👉 Crash fluid, also known as hydraulic absorbent material (HAM), is a specialized fluid used in automotive crash systems to manage and contain the energy generated during a vehicle collision. It is typically placed in the front bumper or other areas where impact forces are concentrated. When a crash occurs, the fluid absorbs and dissipates the kinetic energy, reducing the force transmitted to the vehicle's structure and occupants. This helps in minimizing damage to the car's frame, protecting passengers, and enhancing overall safety by controlling the deformation of the vehicle during a crash.
