[0032] Figure 2 It is a flowchart of another control method provided in an embodiment of the present application. DETAILED DESCRIPTION
[0033] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. 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 creative work should fall within the scope of protection of the present application.
[0034] It should be understood that the "multiple" mentioned herein refers to two or more. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solution of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and the like are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not limit them to be necessarily different.
[0035] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.
[0036] During the development of air conditioners, it is necessary to conduct vibration tests on the compressor and various pipes or other components connected to the compressor during the test of air conditioner products to ensure the installation position of the compressor to avoid vibration and abnormal noise when the air conditioner is in use. However, the existing vibration test usually sets strain gauges on the air conditioner prototype. The air conditioner prototype here refers to the physical version made according to the design drawings or models after the air conditioner is completed in the design stage, which is used to verify the actual effect of the design scheme. The air conditioner prototype here can be a complete functional model or a partial model with a compressor and pipes connected to the compressor. By detecting stress and vibration, the vibration degree of the compressor is judged and the installation position of the compressor is adjusted to ensure the installation position of the compressor to reduce vibration and abnormal noise when the air conditioner is in use. However, installing strain gauges is time-consuming and labor-intensive. Taking a large commercial modular machine as an example, it has more compressors and pipes. In a vibration test, about 200 strain gauges are required for detection. The preparation work for the vibration test, such as welding, pasting and calibration of strain gauges, takes a long time and requires more manpower and material resources. It is difficult to ensure the accuracy of the vibration test results, which affects the development efficiency of the air conditioner and increases the development cost of the air conditioner.
[0037] According to a first aspect of the embodiment of the present disclosure, Figure 1 and Figure 2 As shown, a method for positioning a compressor is provided, wherein a gyroscope is provided on the compressor, and the positioning method comprises:
[0038] Step S100: Establish a first model in the simulation program. The first model is the model of the gyroscope when the compressor is not started. Since the gyroscope is set on the compressor, before the first model, it is usually necessary to set a basic model in the simulation program. The basic model here can be the model of the air conditioner prototype mentioned above in the simulation program. The basic model includes the model of the compressor itself when it is not started, and also includes the model of the gyroscope on the compressor when the compressor is not started. At this time, the posture of the gyroscope is the initial posture, that is, the first model, and also includes the model of the pipeline connected to the compressor and the model of other structures. Through the first model, a model foundation is provided for subsequent simulations.
[0039] Step S200: According to the first model, a second model is established through a simulation program. The second model is: a model of a gyroscope when the compressor is running at a first frequency. In the normal operating state, the compressor has its own specific frequency range. The frequency ranges of normal operating of compressors of different models are also different. According to different compressors, the first frequency can be arbitrarily selected as the first frequency within the frequency range of normal operating corresponding to the compressor, and the present disclosure does not make specific restrictions on this. The compressor can operate normally at the first frequency. In the simulation program, the normal operation of the compressor at the first frequency is used as the input excitation of the compressor. At this time, the operation of the compressor will be simulated in the simulation program, and then a new model will be established. This new model can become a first determination model. The first determination model can be understood as the balanced position of the compressor at the first frequency, and the vibration of the compressor at this position is small. The first determination model is based on the basic model mentioned above. The model obtained when the compressor operates normally at the first frequency. Compared with the basic model mentioned above, in the first determination model, the position of the compressor will change. Correspondingly, in the first determination model, the attitude of the gyroscope will change, that is, the gyroscope has an angular velocity input. In the first determination model, the model of the gyroscope is the second model.
[0040] Step S300: Obtain the attitude of the gyroscope in the second model through the simulation program, and adjust the position of the compressor according to the current signal of the second model, so that the attitude of the gyroscope after the compressor position is adjusted is consistent with the attitude of the gyroscope in the second model. The consistency mentioned here refers to the situation that the two are equal or the deviation between the two is within a preset range. Since the second model is obtained by the simulation program under an ideal environment, it is difficult to ensure that the attitude of the gyroscope after the compressor position is adjusted is equal to the attitude of the gyroscope in the second model when adjusting the position of the compressor in the air-conditioning prototype. Therefore, when adjusting the position of the compressor, a certain error can be allowed. As mentioned above, compared with the gyroscope in the first model, the attitude of the gyroscope in the second model will change. When the attitude of the gyroscope changes, a current signal will be output. The current signal of the second model can be obtained through the simulation program. After obtaining the current signal of the second model, according to the current signal of the second model, the position of the compressor in the above-mentioned air-conditioning prototype can be adjusted so that the current signal of the gyroscope after the compressor position is adjusted is equal to the current signal of the second model. The adjustment of the position of the compressor mentioned here is to adjust the position of the compressor in the air-conditioning prototype as mentioned above. In the air conditioner prototype, when the current signal of the gyroscope after the compressor position is adjusted is equal to the current signal of the second model, it means that in the air conditioner prototype, the position of the compressor corresponds to the position of the compressor in the simulation program when it is normally operating. In this way, when the compressor in the air conditioner prototype is started, the vibration of the compressor will be as close as possible to the position of the compressor in the simulation program when it is normally operating. In this way, the compressor uses the gyroscope as a reference and adjusts the compressor itself to the position when the compressor is normally operating through the simulation program. In this way, the vibration and noise of the compressor are reduced, and further, the vibration and abnormal noise of the air conditioner when in use are reduced.
[0041] Through the above technical solution, during the vibration test of the air conditioner prototype, a gyroscope is set on the compressor and the gyroscope is used as a reference. Through the simulation program, the posture of the gyroscope of the compressor during normal use is obtained. Based on the posture of the gyroscope of the compressor during normal use in the simulation program, the compressor itself is adjusted to the position of the compressor during normal operation. In this way, the vibration and noise of the compressor are reduced, and further, the vibration and abnormal noise of the air conditioner during use are reduced. Compared with the related art of setting strain gauges on the air conditioner prototype for vibration testing, the position of the compressor during normal use can be more accurately obtained through the simulation program and the gyroscope, ensuring the accuracy of the vibration test results. At the same time, through the vibration test of the air conditioner prototype by the simulation program and the gyroscope, the operator is no longer required to complete the welding, pasting and calibration of the strain gauge, etc., which reduces the time spent on the vibration test, reduces manpower and material resources, ensures the development efficiency of the air conditioner, and reduces the development cost of the air conditioner. At the same time, through accurate simulation calculation, the compressor load is identified, and then an effective pipeline stress simulation result is obtained to guide the pipeline design; and the gyroscope is used to regulate the vibration of the compressor to reduce the use of vibration reduction materials.
[0042] The gyroscope mentioned above can be set on a certain horizontal plane of the compressor in the air-conditioning prototype, so that the initial posture of the gyroscope can be adjusted to the zero position of the gyroscope. The zero position of the gyroscope usually refers to the output value of the gyroscope when there is no angular velocity input, that is, the gyroscope in the first model corresponds to the zero position of the gyroscope itself. In this way, when the second model is obtained, it is easier to obtain the current signal of the second model.
[0043] In some embodiments, step S300 may include step S301: obtaining the attitude of the gyroscope in the second model through a simulation program, obtaining the current signal of the second model according to the attitude of the gyroscope in the second model, and / or obtaining the moment of inertia J1 and angular momentum H1 of the equatorial axis of the gyroscope in the second model, and adjusting the position of the compressor according to the current signal of the second model and / or the moment of inertia J1 and angular momentum H1 of the equatorial axis of the gyroscope in the second model, so that the attitude of the gyroscope after the compressor position is adjusted is consistent with the attitude of the gyroscope in the second model. Taking a common gyroscope as an example, an equatorial axis is provided in the gyroscope. When the attitude of the gyroscope changes, that is, when the gyroscope has an angular velocity input, the gyroscope can output a current signal, and when the attitude of the gyroscope changes, the force on the equatorial axis of the gyroscope will change. By obtaining the force change on the equatorial axis, the moment of inertia J1 and angular momentum H1 of the equatorial axis can be obtained. In this way, the position of the compressor is adjusted according to the moment of inertia J1 and angular momentum H1 of the equatorial axis, or the position of the compressor is adjusted according to the current signal output by the gyroscope in the second model. In this way, compared with directly adjusting the position of the compressor, by first obtaining the force change on the equatorial axis of the gyroscope or the change in the current signal, the position of the compressor can be adjusted more accurately, thereby ensuring the accuracy of the adjusted compressor position.
[0044] Specifically, the moment of inertia J1 and the angular momentum H1 of the equatorial axis can be obtained according to the current signal output by the gyroscope. Correspondingly, the current signal output by the gyroscope can also be obtained according to the moment of inertia J1 and the angular momentum H1 of the equatorial axis.
[0045] In some embodiments, when the position of the compressor is adjusted according to the moment of inertia J1 and angular momentum H1 of the equatorial axis, the moment of inertia J1 and angular momentum H1 of the equatorial axis of the gyroscope in the second model can be obtained first. As described above, the moment of inertia J1 and angular momentum H1 can be correlated with the current signal. At this time, the current signal of the second model can be obtained according to the moment of inertia J1 and angular momentum H1, and then the position of the compressor is adjusted according to the current signal of the second model, so that the current signal of the gyroscope after the compressor position is adjusted is equal to the current signal of the second model or the deviation between the two is within a first preset range, thereby further ensuring the accuracy of the compressor position after adjustment.
[0046] In other embodiments, when the position of the compressor is adjusted according to the current signal of the second model, the current signal of the second model can be obtained, and the moment of inertia J1 and angular momentum H1 of the equatorial axis of the gyroscope in the second model can be obtained according to the current signal. Then, according to the moment of inertia J1 and angular momentum H1, the position of the compressor is adjusted, so that the moment of inertia and angular momentum of the equatorial axis of the gyroscope after the compressor position is adjusted are equal to the moment of inertia J1 and angular momentum H1, or the deviation is within a second preset range, thereby further ensuring the accuracy of the compressor position after adjustment.
[0047] At the same time, in some other embodiments, the two embodiments mentioned above can be adopted at the same time, so that the adjusted positions of the two compressors can be obtained, and based on the adjusted positions of the two compressors, the accuracy of the adjusted compressor positions can be further guaranteed.
[0048] The positioning method in the present application also includes step S400: obtaining the force F at the center of mass and the torque M at the center of mass when the compressor is running at the first frequency; step S200 may include step S201: according to the force F, the torque M and the first model, the force F and the torque M are used as the input excitation of the first model, and a second model is established through a simulation program, and the second model is: a model of the gyroscope when the compressor is running at the first frequency. The center of mass is the abbreviation of the center of mass, and the center of mass of the compressor can be understood as a point where the mass of the compressor is concentrated. By obtaining the force F at the center of mass and the torque M at the center of mass when the compressor is running at the first frequency, the state of the compressor when it is running at the first frequency can be accurately obtained, and then the force F and the torque M are used as the input excitation of the first model, and a second model is established through a simulation program. The force F and torque M here serve as the input excitation of the first model, which can be understood as the force F and torque M serving as the input signals of the first model in the simulation program. In this way, with the force F and torque M as input signals, the above-mentioned first determination model can be obtained more accurately. Furthermore, the second model can also be more accurate, further ensuring the accuracy of the positioning method of the compressor in the present application.
[0049] In some embodiments, in step S201, the vibration acceleration of the compressor cylinder when it is running at the first frequency can be obtained, and the rotational acceleration of the compressor cylinder when it is running at the first frequency can be obtained according to the vibration acceleration, and the center of mass acceleration of the compressor cylinder when it is running at the first frequency can be obtained according to the rotational acceleration, and the force F at the center of mass and the torque M at the center of mass when the compressor is running at the first frequency can be obtained according to the center of mass acceleration. In this way, by obtaining the vibration acceleration and calculating the rotational acceleration and the center of mass acceleration in sequence, the center of mass acceleration when the compressor cylinder is running at the first frequency can be obtained, and finally the force F at the center of mass and the torque M can be calculated.
[0050] Specifically, 3N measuring points may be provided on the compressor cylinder, where N is a positive integer, and N is greater than or equal to 1, and the vibration acceleration of the 3N measuring points when the compressor cylinder is running at the first frequency is obtained; based on the vibration acceleration of every three measuring points when the compressor cylinder is running at the first frequency, the rotational acceleration of the N compressor cylinders when running at the first frequency is obtained; based on the rotational acceleration of the N compressor cylinders when running at the first frequency, the center of mass acceleration of the N compressor cylinders when running at the first frequency is obtained; based on the center of mass acceleration of the N compressors when running at the first frequency, the sub-force F1 at the center of mass and the sub-torque M1 at the center of mass of the N compressors when running at the first frequency are obtained; the average value of multiple forces F1 is the force F, and the average value of multiple sub-torques M1 is the torque M. For every three test points, the rotational acceleration of a compressor cylinder when running at the first frequency can be obtained by measurement. Taking test point 1, test point 2 and test point 3 as examples, the vibration accelerations of test point 1 in three directions obtained by measurement are respectively The vibration accelerations of test point 2 in three directions are measured and obtained respectively: The vibration accelerations of test point 3 in three directions are measured and obtained respectively: The rotation acceleration of the compressor cylinder in three directions when running at the first frequency is obtained through the vibration acceleration of the three test points in three directions. The three rotation accelerations can be respectively understood as the radial acceleration of the cylinder body, the tangential acceleration of the cylinder body and the normal acceleration of the cylinder body. Specifically, the formula shown in Formula 1 in FIG.
[0051]
[0052] In formula 1, the rotational acceleration that needs to be calculated is removed. There are two matrices on both sides of the equal sign. The matrix on the left side of the equal sign represents the acceleration vector difference between test point 1 and test point 2, and the matrix on the right side of the equal sign represents the position coordinate difference between test point 1 and test point 2. The rotational acceleration can be calculated through the two test points. At this time, the value of test point 3 is used to correct the obtained rotational acceleration. The rotational acceleration can be calculated again through test point 3 and test point 1, and compared with the rotational acceleration calculated through test point 1 and test point 2 to ensure the accuracy of the calculated rotational acceleration.
[0053] The rotational accelerations in three directions of the compressor cylinder body when running at the first frequency are obtained. According to the formula in Figure 2, the center of mass acceleration can be calculated
[0054]
[0055] Based on the calculated center of mass acceleration According to the formula in Formula 3 and the formula in Formula 4, the center-of-mass force F1 and the center-of-mass torque M1 are finally calculated.
[0056]
[0057] By measuring, the rotational acceleration of a compressor cylinder body when it runs at the first frequency can be obtained, and the rotational acceleration of a compressor cylinder body when it runs at the first frequency can be calculated. By calculating, the center of mass acceleration of N compressor cylinder bodies when they run at the first frequency can be calculated, and the center of mass force F1 and center of mass torque M1 of a compressor when it runs at the first frequency can be calculated. When 3N measuring points are set on the compressor cylinder body, the center of mass force F1 and center of mass torque M1 of N compressors running at the first frequency can be calculated. According to the center of mass force F1 and center of mass torque M1 of N compressors running at the first frequency, more accurate force F and torque M can be obtained. In this way, when force F and torque M are used as input signals, the above-mentioned first determination model can be obtained more accurately. Further, the second model can also be more accurate, which further ensures the accuracy of the positioning method of the compressor in the present application.
[0058] Furthermore, the 3N measuring points can be respectively arranged on the same plane of the outer surface of the compressor cylinder body. In this way, when each test point is subjected to vibration acceleration, the direction of the vibration acceleration of each test point corresponds to each other, which is more convenient for calculating the rotation acceleration.
[0059] As described above, in the normal operating state, the compressor has its own specific frequency range. The normal operating frequency ranges of compressors of different models are also different. Depending on the compressor, the first frequency can be arbitrarily selected from the normal operating frequency range of the compressor as the first frequency. Generally speaking, the normal operating frequency range of the compressor is generally between 20Hz and 100Hz. At this time, the first frequency can be greater than or equal to 20Hz and less than or equal to 100Hz. That is, the first frequency can range from 20Hz to 100Hz.
[0060] According to a second aspect of an embodiment of the present application, an electronic device is provided, including a memory and a controller, wherein the memory is used to store a computer program; and the controller is used to execute the computer program to implement the steps of any one of the above-mentioned compressor positioning methods.
[0061] According to a third aspect of an embodiment of the present application, a compressor is provided, on which a gyroscope is provided, and the compressor is used to execute any one of the above-mentioned compressor positioning methods, or further includes an electronic device as described above.
[0062] In some embodiments, a plurality of gyroscopes are provided, and the plurality of gyroscopes are respectively provided on the legs of the compressor. The legs can fix and support the compressor. When the gyroscopes are provided on the legs, the position of the compressor during normal use can be more accurately obtained. At the same time, when the compressor applies the positioning method of the compressor, a plurality of second models are obtained through a plurality of gyroscopes, and current signals of the plurality of second models are obtained. Through the current signals of the plurality of second models, the compressor itself can be more accurately adjusted to the position during normal operation of the compressor, thereby reducing the vibration and noise of the compressor, and further reducing the vibration and abnormal noise of the air conditioner during use.
[0063] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
