Semi-combined pressure ring sensor and design method thereof

The invention discloses a semi-combined pressure ring sensor and a design method thereof, and relates to a sensor and a design method thereof. The sensor comprises an upper pressing plate, a pressure bearing ring, a lower pressing plate and an outer sleeve; the outer sleeve is installed on the lower pressing plate, the pressure-bearing ring is located in the outer sleeve, and the two ends of the pressure-bearing ring are connected with the upper pressing plate and the lower pressing plate respectively. The pressure-bearing ring is provided with n dividing seams, the pressure-bearing ring is uniformly distributed into n pressure-bearing areas, the cross section shapes and areas of the pressure-bearing areas are the same, and each pressure-bearing area is provided with a working groove and a measuring point groove I; the measuring point groove I is located in the middle line of the bottom of the working groove and internally provided with a measuring point. The method comprises the following steps: respectively
