新能源汽车副仪表盘设计与建模 DESIGN AND MODELING OF NEW ENERGY VEHICLE AUXILIARY DASHBOARD 摘要 在国内经济快速发展的当下，制造业特别是汽车制造业也迎来了发展的春天。目前能源和环境问题日益严重，发展新能源汽车是解决能源环境问题的有效途径，因此，对其进行设计和研究非常有意义。 本文结合了我国已有车型的结构布置方案，以及国内外典型车型的副仪表板内部结构设计，以CATIA软件为基础，对轿车的副仪表板进行工程可行性分析、空间布置、结构设计以及3D数据设计，最终完成3D数模。轿车副仪表板的设计是否合理与轿车后期的使用性能，该产品的可靠性以及人机舒适性等重要因素密切相关。 关键词内饰设计；轿车副仪表板；结构设计；可行性分析 Abstract With the rapid developme
