DEFENSE
Mine Blast Attenuating Seat
Design & Evaluation
· Provide design solutions suitable for the space of the target vehicle
· Quality assurance based on national defense standards and overseas standards for MINE BLAST ATTENUATING SEAT assembly and component levels
DESIGN SOLUTION(CUSTOM DESIGN)
Protect the crew from the effects of landmine and improvised explosive device (IED) blasts
Designed to structurally dissipate the shock of the blast on the vehicle’s body
Damping device (GAS spring) applied, front/rear/up/down height adjustment function
Emergency escape function (driver seat), footrest applied (crew seat)
Variable headrest design (designed according to the use and size of the crew helmet)
T-shaped support, U-shaped support, footrest, and armrest
Custom design according to requirements such as vehicle functions and characteristics (change shape and mounting location, add additional devices, etc.)
Seat belt selection application (4-point or 5-point type)
Provide design solutions suitable for the space of the target vehicle
Prioritize the review of blast attenuation requirements
Considering the severity of blasts for condition 𝒗 and selecting the design according to the requirements
Material selection within the tested range: re-evaluate materials using blast attenuation materials and principles and structural interactions
Selection of energy-absorbing materials that maximize blast energy absorption through elastic and plastic changes
Modeling according to customer requirements
Verification using LS-DYNA blast prediction and analysis software
CAD model design, meshing, and material property verification for real mechanism and model simulation representation
Conducting proven tests at domestic/foreign certified institutions and ensuring quality according to defense/foreign standards
