Front Structure Crash and Occupant Safety


Fundamentals of passive safety are important in order to help design a car that is able to meet the demanding legal and consumer requirements. For instance, vehicle crash pulse generally reveals the structural behavior as well as the vehicle motion in a crash event, particularly in a front crash. On the other hand, restraint design is often dependent on the crash pulse. Therefore, a good understanding of the passive safety concept will enable a smooth integration of the vehicle structure and restraint system. At present, there are many advanced restraint components available in the market and the challenge now is to integrate them together in order to create an effective restraint system. This seminar aims to introduce the fundamentals of passive safety concept. Overview of the basic laws related to the impact and restraint system design will also be discussed to explain the important concept of front restraint system. Next, we will provide comprehensive explanation on the interpretation of the occupant injury values in the context of front crash and also on the working principle of the restraint components. Important aspects of the restraint component integration, restraint system design and optimization strategies will also be discussed during the seminar in order for the audience to have an in-depth understanding of this topic.


This seminar is suitable for vehicle development engineers, who are new in the area of front crash and responsible for the front restraint system design, or project managers who are responsible for the topics related to front crash impact, and those who would like to gain a deeper understanding of the front restraint system development.
