Method for determining maximum plastic deformation of specific part of passenger compartment of vehicle i.e. car, involves comparing target value of criticality to specific value, and changing initial vehicle data

摘要

The method involves determining an indicator of criticality of impact on an occupant (50) of a vehicle from initial geometric data of design of the vehicle and from initial data of other known vehicles. The indicator of criticality is compared with target value of criticality. Maximum plastic deformation of the specific part is determined by a criticality flag by comparing the target value of criticality to a specific value and by changing initial vehicle data that is taken into account during designing process. An independent claim is also included for a car.
