This sensor has a mother body, a center position, and a range. The figure is a sphere and the radius is same as range.
Figure 1 Tension Sensor
As shown in Figure 1, if a sheet body passes within the range of the sensor, the sensor output can be computed from the following equation.
where,
is a stress value and the result of
sensor.
is the local stress tensor of the
closest position of Element in the range of the sensor.
is the global stress tensor of the
closet position of Element in the range of the sensor. In the case of shell
element, is a
mid-stress acting on the neutral surface.
is the reference frame of the output
of the sensor. The x axis of is an expecting direction vector for
acting a tension force.
is the reference frame of the sensor.
The z axis of is the
normal direction vector of the tension sensor.
is the reference frame of the closest
position of Element in the range of the sensor. The y axis of the
