项目研发中基于轻量化的仪表板横梁参数优化分析

Parameter Optimization Analysis of Dashboard Beam Based on Lightweight in the Project Research and Development

近年来,国内汽车工业迎来了快速发展期,国内汽车保有量稳步增长。然而,由此带来的能源消耗及环境保护等问题则日益紧张,这必将阻碍国内汽车工业的可持续发展。汽车轻量化技术作为汽车降低能耗、减少排放的有效措施,已经成为汽车工业发展过程中的一项关键性研究课题,而轻量化也成为国内外各汽车厂商的核心竞争技术之一。前期设计研发中参数化分析的介入,给仪表板横梁轻量化提供了可能。论文中使用ANSA前处理软件,分析仪表板横梁在整个系统中的一阶固有频率,找到支架上的薄弱环节后进行结构改进和分析。如此反复叠加优化分析,最终在满足性能要求的前提下实现了减重优化。

In recent years, the domestic automobile industry ushered in the rapid development, it has been a steady rise in domestic car ownership. But the resulting problems of energy consumption and environmental protection is increasingly strained, this will hinder the sustainable development of domestic automobile industry. As an effective measure to reduce energy consumption and emissions,automobile lightweight technology has become a key research topic in the development process of automobile industry, the lightweight car manufactures at home and abroad have become the one of the core competitive technology. The intervention of parametric analysis in early design, research and development provides the possibility for the light quantization of the cross car beam. In this paper, ANSA preprocessing software is used to analyze the first order natural frequency of the panel beam in the whole system, and structural improvement and analysis are carried out after finding the weak links on the bracket. Finally, the weight reduction optimization is realized on the premise of satisfying the performance requirements.
