Description

Technical Field

[0001] The invention relates to the technical field of rocket launching, and in particular to a design method of an umbilical cord swing arm pipeline guiding system and an umbilical cord swing arm pipeline guiding system. Background Art

[0002] Modern rockets require an air conditioning system for temperature control before launch. The air conditioning interface is located in the rocket body fairing area. At the moment of rocket ignition or within a set time before launch, the umbilical pendulum pipeline connector needs to be disconnected from the rocket body. Existing rockets generally use a redundant ball lock plug connector with a ball lock socket, a ball lock jacket, a locking jacket and a traction plate to connect the umbilical pendulum pipeline to the rocket body fairing.

[0003] Since the air conditioning interface is located at a high altitude from the ground, the high-altitude wind conditions and the large amount of shaking at the rocket air conditioning interface make the movement trajectory unstable during the unlocking process of the umbilical swing arm pipeline connector, and it fails to fall according to the preset trajectory, and even swings onto the rocket, causing damage to the rocket. Therefore, the umbilical swing arm pipeline needs to be fixed at a high position through the umbilical swing arm to achieve the connection between the air conditioning and the inside of the rocket body fairing.

[0004] Currently, the stability of the traction cable is generally analyzed by field test method. This test process is complicated, time-consuming, increases the construction and launch cycle of the rocket, and cannot meet the rapid launch requirements of commercial rockets.

[0059] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0060] like Figure 1 As shown, the design method of the umbilical swing arm pipeline guide system includes:

[0061] Step S1, design the basic structure of the umbilical swing arm pipeline guidance system according to the rocket launch requirements, and use a winch and a traction cable solution to guide the umbilical swing arm pipeline.

[0062] Specific components and infrastructure of the umbilical swing arm pipeline guidance system in accordance with the general requirements of the rocket launch site.

[0063] In this embodiment, the umbilical swing arm pipeline guiding system includes an umbilical swing arm, an umbilical swing arm pipeline, a connector, a winch and a traction rope, and the connector is a redundant ball lock plug-in connector.

[0064] Step S2: determine the size of the traction cable according to the rocket launch requirements and the position of the umbilical tower.

[0065] According to the model and size of the rocket and the conditions of the launch site, and according to the data such as the horizontal offset of the rocket during launch, the distance between the umbilical tower and the rocket can be determined. This process belongs to the conventional prior art and will not be described in detail here.

[0066] Step S3: Perform stability analysis on the traction rope by using finite element method and multi-body dynamics method to determine whether the connector can be unlocked under the dead weight of the traction rope and the umbilical swing arm pipeline.

[0067] Specifically, they include:

[0068] Step S31, calculating the gravity of the umbilical swing arm pipeline and the traction rope.

[0069] When calculating the gravity of the umbilical swing arm pipeline and the traction rope, the calculation can be performed based on the corresponding length and combined with the national standard weight. For example, the weight of a φ6 steel wire rope is 13.9kg / 100m according to GB / T8918, and the weight of a 4500mm steel wire rope is 0.63kg. Its gravity can be calculated based on the weight. In the same way, the gravity of the umbilical swing arm pipeline can be calculated.

[0070] Step S32: Calculate the equivalent axial tension of the umbilical swing arm pipeline and the traction cable at the connector end under the action of gravity.

[0071] According to the connection angle between the towing cable and the connector and the connection angle of the umbilical swing arm pipeline, and according to the gravity of the towing cable and the equivalent axial tension of the umbilical swing arm pipeline and the towing cable at the connector end can be determined in the finite element analysis model.

[0072] Step S33: determine the critical unlocking force of the connector on the umbilical swing arm pipeline.

[0073] Specifically, the brand, specification and model of the connector are determined according to the design requirements. The connector is a container product and can be selected according to the design requirements. Select multiple batches and multiple units of this type of connector for several unlocking tests, and record the connector's unlocking force in each unlocking test. Number each test in the order of the tests so that the test number corresponds to the unlocking force in the test. Determine the average or median of the unlocking force by statistical methods, and use the average or median as the critical unlocking force of the connector.

[0074] In this embodiment, more than 400 tests were conducted on a connector of a certain specification and model, and the average value of the release unlocking force of 571N was selected as the critical unlocking force of the connector. The test data of the critical unlocking force of the connector are as follows: Figure 2 shown.

[0075] Preferably, when selecting multiple batches and multiple units of this type of connector for unlocking test, the number of unlocking tests is not less than 50. According to the principle of statistics, the more the number of unlocking tests counted, the more reasonable the median or average is, so the number of unlocking tests is not limited in this way.

[0076] Step S34: determining the actual unlocking force according to the equivalent axial pulling force and the critical unlocking force of the connector.

[0077] Specifically, the actual unlocking force can be determined by performing a differential operation between the critical unlocking force and the equivalent axial tension of the umbilical swing arm pipeline and the traction cable at the connector end under the action of gravity. The unlocking force may be a positive number or a negative number.

[0078] Step S35, determine whether the actual unlocking force is within the preset range; if the actual unlocking force is within the preset range, the traction rope is designed according to this state; if the actual unlocking force is not within the preset range, the suspension size of the traction rope is adjusted until it meets the design requirements, thereby completing the design of the umbilical swing arm pipeline guide system.

[0079] In this embodiment, it is found through calculation that the actual unlocking force is 30N. Considering the redundant design, the finite element method and the multi-body dynamics method are used to analyze the tight force of the suspension cable. When the traction cable is in the non-suspended state, the equivalent axial tension at the left fixed end (connector end) is 362.3N, which is far from the actual unlocking force. The connector will be unlocked under the action of its own weight, so the cable suspension setting is performed, that is, the suspension size of the traction cable is adjusted.

[0080] By continuously increasing the overhang size of the traction rope, the connector is subjected to finite element analysis and dynamic analysis. When both analysis results are lower than the critical calculated load, the minimum overhang size that ensures the safety of the connector without unlocking is taken as the optimal overhang size.

[0081] Preferably, ANSYS software is used for finite element analysis, and Adamas software is used for dynamic analysis.

[0082] Preferably, when the traction cable is subjected to stability analysis by the finite element method and the multi-body dynamics method, the deformation of the traction cable needs to be calculated. By calculating the deformation of the traction cable, the winding size of the winch for the traction cable can be further confirmed to ensure the effective separation of the umbilical swing arm pipeline during rocket launch.

[0083] In this embodiment, a CABLE cable unit is used in the ANSYS software, with a length of 5m and a cross-sectional diameter of 6mm. First, the cable is fixed at both ends and analyzed under the deadweight load condition. The maximum deformation of the traction cable is 12.2mm. Therefore, when winding, the winding distance should be increased by at least 12.2mm.

[0084] Step S4: According to the stability analysis result of the traction rope, the hanging size of the traction rope is adjusted until the stability of the traction rope meets the design requirements, thereby completing the design of the umbilical swing arm pipeline guide system.

[0085] Preferably, after judging whether the actual unlocking force is within a preset range and adjusting the hanging size of the traction rope whose actual unlocking force is outside the preset range until the design requirements are met, the method further includes:

[0086] The strength of each component of the ball lock is analyzed by finite element analysis:

[0087] like Figure 3-6 As shown, the strength of the ball lock socket, the strength of the ball lock jacket, the strength of the locking jacket and the strength of the traction plate are analyzed by finite element analysis. Through the above analysis, it can be determined whether the ball lock meets the strength requirements under the pulling condition to avoid deformation or damage of the ball lock when it is pulled.

[0088] Compare the strength analysis results with the design requirements to determine whether the various components of the ball lock meet the requirements.

[0089] The ball lock components that do not meet the design requirements are optimized until the strength of the corresponding ball lock components meets the design requirements.

[0090] like Figure 7-9 As shown, the umbilical swing arm pipeline guide system is designed using the umbilical swing arm pipeline guide system design method, and includes: an umbilical swing arm 6, an umbilical swing arm pipeline 3, a connector 2, a winch 5 and a first traction rope 7.
