摘　　要：为使乘用车在概念设计阶段正面抗撞性能得到控制和优化,以某中级轿车为例,提出了目标简化双台阶波形重要参数G1和G2的确定方法,并基于能量管理技术实现了总目标条件下的子结构性能目标的有效分解,为进一步的结构断面设计和总目标的实现提供了充分的设计依据。In order to control and optimize the frontal crashworthiness of the passenger car in the conceptual design phase, taking a B-class car as an example, a method of setting the important parameters G1 and G2 for the target simplified 2-step impact pulse in the conceptual design phase was proposed. The sub-structure performance targets were decomposed effectively under the overall goal condition based on the energy management technique, providing a sufficient basis for further ,structure sections design and overall goal achievement.
