[0019] The present disclosure will be described in further detail below in conjunction with the accompanying drawings of the description, please refer to Figure 1 to Figure 4 .
[0020] Such as Figure 1 to Figure 4 As shown, taking the radial force measurement of an aircraft oil supply pipe as an example, the method for measuring the radial force of a rigid pipe according to the present disclosure includes the following steps:
[0021] Step 1. On the E-E section at a certain distance b from the head of the oil supply pipe, paste strain gauges R1 and R4, R1' and R4', R2 and R3, R2' and R3', such as figure 1 shown.
[0022] In other words, assuming that a coordinate plane (x, y) is established on a section perpendicular to the axial direction of the oil supply pipe as a rigid pipe (the distance between the section and the head of the oil supply pipe is, for example, b), the origin of the coordinates coincides with the center of the section, Then, at the intersections of th...

The invention provides a method of measuring a radial force of a rigid pipe. The method comprises steps: a coordinate plane (x, y) is built on a cross section axially vertical to the rigid pipe, a coordinate origin is overlapped with a cross section circle center, intersection points between x axis or y axis and the rigid pipe are respectively provided with a pair of strain gauges which are symmetrical relative to the x axis or the y axis and in adjacent connection, the strain gauges arranged at the x axis and the strain gauges arranged at the y axis form two groups of Wheatstone bridges respectively; output voltage of the two groups of Wheatstone bridges is detected; and at least according to the detected output voltage, the radial force is acquired. According to the measurement method disclosed by the invention, the radial force applied to an oil supply pipe can be measured when the plane rigid oil supply pipe and an oil receiving base are in docking oil transportation. The strain gauges are adopted to serve as basic measurement parts, the problem that the conventional measurement method can not measure the radial force can be solved, the design is simple and effective, and generality is good.
Description
technical field [0001] The present disclosure relates to the field of pipeline stress testing, in particular to a method for measuring the radial force of a rigid pipe. Background technique [0002] In the application of rigid pipes, such as the application of using rigid pipes as oil supply pipes, in order to protect the oil supply pipes from damage due to excessive radial force in the oil supply mode and increase the safety of the oil supply mode, the supply The radial force signal at the oil pipe and the oil supply object is very important. At present, there is no application of technology in this field in China. [0003] Conventional force measurement methods mainly measure the axial tensile and compressive forces of the measured object, and there is no application for measuring radial force. Contents of the invention [0004] The present disclosure aims to provide a novel method for measuring the radial force of a rigid pipe. [0005] According to an aspect of the ...
