转向测试台架

验证电机转向系统

dSPACE提供了众多可扩展系统，从小型紧凑旋转测试台架到大型高性能转向测试台架都有，因此其测试范围十分广泛，涵盖了从机电电动助力转向组件乃至完整的转向系统。

  • 虚拟车辆中真实转向系统的行为分析
  • dSPACE HIL仿真器和Vehicle Dynamics模型的实时仿真（带有机电试验台）
  • 高精度可复现测试

主要优点

dSPACE测试台架允许创建用于运行虚拟驾驶测试的测试环境，并能在早期阶段对具有不同控制算法和功能算法的实际转向系统进行评估和分析。

这意味着早在车辆集成之前，就可以对驾驶体验和驾驶安全的需求做出客观和主观的评价。其中的主要优势是测试的高度可复现性和适应性以及测试台架的广泛应用。

dSPACE转向测试台架的类型众多，从小型的紧凑旋转测试台架到大型的高性能转向测试台架（通过直线驱动器实现需要高动态和高精度的应用），应有尽有。

工业驱动逆变器的可用接口

dSPACE根据您的要求为工业驱动逆变器提供不同接口。

比如在转向应用中，为达到高性能，dSPACE采用了KEBA Industrial Automation Germany GmbH（原LTI Motion GmbH）的专用TWINsync接口。该接口是与KEBA一起开发的，PWM同步更新速率可达到0.125 ms。

针对HIL仿真以及电动助力转向系统等转向应用测试台架，dSPACE推出了全方位的产品组合。下表概述了使用HIL仿真器以及转向测试台架可能实现的一些应用场景。可以给每类测试台架添加特定项目的要求，例如使用人工气候室进行环境仿真。
