat performance in the early stages of design and procurement processes.

INDEPENDENT STUDY

NAVAL HEALTH RESEARCH CENTER

Participants were SBU operational personnel, drawn from SBU-12, SBU-20 and SBU-22. One hundred and fifty four SBU personnel participated in this study. They all had the Special Boat Naval Enlistment; Codes: (NEC) 5350 (Special Warfare Combatant Crewman [SWCC] basic), 5351 (SWCC Intermediate), or 5352 (SWCC advanced).

ARTICLE

SHOCK MITIGATION DIRECTORY

Extreme high speed craft are constantly evolving as counter-terrorism and enforcement roles change in the military, coast guard and police sector. The professional sector needs a shock mitigation strategy or crews will not be capable of doing their job when they arrive at their destination. The definition of shock mitigation is, 'to make a violent collision or impact less intense'. With an effective shock mitigation strategy the helmsman, crew and passengers benefit from increased comfort and reduced injury while the organization has increased operational efficiency.

SCIENTIFIC PAPER

VIRGINIA POLYTECHNIC INSTITUTE AND STATE UNIVERSITY

SHOXS competitors utilize passive suspension systems, not true semi-active mitigation systems. SHOXSDUAL2 is the world’s first true semi-active seat mitigation system in use. This independent study provides an in-depth look at the disadvantages of passive suspension systems as well as important conclusions for why true semi-active suspension systems mark a significant improvement on older passive system technology.

SHOXS Help Keep Agents Safe as they Eliminate Threats in Rough Waters

Docked in one of four slips that Customs and Border Protection leases at the Port of Port Angeles' Boat Haven is the 38-foot version of the Interceptor. It's called a Secure-Around-Flotation-Equipped boat, and it's made to be unsinkable. It sports four, 300-horsepower engines, each with its own throttle. The paramilitary speedboat is capable of cruising at 60 mph. A foam collar wrapped around the hull helps absorb the shock that's inevitable — even on placid waters — along with expertly constructed SHOXS seats that accordion slightly with every bounce, and seat arm-rests...
