Calibration principle of six dimensional imported force sensor

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

F=CV

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.

Product overview:

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.

 Xuzhou imported force sensor

Application fields of six axis force sensor:

This product is widely used in remote control robot, robot surgery, robot arm research, finger force research, precision assembly, automatic grinding, contour tracking, hands coordination, zero force teaching and other operations. It is widely used in aviation, aerospace, mechanical processing, automobile and other industries.

Six dimensional imported force sensor features:

1、 The elastic body of the sensor adopts patent structure, with high sensitivity, good rigidity, small coupling between dimensions and mechanical overload protection function.

2、 The integrated decoupling bridge signal is synthesized into six components in three-dimensional space, which can be directly used for force control.

3、 Standard serial port and parallel port input and output are adopted.

4、 The product can not only form a two-level computer system with the control computer, but also connect the terminal to form an independent test device.
