What are the effects of shock and vibration?
Excessive amounts of shock and vibration can cause equipment to malfunction and systems to fail. In some cases, such as the collapse of a bridge or a building, the results can be catastrophic. Shock and vibration aren’t just problems for architects, however. Designers of vehicles and equipment also need solutions to vibration control ...
Is shock a one time event?
Whereas vibrations are repetitive, shock is generally a one-time event. Yet that doesn’t make mechanical shock any less serious. If a tractor or military transport lacks shock absorbers, the vehicle will bounce excessively. This can cause onboard electronics to malfunction and personnel to sustain injuries.
Can vibration isolators help?
Vibration isolators can help , but excessive vibration may not be the only design challenge you face. For applications such as mobile equipment and military vehicles, engineers also need to account for shock – a sudden impact that produces mechanical stress.
What is the purpose of shock absorption material?
To be effective, a shock absorption material must have the capacity to eliminate or reduce oscillations across a wide range of frequencies. To be effective in an industrial environment, a shock absorption material must perform well in a wide range of temperatures, even changing temperatures, regardless of the source of the shock, ...
How does shock energy absorb?
How Is Shock Energy Absorbed? A process called damping —the dispersion or disruption of the energy caused by shock’s impact forces—absorbs the energy from shock by decreasing the amplitude (strength) of the shock energy’s wave or by changing the wave’s frequency.
Why is shock important?
Because shock is usually associated with adverse effects to objects or individuals, it will ultimately cause inefficiencies, such as waste, rework, and downtime. Shock absorption, therefore, increases the lifespan and/or the safe operation of the application.
What is shock in science?
What is shock? Shock is the effect on an object caused by the energy delivered to it by a force, usually an impact force, over a short time period. The effect of shock occurs when the energy of the impact is transferred from one individual or object to another.

What happens when you hit a shocktec gel?
When a force hits SHOCKtec Gel or Air2Gel, the impact is immediately dissipated throughout the entire pad. The force is spread out across a larger area with a minimal amount hitting directly under the impact area.
Does shocktec compress?
Over and over again. Because SHOCKtec never fully compresses, the object striking the padding will never make contact with the object being protected. Read more. The ability of our padding to return to its original shape immediately after deformation is second to none.
Does shocktec foam last longer?
SHOCKtec has greater shear-strength than comparable foams that typically breakdown rapidly and lose material effectiveness. No other padding will last longer and still do its job. Unlike traditional gel products, ours has a load-carrying ability second to none, and is even used to support heavy industrial machines.
Does Shocktec padding feel good?
No other padding feels as good against the skin. SHOCKtec properties prevent friction between the padding and human skin. Read more. This helps prevent damage to tissue and nerves that cause blisters or sores. Our product distributes weight evenly, is not a stiff material, and dampens vibration resulting in greater cushioning and comfort.
Is Shocktec Air2Gel lighter than gel?
SHOCKtec Air2Gel is 80% lighter than typical gel padding. SHOCKtec is lighter than most comparable gels and foams of similar size and density. Each of the products conforms easily to ones body allowing for freedom of movement that is far superior to common padding products.
