A jounce bumper is part of a vehicle’s shock-absorber system designed to absorb impact and dampen noise, vibration and harshness (NVH).
Features and benefits:
And keeping usual features of automotive jounce bumper:
Unique Blow-molding design:
DuPont has patented a Jounce Bumper design made in Hytrel® allowing a significant cost reduction to replace incumbent foam polyurethane (PUR).
Using non-linear Finite Element Analysis (FEA) and Expert System software developed by DuPont, the Jounce Bumper design can be tailored to specific OEM/vehicle static and dynamic requirements of the OEM.
Hytrel® provides stiffness, elasticity and durability required for this application.
DuPont Inclusive Application Development
DuPont can support and collaborate with OEMs, Tier 1 suppliers and molders at all stages of the development phases.
This support includes:
DuPont can evaluate and optimize the Jounce Bumper design based on vehicle road tests according to multiple criteria and driving conditions.
