Abstract X-in-the-loop (XiL) enables testing of a hardware prototype considering the remaining system by emulation of the system behavior to support early validation in the context of frontloading. To test a scaled prototype integrated in a remaining system, an adjustment of the rotational quantities between the prototype and remaining system is necessary. It is currently unclear, how scaling factors based on similarity methods adapt rotational quantities in a real-time XiL test bench for simultaneous testing. In this paper, scaling factors for the adaptation of rotational quantities between interconnected systems are derived and verified to enable scaled component testing considering the remaining system. This enables simultaneous testing of powertrain components with different scaling in real-time. With the example of a safety clutch, the rotational quantities are adapted. Using the derived scaling factors, the clutch torque could be recreated by using a scaled clutch. This opens up new possible applications for simultaneous testing of systems with different scaling.

在 X-in-the-Loop 测试台上同时测试具有不同比例的动力总成子系统的旋转量比例

摘要 X-in-the-loop (XiL) 允许通过模拟系统行为来测试考虑剩余系统的硬件原型，以支持前端加载环境中的早期验证。为了测试集成在剩余系统中的缩放原型，需要调整原型和剩余系统之间的旋转量。目前尚不清楚基于相似性方法的缩放因子如何适应实时 XiL 测试台中的旋转量以进行同步测试。在本文中，导出并验证了用于调整互连系统之间旋转量的比例因子，以便在考虑剩余系统的情况下进行缩放组件测试。这使得能够实时同时测试具有不同比例的动力总成组件。以安全离合器为例，调整旋转量。使用导出的比例因子，可以通过使用比例离合器重新产生离合器扭矩。这为同时测试具有不同比例的系统开辟了新的可能应用。
