动态力解耦和动态标定相关技术研究综述

A Review of Dynamic Force Decoupling and Calibration Techniques

随时间变化的力称作为动态力,其在航空航天、材料科学、汽车制造、武器威力等研究领域均为重要的测量参数。理想情况下,动态力测试与其他传感器输出无关,涉及的仅仅是测试通道方向的输出。但是,由于加工工艺、安装工艺等限制,在测量某方向动态力时,难免耦合其他方向的输出信号造成动态耦合,只有准确的找到各维间力的相互耦合关系,才可以达到精确测量动态力的目的。同时,在测试前应先标定传感器,以提高测量的准确性。目前多采用静态标定进行动态力测量的“静标使用”方法,在测量中必然会产生较大的误差。因此,动态力的解耦及动态标定具有较大的意义。通过分析相关文献,总结了动态力解耦和动态力标定的常用方法,对比优缺点并提出展望。

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.
