在弹簧试验机中，横向力和弯曲/扭转力矩以及垂直力的测量对于弹簧特性鉴定至关重要。为此，更先进的工业机器通常配备有多分量力传感器（MFT），该多分量力传感器由不同的传感器组成，每个传感器专用于单个力分量。然而，这种组装的MTF存在未解决的技术问题，即，不执行力矩测量并且难以管理周期性校准。为了克服这些问题，我们设计了一种六足形MFT，并将其集成到一种新型工业弹簧试验机中，从而实现简单的周期性校准，确保测量可追溯性，并测量力矩分量。目前的工作涉及系统的性能评估和验证。
In spring testing machines, measurement of transversal forces and bending/torsion moments, as well as vertical force, is crucial for spring characterization. For this purpose, the more advanced industrial machines are typically equipped with multicomponent force transducers (MFTs), composed by different sensors each one is dedicated to a single force component. However, such assembled MTFs present unsolved technical problems, i.e. moment measurements are not performed and the periodic calibration is hard to manage. To overcome these problems, a hexapod-shaped MFT was devised and integrated into a new model of an industrial spring testing machine, thus enabling simple periodic calibrations and ensuring measurement traceability, as well as measuring the moment components. The present work deals with the performance evaluation and metrological validation of the system.
