Six dimensions Imported force sensor All of the calibration are based on the hypothesis sensor When the system is a linear system, the static mathematical model of the sensor meets the requirements
Where V is Six axis force sensor Output 6-channel original information (column information, unit is v), f is calculated 6-way force information (column information, force unit is kn, torque unit is knm) [6-7].
The essence of sensor static calibration is to use the force applied in six dimensions force sensor The calibration matrix C is obtained from the generalized force vector group F and the six output signal vector groups V of the sensor obtained by data acquisition and up sampling. The output signal of the sensor is a vector composed of six voltage signals. If the nonlinearity of the sensor is not considered, a unique solution C can be obtained by applying six linearly independent force vectors to the sensor and measuring the output voltage signal vector V corresponding to the six force vectors.
One of the world's smaller 6-DOF sensors with a compact and low profile design. The sensor has a middle through hole for connecting rod and cable. High strength, high strength stainless steel wire cutting processing, single axis overload is 5.7 to 25.3 times of the rated range. The signal of the silicon strain gauge is 75 times stronger than that of the traditional strain gauge with high signal-to-noise ratio. After the signal is amplified, the noise distortion is close to zero.
