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。
Due to the rapid increase in fuel prices and strict environmental restrictions, the design of lightweight vehicles is currently a major issue for car dealers. This paper replaces the traditional steel seat frame with magnesium alloy seat frame. In addition to the higher material costs, the magnesium alloy seat frame has the advantage of lighter weight and excellent vibration absorption capability. However, magnesium alloys have a lower strength than steel. The design factors of most of the force components of the frame are calculated, and the sensitivity analysis is carried out by orthogonal vector table method. The LS-Dyna software was used to simulate the orthogonal vector method. The Taguchi method was used to analyze the simulation results to find the design factors that affect the force and quality. The newly designed magnesium alloy seat frame enhances stress strength and stiffness.
