Abstract

Safety is the main design factor for any designer who creates or develops a new object. Involving aluminium to design the car longitudinal members has many benefits such as decreasing weight, decreasing the environment pollution and reducing fuel consumption. Bi-Metallic longitudinal member is created with both steel and aluminium materials. Four types of trigger have been modified, circular, elliptical, triangular and beaded to reduce the peak load and enhance the energy absorption values. Moreover, the percentage and position for the trigger geometry is studied. Circular trigger with 5% reduction was chosen as the best trigger due to enhancing energy absorption and reducing the peak load values.

研究不同触发机制下双金属矩形薄壁管
安全是任何设计人员创造或开发新物体的主要设计因素。采用铝材设计汽车纵向构件具有减轻车身重量、减少环境污染和降低油耗等诸多优点。双金属纵向构件由钢和铝材料制成。对圆形、椭圆、三角形和串珠四种类型的触发器进行了改进,以降低峰值负荷,提高能量吸收值。此外,还研究了触发几何的百分比和位置。由于能增强能量吸收和降低峰值负载值,选择减小5%的圆形触发器作为最佳触发器。通讯:Haidar Fadhil Al-Qrimli,科廷大学机械工程系,CDT 250 98009,马来西亚米里,电话:+60 85 443939;传真:+ 6085443837;电子邮件:haidar.fa@curtin.edu.my
