亚堔工业大学汽车工程学院先进电动汽车架构体系经理Dipl.-Ing. Johannes Stein

个人简介：

工学硕士约翰内斯-斯坦于2012年在亚堔工业大学获得机械工程硕士学位，此后，在亚堔工业大学汽车工程研究院（ika）车身部门成为工程师和研究助理，2013年他加入亚堔工业大学汽车工程学院的车辆概念部门。自2017年7月以来担任汽车工程学院的先进电动车辆架构体系的经理。

演讲摘要：

演讲介绍了一整套的开发方法，提出了总体车辆开发的框架条件。关注重点是效率和安全，提出了全面综合的轻型设计方法，包括几何形状和概念方面的工具手段以及材料轻型化的设计等。根据这种轻型化方法，设计出一款 CFRP-Al-space-frame车身，并对总体车辆模拟仿真的情况，就欧洲新车评价规程中关于安全要求进行了分析。有限元法（FEM）是对车辆概念被动安全进行分析的工具。除了动态模拟仿真之外，为了达到600公斤的目标重量， epsilon概念还被置于连续不断的重量管理之中。静态模拟仿真显示出车辆具有非常良好的弯曲和扭转刚性以及非常良好的轻型质量指标。

Abstract of speech

Within the following presentation, a methodological package development is shown, which sets the framework conditions for the overall vehicle development. Focusing on efficiency and safety, a holistic lightweight design approach is presented, including the tools of geometric, conceptual and material lightweight design. Based on this lightweight approach, a CFRP-Al-space-frame body is designed and analysed in an overall vehicle simulation regarding the safety requirements of Euro NCAP. The Finite Element Method (FEM) is the tool to analyse the passive safety of the vehicle concept. In addition to the dynamic simulations, the epsilon concept is subjected to a continuous weight management to reach the weight target of 600 kg. Static simulations show a very good bending and torsional stiffness of the vehicle as well as a very good lightweight quality index.
