本演示文稿描述了尼古拉电机从1D CAE到3D CAD / CAE的设计成熟的进展,用于电动卡车上的底盘系统工程工作。这一进展从客户的语音到功能要求到结构部署的功能要求。尼古拉电机以“第一原理”模型为主的卡车/拖车车辆动态,然后使用四分之一卡车/拖车型号使用Altair激活系统建模和仿真。使用基于信号的块和基于物理的块(使用ModelICA)来创建框图。Through this methodical process, Nikola Motor is able to derive more and better insight earlier in their development process regarding important vehicle characteristics for their trucks – ranging from ‘yaw rate of the tractor for loaded vs. unloaded trailer’ to ‘full-trailer load distribution sensitivity due to fifth wheel location’. Work is in-progress to tighten the connection between their 1D CAE simulations in Altair Activate™ and their 3D CAE multi-body dynamics simulations.
