1991年12月19日,航空航天部科学技术研究院主持了我院金向林等负责的“多维动态力传感技术研究”的技术鉴定。 该课题组对多维动态力传感器的静态和动态精度问题进行了全面的研究,创造性地提出了用以解决应变式多维动态力传感器刚度与灵敏度矛盾的“主从弹性元件设计方法”,并首次成功地应用了消除传感器各维间相互干扰的“附加应变片补偿方法”,同时建立了有关的物理、数学模型,进行了相应的理论分析。结果表明,上述方法在提高传感器的灵敏度、
December 19, 1991, Institute of Science and Technology of the Ministry of Aeronautics and Astronautics presided over the technical evaluation of “multidimensional dynamic force sensing technology research” such as Jin Xianglin of our institute. The research team conducted a comprehensive research on the static and dynamic accuracy of multidimensional dynamic force sensors and creatively proposed the “master-slave elastic component design method” to solve the contradiction between the stiffness and sensitivity of strain-type multidimensional dynamic force sensors. For the first time, In addition, the “additional strain gauge compensation method” that eliminates the mutual interference between the various dimensions of the sensor is applied. At the same time, the related physical and mathematical models are established and the corresponding theoretical analysis is carried out. The results show that the above method is to improve the sensitivity of the sensor,
