Abstract
In the process of side impact, the door was directly contacted with the chest, abdomen and pelvis of dummy and its movement has a large effect upon dummy injury. A evaluation about dummy injury influenced by the velocity and displacement of chest, abdomen and pelvis in dummy was proposed. A rapid forward development strategy which is applied in forward development was presented. A new type side impact LPM (Lumped-Parameter Model) was established. The stiffness of critical area in vehicle body was optimized by LPM which used the intrusive velocity and displacement of chest, abdomen and pelvis in dummy as design object. The example showed that the safety performance was improved obviously and the development period was shortened in some extent.
