Basic ideas for front collision strap design

Zhang Lu Yang Zhigang Lin Xianghui

Abstract：Based on the structural design of frontal collision， this paper expounds the basic idea of frontal collision design. It includes： the design that is strengthened step by step from the outside to the inside to ensure the basic design points of the living space; the design points of the planning of the force transmission path of the whole vehicle and the planning of the section force; at the same time， the selection of materials and material thickness， and the welding quality are also described. The impact on crash safety and the method of design or selection.

Key words：Positive collision， Croppedness， Crossing step by step， Section planning
