摘要： 由于燃料价格的迅猛增涨和严格的环境限制，设计轻质量车辆是目前汽车商家的一个主要议题。该文以镁合金座椅框架来替代传统的钢座椅框架。除了较高的材料费用以外，镁合金座椅框架具有较轻的质量和优良的吸收震动的能力。但是，镁合金的强度低于钢。对于框架的多数受力部件的设计因素进行了计算，并用正交矢量表方法进行了敏感性分析。利用LS-Dyna软件，模拟了该正交矢量方法。用Taguchi方法分析了模拟结果，以便找到影响受力和质量的设计因子。新设计的镁合金座椅框架提升了应力强度和刚性强度。

Abstract:  Recently, due to the rapidly increasing fuel price and strict environmental alregulation, light mass vehicle design is one of the major issues in the auto makers. In this study, magnesium alloy seat frame was used to substitute conventional steel seat frame. Despite of higher material cost, the magnesium seat frame can be less mass as well as an excellent vibration absorption capacity. However, the strength of magnesium is lower than that of steel. Design factor on the most stressed parts of the frame were calculated and sensitivity analysis was conducted using orthogonal array table. The orthogonal array models were simulated with LS-Dyna software. The simulated results were analyzed by Taguchi method to find the most influencing design factors on stress and mass. The strength of new designed magnesium alloy seat frame is improved in both strength and stiffness.
