X-in-the Loop (XiL) enables component tests concerning the remaining system to support early validation in the context of frontloading. The system under test is connected with the physical or virtual remaining system. The performance variables of the bidirectional interactions must be adapted to the prototype, especially for testing a scaled prototype integrated into a remaining system. By applying a scaling, the bidirectional interactions between the test object and the remaining system can be considered in a scaled way. It is currently unclear how mass-based effects can be considered in the scaling model to reflect the behavior of unscaled systems.

In this paper, the influence of mass-based effects on the adaptation of rotational quantities between interconnected systems is analyzed and compensated by virtual inertias to allow scaled component tests considering the remaining system. Using the example of a torque limiting clutch from a geared rotary actuator out of an aircraft, the influences of the rotational inertia of the drive shaft on the scaling are analyzed in a simulation study.

The simulation shows an influence of the rotational inertia on the scaling and the system behavior if these effects are not considered in the scaling. The determining influence is taken into account in the scaling laws using adapted scaling laws by the integration of virtual inertia within the scaling.

The results show that virtual inertia can be added to the scaling model to reflect mass-based effects in behavior. This enables simultaneous testing of powertrain components with different scaling in real-time.

X-in-the Loop (XiL) 支持有关剩余系统的组件测试，以支持前端加载环境中的早期验证。被测系统与物理或虚拟剩余系统相连。双向交互的性能变量必须适应原型，特别是用于测试集成到剩余系统中的缩放原型。通过应用缩放，可以以缩放的方式考虑测试对象和其余系统之间的双向交互。目前尚不清楚如何在缩放模型中考虑基于质量的效应以反映未缩放系统的行为。

在本文中，基于质量的效应对互连系统之间旋转量的适应性的影响进行了分析，并通过虚拟惯性进行了补偿，以允许考虑剩余系统的缩放组件测试。以飞机的齿轮旋转执行器的扭矩限制离合器为例，在仿真研究中分析了驱动轴的转动惯量对缩放比例的影响。

如果在缩放中不考虑这些影响，则模拟显示旋转惯量对缩放和系统行为的影响。通过在缩放中集成虚拟惯性，使用适应的缩放定律在缩放定律中考虑确定影响。

结果表明，虚拟惯性可以添加到缩放模型中，以反映行为中基于质量的影响。这使得能够实时同时测试具有不同比例的动力总成组件。
