摘 要：本文以正面碰撞的結(jié)構設計為出發(fā)點，闡述正面碰撞設計的基本思路。包含：由外向內(nèi)逐級加強的設計，以保證生存空間的設計基本要點;整車受力傳遞路徑的規(guī)劃與截面力規(guī)劃的設計要點;同時，還闡述了材質(zhì)及料厚的選取、焊接質(zhì)量對于碰撞安全的影響以及設計或選取的方法。

關鍵詞：正面碰撞 耐撞性 逐級潰縮 截面力規(guī)劃

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
