- Safer child restraint systems are necessary to protect young passengers and to reduce liability to manufacturers. The amount of load that a child will receive to his or her head and chest during a collision can be accurately predicted, thereby allowing engineers to quickly optimize new designs. Using CAE, Prime Polymer has been able to optimize child restraint systems, allowing them to pass required impact tests. In many cases, our CAE analyses have enabled engineers to optimize their designs to such a great extent that the restraint systems have passed actual vehicle crash tests on the very first try.
- The initial design of the child restraint system (at the top of image plane) shows large deformations, allowing the child's head to hit the vehicle's front seat or an interior panel The improved design shows much less deformation and prevents the head from striking interior sections of the vehicle.
- The improved design includes new rib positions as well as reduced part thicknesses resulting in a 5% reduction in part weight.
- Material is Polypropylene; Speed of collision is 50 km/hr.
