Free shock-absorption calculations

Shock damping is essential in many demanding environments, including naval, military, offshore, transportation and industrial, where sensitive equipment must be protected from shock impacts, heavy impacts and vibrations.

Solving shock and vibration problems requires a thorough understanding of the entire dynamic system, both the impacts the equipment is exposed to and the reactions that the structure gives back. That is why IAC Acoustics offers a free 6DOF calculation, which gives a clear picture of the residual shock in your equipment.

Shock absorbers for different sectors and challenges

Shock absorbers are specially developed components that protect equipment from sudden shocks/impacts and vibrations. They act as an elastic intermediate link between the equipment and the structure on which it is mounted, absorbing the energy so that the equipment is not overloaded.

Shock absorbers are used in many sectors where operational reliability is crucial. In the navy, they protect mechanical and electronic equipment, weapon systems and other critical equipment from shock impacts, the strongest of which are from explosions. In the military, they are used in vehicles, mobile units, bunkers and containers, where the equipment is exposed to both shock, strong vibrations and harsh mechanical impacts. They are also used in industry, offshore and transport to secure equipment such as pumps, generators and communication systems against shock and vibration during transport or installation.

Here are examples of the use of shock absorbers in the navy

Shock calculation with simulation of response

Solving shock and vibration problems requires that all inputs (shocks, vibrations, movements) and reactions (equipment, construction, suspension) are analyzed. We offer a free 6DOF calculation, and once the calculation is complete, you will receive a report with the results for the size of the residual shock. This gives you a basis for assessing whether the equipment can withstand residual shock and whether the design or dampers need to be adjusted. The calculation can also be used as documentation to the end user that the solution works.

Knowledge and process make the difference

Achieving effective shock damping requires both technical expertise and a proven, structured approach. The global method, developed by Socitec Group and used by IAC Acoustics, is based on advanced design and simulation tools and is anchored in ISO 9001 procedures.

The process may include various elements listed below:

• Establishment of shock and vibration requirements
• Preliminary studies
• Analysis and simulation of the structural response
• Selection of the most suitable technology, mounting direction and standard or custom model
• Final simulation of the proposed solution
• Verification through prototype testing
• Qualification testing according to commercial and military standards
• Validation of the solution with advanced measuring instruments

At the technical level, IAC Acoustics offers, among others:

• Mechanical design in SolidWorks (custom solutions, equipment racks, resilient floors).
• Static and dynamic FEM (Finite Element Analysis) analysis in ANSYS of structures (e.g. containers, cabinets, transport systems).
• Numerical simulation in SYMOS of nonlinear mechanical systems subjected to shock and vibration input
• Drop/shock tests, vibration tests, fatigue tests and experimental modal analysis

This holistic approach ensures that solutions not only work in theory, but also deliver stable performance in reality, including in marine and military environments, where the requirements are particularly high.

Why should you choose IAC Acoustics?

IAC Acoustics has over 60 years of experience in shock and vibration damping and works with proven technologies used in naval, military, offshore and industrial applications.
