[0068] Before describing this embodiment, first explain the basis of this embodiment:
[0069] First, the representation form of the space vector symbol of the present invention is described, for example The whole of each parameter is specified as a form:
[0070] The main body of the symbol represents a space vector, Q represents a generalized force including force and moment, F represents a force, and M represents a moment; Δ represents a generalized deformation displacement of deformation including linear displacement and rotational angular displacement, ΔD represents linear deformation displacement, and Δθ represents rotational angular deformation Displacement; r represents the distance between the origin of the local coordinate system in the global coordinate system and the origin of the global coordinate system, and β represents the rotation angle of the local coordinate system around the three axes of the global coordinate system;
[0071] The superscript in the upper...

[0131] Through the process of the first embodiment, it can be seen that as long as the micro-displacement of the load platform of the multi-dimensional force sensor is obtained, the multi-dimensional force can be obtained.
[0132] This embodiment is a method for measuring the micro-displacement of a load platform of a multi-dimensional force sensor, including the following steps:
[0133] In the solution process of specific implementation mode 1, a very important step is to specifically solve the deformation displacement of the load platform in the global coordinate system And solving this deformation displacement depends on the micro-displacement sensor installed on the six-dimensional force sensor, and / or, the strain gauge installed on the strain beam, and / or, adopts piezoelectric crystal as the strain beam; Micro-displacement sensor, strain gauge or Piezoelectric crystal strain beams are collectively referred to as measurement sensitive elements;
[0134] solve The fir...

[0186] This implementation mode is the installation method of the measurement sensitive element of the multi-dimensional force sensor, which refers to the installation method in which the observable quantity along / around the sensitive axis in the local coordinate system can be obtained through the decoupling installation method of the measurement sensitive element, and the obtained observable quantity is, namely The variables on the right side of the coordination relationship equations;
[0187] The installation method of the measurement sensitive element is that the measurement axis of the measurement sensitive element coincides with the coordinate axis of the local coordinate system, and the measured quantity is the observable quantity; the described measurement sensitive element is only sensitive to one or several axes along / around , but not sensitive to along / around other axes, and when there are several sensitive axes, there is a decoupling relationship between different s...
