Description

Technical Field

[0001] The present application relates to the technical field of catheter testing, and in particular to an aviation variable-form catheter testing device and method. Background Art

[0002] A variable-form conduit is a conduit whose tube structure can be stretched, compressed, bent, and deformed under external forces. It is mainly used in the piping system of aircraft motion mechanisms. Typical aviation variable-form conduits include plastic hoses, bellows, etc. Compared with the commonly used hard pipe connection, the variable-form conduit can change the spatial position of the interfaces at both ends of the conduit while transporting the medium, and plays an irreplaceable role in the joints of the motion mechanism. At the same time, due to the characteristics of its own structural deformation, compared with the service environment of the hard pipe, the variable-form conduit needs to additionally consider the working load of the mechanism deformation process and the environmental vibration stress level under different appearance states.

[0046] like Figure 1 As shown, an aviation variable form catheter test device provided by an embodiment of the present application includes two motion mechanisms, two vibration sources 6, a monitoring system 8 and a processing module. According to the installation state and structural variation range of the catheter 9 to be tested in the actual product, the two vibration sources 6 are adjusted to appropriate positions respectively, the motion mechanism is detachably connected to the vibration source 6 by bolts, the motion mechanism changes according to the spatial position and spatial angle in the actual working environment of the catheter 9 to be tested, the two motion mechanisms are adjusted to appropriate positions, the monitoring system 8 is adjusted to a position convenient for collecting image data of the catheter 9 to be tested, and the processing module is electrically connected to the two motion mechanisms, the two vibration sources 6 and the monitoring system 8 respectively.

[0047] A complex variable form duct test method was designed, in which the duct structure can be dynamically adjusted while applying a vibration environment, to achieve accurate testing and reliability evaluation of the dynamic service performance of complex variable form ducts;

[0048] A vibration environment loading mode with dual vibration source input is designed and used in conjunction with the monitoring system 8 to correct the input data, which greatly improves the consistency between the catheter environment and the actual service environment. It is more accurate than the traditional single vibration source input method, and is particularly effective in the testing of long catheters and hose structures. The equivalent load deviation is reduced by more than 50% compared with the traditional single vibration source method.

[0049] Specifically, the first rotating shaft 2 and the second rotating shaft 3 in the motion mechanism realize the adjustment of the spatial angle of the catheter end; the horizontal moving platform 5 realizes the adjustment of the spatial horizontal position of the catheter end; the horizontal rotating shaft 4 is mainly used, and the telescopic rod 1, the first rotating shaft 2 and the second rotating shaft 3 are auxiliary, to realize the displacement compensation of the spatial horizontal position of the catheter end; the telescopic rod 1 realizes the position adjustment of the catheter in the vertical direction, and the first rotating shaft 2 and the second rotating shaft 3 realize the displacement compensation of the catheter in the vertical direction.

[0050] The motion mechanism is used to simulate the complex movements of the tested conduit 9, while ensuring the accuracy of the spatial position and spatial angle of the tested conduit joint 7; the real-time dynamic monitoring system 8 can record the failure type, position, start time and failure process. The input and output interfaces are universal, suitable for common models of vibration source 6 devices and common aviation conduits, with high compatibility and interchangeability, and highly applicable in aviation pipeline testing.

[0051] The motion mechanism includes a catheter joint 7, a telescopic rod 1, a first rotating shaft 2, a second rotating shaft 3, a horizontal rotating shaft 4, and a horizontal moving platform 5, so that the processing module can control the motion mechanism to change the spatial position and relative angle of the catheter 9 to be tested in real time.

[0052] The actual working environment vibration spectrum of the catheter is realized by posting isotropic strain gauges on the catheter structure as piezoelectric sensors, connecting the strain gauge data collector, and placing it in actual working conditions to collect a complete periodic vibration spectrum.

[0053] The monitoring system 8 is a 360° panoramic high-definition motion camera. The collected data is uploaded to the mobile workstation in real time. The image data is periodically analyzed through image recognition software. When the opening distance of a crack at a certain part of the catheter exceeds the preset value and the number of image analysis samples exceeds the risk value, the system automatically sends a prompt message to the on-duty personnel to serve as a failure warning.

[0054] Optionally, the processing module of this embodiment can use an AT89S51 chip. AT89S51 is a low-power, high-performance CMOS 8-bit processor. The chip integrates a general-purpose 8-bit central processing unit and an ISP Flash storage unit, which can process the received information in a timely and effective manner. It should be noted that the processing module can be an integrated circuit chip with signal processing capabilities. The processing module can be a general-purpose processor, including a central processing unit, a network processor, etc.; it can also be a digital signal processor, an application-specific integrated circuit, a field programmable gate array or other programmable logic device, a discrete gate or transistor logic device, a discrete hardware component. It is not limited to the AT89S51 chip in this embodiment.

[0055] It can be seen that the device of this embodiment can solve the problem of reliability evaluation of dynamic service tests on deformable catheters with complex structures, accurately evaluate the dynamic service performance of aviation variable-form catheters under actual conditions, block product quality risks at the source, and improve product service reliability and safety.

[0056] Reference Figure 2 Based on the aviation variable form duct testing device of the aforementioned embodiment, an aviation variable form duct testing method provided by the embodiment of the present application includes:

[0057] S1, connecting the two ends of the catheter 9 to be tested to the two motion mechanisms respectively;

[0058] In the specific implementation process, the length of the conduit 9 to be tested is roughly determined by visual inspection or simple tools, and the distance between the two vibration sources 6 is adjusted based on the length of the conduit 9 to be tested, so that the two ends of the conduit 9 to be tested can be respectively installed on the two motion mechanisms.

[0059] Optionally, before performing this step, it is necessary to select a suitable motion mechanism for connecting the joint of the catheter 9 to be tested according to the size of the catheter 9 to be tested, so as to more stably install the catheter 9 to be tested on the motion mechanism.

[0060] S2, the processing module controls the two motion mechanisms to operate according to the structural deformation parameters to change the spatial positions and spatial angles of the two ends of the catheter 9 to be tested;

[0061] In the specific implementation process, the displacement signals of the connection positions at both ends of the catheter 9 to be tested in the actual working environment are collected, and the displacement signals are transmitted to the processing module. After being processed by the processing module, a control signal is sent to the motion mechanism. By precisely controlling the changes in the spatial position and spatial angle of the joints of the motion mechanism, the structural changes of the catheter 9 to be tested under the actual operating conditions of each mechanism are completely simulated.

[0062] Optionally, in this embodiment, sensing equipment may be installed at the connection positions of the two ends of the catheter 9 to be tested in the actual working environment, or motion image acquisition and analysis may be performed through a camera to collect displacement signals at the connection positions of the two ends of the catheter 9 to be tested.

[0063] S3, the processing module controls the two vibration sources 6 to operate according to the operating parameters of the vibration source 6 to simulate the actual vibration environment of the conduit 9 to be tested;

[0064] In the specific implementation process, the method for obtaining the operating parameters of the vibration source 6 of the measured catheter 9 in the actual working environment is: posting axial strain gauges on each structure of the measured catheter 9 as piezoelectric sensors, connecting the strain gauge data collector, and placing it in the actual working condition to collect the operating parameters of the vibration source 6.

[0065] The collected operating parameters of the vibration source 6 are input into the processing module, and the processing module controls the two vibration sources 6 to vibrate, thereby simulating the vibration frequency at both ends of the conduit 9 to be tested.

[0066] Optionally, a strain gauge may be installed on the conduit to be tested 9 by calculation or during simulation to detect the kinetic energy loss when the vibration passes through the motion mechanism, thereby being able to more closely simulate the actual working environment.

[0067] S4, collecting data of the catheter to be tested 9 based on the monitoring system 8 to obtain detection data of the catheter to be tested 9;

[0068] In the specific implementation process, the detection system is used to monitor the catheter 9 to be tested and the motion mechanism in real time and dynamically to verify the consistency between the catheter position test environment and the actual service status. At the same time, the real-time service status of the catheter 9 to be tested is monitored and the entire service process of the catheter 9 to be tested is recorded in time. If failure occurs, the failure type, location, start time and failure process can be recorded.

[0069] Optionally, the monitoring system 8 includes a 360° panoramic high-definition motion camera, and the collected image data of the catheter to be tested 9 is uploaded to the processing module in real time.

[0070] S5. The processing module evaluates the performance of the catheter 9 to be tested based on the detection data.

[0071] In the specific implementation process, the image data collected by the monitoring system 8 is transmitted to the processing module, and the image recognition software in the processing module periodically analyzes the image data. When the opening distance of a crack at a certain point in the catheter exceeds the preset value, the system automatically sends a prompt message to the on-duty personnel, which serves as a failure warning.

[0072] It can be seen that the method of this embodiment can solve the problem of reliability evaluation of dynamic service tests on deformable catheters with complex structures, accurately evaluate the dynamic service performance of aviation variable-form catheters under actual conditions, block product quality risks from the source, and improve product service reliability and safety.

[0073] The technical solution of the present invention can be extended to other pipeline components. The precise control of the motion mechanism can be used as the input for testing the assembly stress of the pipeline components. In addition, the pipeline system connected at the joint can also simulate the service behavior under the environment of duct air pressure, oil pressure, etc., which has rich application potential and expansion paths.

[0074] like Figure 3 As shown, Figure 3An experimental example provided in this application involves a sewage duct equipped with a certain type of aircraft cabin door opening position. The structure of the sewage duct equipped with a certain type of aircraft cabin door opening position is a variable form duct of "straight pipe-hose-straight pipe". The vibration level at this position is high, the opening frequency is high, and the duct cracking failure often occurs, polluting the cabin environment. The specific steps of using the method of the above embodiment to perform a dynamic service test on the sewage duct equipped with a certain type of aircraft cabin door 11 opening position are as follows:

[0075] S11. Establish a rectangular coordinate system with the rotation axis of the hatch 11 as the origin, obtain the spatial position of the measured guide and the interface A at the pipe wall plate end and the interface B at the guide door end during the opening and closing of the hatch 11, and the change state of the spatial angle with the movement time, adjust the motion mechanism to adjust the relative positions of the joints at both ends of the measured guide 9, and ensure that the actual working condition movement space range and path changes are fully covered.

[0076] S12. The straight section of the conduit 9 to be tested is a 20mm flared conduit. HB standard parts, outer nut, flat nozzle, straight joint, and combined tooling for welding outer nut and gasket and matching clamps are selected. The two ends of the conduit 9 to be tested are respectively connected to the joints of the motion mechanism on both sides.

[0077] After full connection, the motion mechanism is adjusted so that the spatial position and spatial angle of the two ends of the catheter 9 to be tested are in the state where the hatch 11 is closed; according to the structural state of the spatial position and spatial angle of the two ends of the catheter 9 to be tested changing with time during the process of opening and closing the hatch 11, the test mechanism simulates the structural state of the process in real time. The mechanism runs 3 to 5 times, and there is no interference or jamming in the structure, and the running state is normal.

[0078] S13. Under actual working conditions, the operating parameters of the vibration source 6 at the positions of the hatch 11, the wall panel 10, and the two ends of the duct to be tested 9 are collected, the operating parameters of the vibration source 6 are used as input conditions to start the vibration source 6, and the vibration source 6 is debugged until the measured vibration spectrum data at the two ends of the duct to be tested are consistent with the collected data.

[0079] S14. According to the normal frequency and speed of opening and closing the hatch 11 during the operation of the product, the structural operation state simulation of the hatch 11 opening and closing process is completed in the vibration environment of operation, driving the duct 9 to be tested to deform periodically.

[0080] S15. During the test, the dynamic monitoring system 8 displayed that the mechanism was operating normally, and the data collection indicators were normal. At 152 hours into the test, the monitoring system 8 showed that a crack appeared at the connection between the straight section and the hose section of the tested conduit 9; at 161 hours into the test, the monitoring system 8 showed that the crack at that location had expanded half a circle in the circumferential direction; at 163 hours into the test, the monitoring system 8 showed that the location was completely broken, and the two sections of the conduit were separated.

[0081] It can be seen that the experimental example provided in the present application obtains the fracture conditions of the aviation variable form catheter at different positions as the experimental time increases by real-time monitoring and recording of the catheter 9 to be tested, so as to further evaluate the dynamic service performance of the aviation variable form catheter, block product quality risks from the source, and improve product service reliability and safety.

[0082] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
