Description

Technical Field

[0001] The invention belongs to the field of engines and relates to a rotor dynamic balancing detection technology, in particular to an engine double-section rotor dynamic balancing method, equipment and medium based on data analysis. Background Art

[0002] Due to factors such as uneven materials, process errors, uneven deformation of rotor blades, uneven wear or partial block loss, there is always imbalance on the rotor, and rotor imbalance is the main source of excitation for the engine. Imbalance causes rotor vibration, accelerates the wear of bearings, shaft seals and other components, and reduces the service life and efficiency of the machine. For this reason, the rotor needs to be dynamically balanced during engine manufacturing or maintenance, and even during operation. Dynamic balancing is to change the mass distribution of the rotor by removing or adding weights to the rotor, so that the rotor vibration caused by the eccentric centrifugal force of the center of mass or the dynamic load acting on the bearing is reduced to within the allowable range, so as to achieve the purpose of stable operation of the engine.

[0003] In the prior art, the dynamic balancing method for the double-section rotor of the engine is to directly test it on the machine, and then determine whether the double-section rotor of the engine is dynamically unbalanced based on the test results. This method does not combine the dynamic balancing condition of the double-section rotor of the engine, nor does it set a suitable detection method based on the dynamic balancing condition. Therefore, the current dynamic balancing detection method has the problem of inaccurate detection;

[0004] To this end, the present invention proposes a method, device and medium for dynamic balancing a double-section rotor of an engine based on data analysis. Summary of the invention

[0005] The purpose of the present invention is to propose a method, device and medium for dynamic balancing of a double-section rotor of an engine based on data analysis to solve the problems raised in the above-mentioned background technology.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] The dynamic balancing method of the double-section engine rotor based on data analysis is as follows:

[0008] Step S10, the user module inputs the model of the dual-section engine rotor currently being balanced and corrected, and sends the model to the storage module, and the storage module sends the balance correction data corresponding to the dual-section engine rotor to the measurement and analysis module according to the model;

[0009] Step S20, the measuring and analyzing module analyzes the balance correction of the double-section rotor of the same type of engine, obtains the balance monitoring value of the double-section rotor of the same type of engine through analysis, and sends it to the intelligent setting module;

[0010] Step S30, the intelligent setting module sets the test parameters of the dynamic balancing test corresponding to the engine double-section rotor, obtains the test parameters of the dynamic balancing test corresponding to the engine double-section rotor and sends them to the data acquisition module;

[0011] Step S40, recording the engine double-section rotor that needs to be dynamically balanced as the double-section rotor of the engine to be tested, and the data acquisition module collects the real-time balance data of the double-section rotor of the engine to be tested during the dynamic balance test according to the test parameters and sends it to the balance analysis module;

[0012] Step S50, the balance analysis module analyzes the dynamic balance of the double-section rotor of the engine to be tested, generates a normal signal or an abnormal signal through the analysis and sends it to the display module, and the display module displays the abnormal signal or normal signal of the dynamic balance test of the double-section rotor of the engine to be tested.

[0013] Furthermore, the balancing correction data includes the usage time, the number of balancing corrections and the correction amount of each balancing correction of the double-section rotors of different engine models. The usage time is the time between the time the double-section rotor of the engine is put into use and the time the double-section rotor of the engine is first balanced and corrected.

[0014] Furthermore, the analysis process of the determination and analysis module in step S20 is specifically as follows:

[0015] According to the model, the balancing correction data of the double-section rotor of the same model engine in the storage module are obtained, and the use time STu, the number of balancing corrections JCu and the correction amount of each balancing correction of multiple groups of engine double-section rotors are obtained, where u is the number of the double-section rotor of the same model engine;

[0016] The correction amount of each set of double-section rotors of the same type of engine during each balancing correction is added and summed to obtain the total correction amount of each set of double-section rotors of the same type of engine during balancing correction. The total correction amount of each set of double-section rotors of the same type of engine is added and summed and divided by the number of double-section rotors of the same type of engine to obtain the average correction amount JLu of the double-section rotors of the same type of engine during balancing correction.

[0017] The balance monitoring value PJu of the double-section rotor of the same type of engine is calculated by the formula, and the formula is as follows:

[0018] PJu=(JLu×a1+JCu×a2) / STu; where a1 and a2 are proportional coefficients with fixed values, and the values ​​of a1 and a2 are both greater than zero.

[0019] Furthermore, the setting process of the intelligent setting module in step S30 is specifically as follows:

[0020] Obtain the balance monitoring value of the double-section rotor of the same type of engine obtained above;

[0021] comparing the balance monitoring value with a balance monitoring threshold, the balance monitoring threshold comprising a first balance monitoring threshold and a second balance monitoring threshold, the first balance monitoring threshold being less than the second balance monitoring threshold;

[0022] If the balance monitoring value is less than or equal to the first balance monitoring threshold, the test parameters of the dynamic balance test corresponding to the double-section rotor of the engine are: the first test number;

[0023] If the balance monitoring value is greater than the first balance monitoring threshold and less than or equal to the second balance monitoring threshold, the test parameters of the dynamic balance test corresponding to the double-section rotor of the engine are: the second test number;

[0024] If the balance monitoring value is greater than the second balance monitoring threshold, the test parameter of the dynamic balance test corresponding to the double-section rotor of the engine is: the third test number.

[0025] Furthermore, the first test number is smaller than the second test number, and the second test number is smaller than the third test number.

[0026] Furthermore, the real-time balancing data are the real-time position coordinates and real-time rotation trajectory of the test points during each test of the double-section rotor of the engine to be tested. There are two groups of test points, one group of test points is located at the center position of the double-section rotor of the engine to be tested, and the other group of test points is randomly located on the cross-section of the double-section rotor of the engine to be tested.

[0027] Furthermore, the analysis process of the balance analysis module in step S50 is specifically as follows:

[0028] Select an unused and qualified engine dual-section rotor of the same model, and record the engine dual-section rotor as a qualified engine dual-section rotor;

[0029] Setting test points on the qualified engine double-section rotor according to the real-time position coordinates, and performing a dynamic balancing test on the qualified engine double-section rotor, thereby obtaining a standard rotation trajectory line of the test points on the qualified engine double-section rotor;

[0030] Compare the real-time rotation trajectory of the test point with the same position coordinate with the standard rotation trajectory;

[0031] If the real-time rotation trajectory of any test point does not overlap with the standard rotation trajectory, the area of ​​the non-overlapping area is calculated and recorded as the non-overlapping area. When the non-overlapping area exceeds the preset area, an abnormal signal is generated. When the non-overlapping area does not exceed the preset area, the next dynamic balancing test is started.

[0032] If the real-time rotation trajectory of all test points overlaps with the standard rotation trajectory, the next dynamic balancing test will begin;

[0033] When the corresponding number of tests is reached, the real-time rotation trajectory lines of all test points overlap with the standard rotation trajectory lines, and a normal signal is generated.

[0034] In a second aspect, a computer device is provided, the computer device comprising:

[0035] A memory storing a computer program;

[0036] A processor is communicatively connected with the memory, and when the computer program is executed by the processor, a method for dynamic balancing of a double-section rotor of an engine is implemented.

[0037] In a third aspect, a computer-readable storage medium stores a computer program, which, when executed by a processor, implements a method for dynamic balancing a double-section rotor of an engine.

[0038] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0039] The present invention sends the balance correction data corresponding to the engine double-section rotor to the measurement and analysis module according to the model, analyzes the balance correction situation of the engine double-section rotor of the same model through the measurement and analysis module, and obtains the balance monitoring value of the engine double-section rotor of the same model through the analysis; the intelligent setting module sets the test parameters of the dynamic balance test corresponding to the engine double-section rotor according to the balance monitoring value, collects the real-time balance data during the dynamic balance test of the engine double-section rotor to be tested according to the test parameters, analyzes the dynamic balance situation of the engine double-section rotor to be tested through the balance analysis module, and generates a normal signal or an abnormal signal through the analysis; the present invention sets a corresponding detection method in combination with the dynamic balance situation, thereby realizing accurate detection of the dynamic balance of the engine double-section rotor.

[0045] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Embodiment 1:

[0047] See also Figure 1-Figure 3 As shown, the technical solution provided by the present invention is: a dynamic balancing method for a double-section rotor of an engine based on data analysis, and the method is specifically as follows:

[0048] Step S10, the user module inputs the model of the dual-section engine rotor currently being balanced and corrected, and sends the model to the storage module, and the storage module sends the balance correction data corresponding to the dual-section engine rotor to the measurement and analysis module according to the model;

[0049] Step S20, the measuring and analyzing module analyzes the balance correction of the double-section rotor of the same type of engine, obtains the balance monitoring value of the double-section rotor of the same type of engine through analysis, and sends it to the intelligent setting module;

[0050] Step S30, the intelligent setting module sets the test parameters of the dynamic balancing test corresponding to the engine double-section rotor, obtains the test parameters of the dynamic balancing test corresponding to the engine double-section rotor and sends them to the data acquisition module;

[0051] Step S40, recording the engine double-section rotor that needs to be dynamically balanced as the double-section rotor of the engine to be tested, and the data acquisition module collects the real-time balance data of the double-section rotor of the engine to be tested during the dynamic balance test according to the test parameters and sends it to the balance analysis module;

[0052] Step S50, the balance analysis module analyzes the dynamic balance of the double-section rotor of the engine to be tested, generates a normal signal or an abnormal signal through the analysis and sends it to the display module, and the display module displays the abnormal signal or the normal signal of the dynamic balance test of the double-section rotor of the engine to be tested;

[0053] In this embodiment, the above method involves a user module, a storage module, a measurement and analysis module, an intelligent setting module, a data acquisition module, a balance analysis module and a display module;

[0054] The user module is used to input the model of the dual-section engine rotor currently being balanced and corrected, and send the model to the storage module, the storage module is used to record the balance correction data of the dual-section engine rotors of different models, and the storage module is used to send the balance correction data corresponding to the dual-section engine rotor to the measurement and analysis module according to the model;

[0055] It should be specifically stated that the balancing correction data are the service life, the number of balancing corrections and the correction amount of each balancing correction of the dual-section rotors of different engine models. The service life is the time between the time when the dual-section rotors of the engine are put into use and the time when the dual-section rotors of the engine are first balanced and corrected.

[0056] The measurement and analysis module is used to analyze the balance correction of the double-section rotor of the same model of engine. The analysis process is as follows:

[0057] According to the model, the balancing correction data of the double-section rotor of the same model engine in the storage module are obtained, and the use time STu, the number of balancing corrections JCu and the correction amount of each balancing correction of multiple groups of engine double-section rotors are obtained, where u is the number of the double-section rotor of the same model engine;

[0058] The correction amount of each set of double-section rotors of the same type of engine during each balancing correction is added and summed to obtain the total correction amount of each set of double-section rotors of the same type of engine during balancing correction. The total correction amount of each set of double-section rotors of the same type of engine is added and summed and divided by the number of double-section rotors of the same type of engine to obtain the average correction amount JLu of the double-section rotors of the same type of engine during balancing correction.

[0059] The balance monitoring value PJu of the double-section rotor of the same type of engine is calculated by the formula, and the formula is as follows:

[0060] PJu=(JLu×a1+JCu×a2) / STu;wherein, a1 and a2 are both fixed proportional coefficients, and the values ​​of a1 and a2 are both greater than zero. The balance monitoring value is used to reflect the control strength of the dynamic balance of the engine double-section rotor, that is, the more the balance correction times, the greater the average correction amount, the shorter the use time, the greater the value of the balance monitoring value, and thus the more the engine double-section rotor needs dynamic balance correction;

[0061] The measurement and analysis module sends the balance monitoring value of the double-section rotor of the same type of engine to the intelligent setting module, and the intelligent setting module is used to set the test parameters of the dynamic balance test corresponding to the double-section rotor of the engine. The setting process is as follows:

[0062] Obtain the balance monitoring value of the double-section rotor of the same type of engine obtained above;

[0063] comparing the balance monitoring value with a balance monitoring threshold, the balance monitoring threshold comprising a first balance monitoring threshold and a second balance monitoring threshold, the first balance monitoring threshold being less than the second balance monitoring threshold;

[0064] If the balance monitoring value is less than or equal to the first balance monitoring threshold, the test parameters of the dynamic balance test corresponding to the double-section rotor of the engine are: the first test number;

[0065] If the balance monitoring value is greater than the first balance monitoring threshold and less than or equal to the second balance monitoring threshold, the test parameters of the dynamic balance test corresponding to the double-section rotor of the engine are: the second test number;

[0066] If the balance monitoring value is greater than the second balance monitoring threshold, the test parameters of the dynamic balance test corresponding to the double-section rotor of the engine are: the third test number;

[0067] The first test number is less than the second test number, and the second test number is less than the third test number. In practice, the first test number may be 2 times, the second test number may be 4 times, and the third test number may be 6 times.

[0068] The intelligent setting module sends the test parameters of the dynamic balancing test corresponding to the engine dual-section rotor to the data acquisition module, and records the engine dual-section rotor that needs to be tested as the engine dual-section rotor to be tested. The data acquisition module is used to collect real-time balancing data during the dynamic balancing test of the engine dual-section rotor to be tested according to the test parameters, and send the real-time balancing data to the balance analysis module;

[0069] It should be specifically stated that the real-time balancing data is the real-time position coordinates and real-time rotation trajectory of the test points during each test of the double-section rotor of the engine to be tested. There are two groups of test points, one group of test points is located at the center of the double-section rotor of the engine to be tested, and the other group of test points is randomly located on the cross section of the double-section rotor of the engine to be tested.

[0070] The balance analysis module is used to analyze the dynamic balance of the double-section rotor of the engine to be tested. The analysis process is as follows:

[0071] Select an unused and qualified engine dual-section rotor of the same model, and record the engine dual-section rotor as a qualified engine dual-section rotor;

[0072] Setting test points on the qualified engine double-section rotor according to the real-time position coordinates, and performing a dynamic balancing test on the qualified engine double-section rotor, thereby obtaining a standard rotation trajectory line of the test points on the qualified engine double-section rotor;

[0073] Compare the real-time rotation trajectory of the test point with the same position coordinate with the standard rotation trajectory;

[0074] like Figure 3 As shown, if the real-time rotation trajectory line of any test point does not overlap with the standard rotation trajectory line, the area of ​​the non-overlapping area is calculated and recorded as the non-overlapping area area. When the non-overlapping area area exceeds the preset area, an abnormal signal is generated. When the non-overlapping area area does not exceed the preset area, the next dynamic balancing test is entered;

[0075] If the real-time rotation trajectory of all test points overlaps with the standard rotation trajectory, the next dynamic balancing test will begin;

[0076] When the corresponding number of tests is reached, the real-time rotation trajectory lines of all test points overlap with the standard rotation trajectory lines, and a normal signal is generated;

[0077] The balance analysis module sends the normal signal or the abnormal signal to the display module, and the display module is used to display the abnormal signal or the normal signal of the dynamic balance test of the double-section rotor of the engine to be tested;

[0078] In this application, if corresponding calculation formulas appear, the above calculation formulas are all dimensionless and take their numerical calculations. The weight coefficients, proportional coefficients and other coefficients in the formulas are set to a result value obtained by quantifying each parameter. The size of the weight coefficient and the proportional coefficient can be determined as long as it does not affect the proportional relationship between the parameter and the result value.
