Research on Air-Supported Force Measurement Method and Air-Supported Triaxial Force Measurement Platform

In order to completely avoid the inter-axis coupling phenomenon in the triaxial force measurement process and improve the measurement accuracy, an air-supported force measurement method considering both supporting and force measurement is proposed. Based on this, a triaxial force measurement device without inter-axis coupling is constructed. The model of air-supported one-axis force measuring unit and air-supported triaxial force measurement device are established. An air-supported triaxial force measurement platform is developed to explore the measurement accuracy of the force in each axial direction and the Inter-axis coupling phenomenon. The experimental results show that the air-supported triaxial force measurement platform has the characteristics of “no Inter-axis coupling” and “high precision”. The measurement error of the air-supported triaxial force measurement platform is 0.17% in the x-axis direction and 0.10% in the y-axis direction.
