A Review of Dynamic Force Decoupling and Calibration Techniques

Dynamic force, a key measurement parameter in fields such as aerospace, material science, automobile manufacturing, and weapon efficacy, refers to force that varies over time. Ideally, dynamic force measurements should be unaffected by other sensor outputs, focusing solely on the test channel's directional output. Nevertheless, limitations in processing and installation technologies often result in inadvertent coupling of signals from other directions, leading to dynamic coupling. Accurate dynamic force measurements hinge on identifying the interdimensional coupling relationships among forces. Additionally, sensor calibration prior to testing is essential for enhancing measurement accuracy. Currently, the prevalent practice of using static calibration for dynamic force measurement often results in significant errors. Hence, the study and application of dynamic force decoupling and calibration methods are of paramount importance. This paper synthesizes various literature, summarizing common methods of dynamic force decoupling and calibration, comparing their strengths and weaknesses, and providing future perspectives.
