    Abstract: The present disclosure is directed to a platform balance 10 that is suitable for transmitting forces and moments in a plurality of directions. The platform balance 10 is adapted to support a test specimen, such as a large vehicle, in a test environment such as a wind tunnel. The platform balance 10 includes a frame support 12, 14 and at least three spaced-apart transducers 40, 40A coupled to the frame support 12, 14. Each of the transducers 40, 40A is sensitive about two orthogonal sensed axes. The transducers 40, 40A cooperate to provide signals indicative of forces and moments with respect to at least two orthogonal axes. Each transducer 40, 40A includes a transducer body having a support 46, 48 coupled to a sensor body 42 along an axis of compliance. The sensor body 42 is adapted to deflect about the two orthogonal sensed axes where the sensed axes are mutually orthogonal to the axis f compliance.

    Abstract: A method of determining onset of a significant event, such as point of engagement, in experimental data (302, 402) such as data measured during indenter (100) or tensile/compression tests. The measured data (302, 402) is processed by differentiation (412, 518) and/or integration (414, 522) to generate a plurality of processed series (413, 415, 417, 512, 524, 532). The method includes setting an upper bound (806, 906) and a lower bound (808, 908) based on thresholds selected as multiples (424, 530) of a standard deviation (421, 528). The significant event (602, 810) is determined from one or both of the upper and lower bounds (806, 906, 808, 908). The method can include calculating an uncertainty (308, 408, 542) for the significant event determination (602, 810).

    Abstract: A process (50) for removing a modulation sinusoidal error from signals of a rotating load cell measuring forces and/or moments with respect to a non-rotating orthogonal coordinate system includes mounting the load cell to the rotating object and obtaining a first set of signals from the load cell, wherein at least one signal of the first set of signals is indicative of a load as the object rotates. A characterization of a modulation error is obtained from the first set of signals. The modulation error is a periodic signal having a frequency greater than and proportional to a frequency of revolution of the load cell. A second set of signals is calculated as a function of the characterization of the modulation error from the first set. The calculated modulation error in the second set of signals is substracted from the second set of signals.
