Description

Technical Field

[0001] This invention belongs to the field of aero-engine test data processing technology, and particularly relates to a real-time processing method, device and medium for comprehensive margin and maximum stability margin. Background Technology

[0002] For fans or compressors, margin represents the range within which they can deviate from their operating line while still functioning normally. Margin is based on a point on the operating line and represents the maximum range within which the compressor or fan can deviate from the operating point without experiencing unstable conditions such as surge or stall. For constant-speed characteristic curve recording tests of fans or compressors, both pressure ratio and flow rate change from the operating point to the surge or stall point. Using pressure ratio margin or flow rate margin alone cannot adequately reflect the compressor's margin; a combined margin is generally used. However, the reference point for calculating the combined margin is the intersection of the constant-speed characteristic curve and the operating line, which cannot be predicted in advance and must be determined during the constant-speed characteristic curve recording process. Therefore, conventional fan or compressor surge margins are calculated through post-test processing, making it impossible to monitor the fan or compressor margin in real-time during the test. Furthermore, there are lacking methods for selecting and generating test data before surge or stall (i.e., the maximum surge margin point). Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art in that it is impossible to grasp the overall margin and maximum stability margin of the fan or compressor in real time during the test, and to provide a method, device and medium for real-time processing of overall margin and maximum stability margin.

The converted flow rate corresponding to the state point is used as... .

[0016] Preferably, the preset range is [-0.5%, +0.5%].

[0017] Preferably, step S1 includes:

[0019] Alternatively, after recording the stable state point of the common working line, obtain... and .

[0020] Preferably, step S2 includes:

[0021] The selection of the highest steady-state performance point is based on key characteristic performance parameters, which include the converted flow rate, torque, pressure ratio, rotational speed, and temperature rise efficiency of the test specimen.

[0022] Preferably, step S2 includes:

[0023] If the stabilization time of the key feature performance parameters exceeds the preset threshold, then step S201 is executed.

[0025] Step S202: If a short circuit occurs within the (i+1)th preset period, the first average value is used as the characteristic parameter corresponding to the maximum stability comprehensive margin operating condition point; if a short circuit does not occur within the (i+1)th preset period, i+1 is assigned to i, and the process returns to step S201.

[0026] Where i∈[1,N], and N is a positive integer greater than 1.

[0027] Ideally, the preset threshold is 3-10 seconds.

[0028] The present invention also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the real-time processing method of the present invention for comprehensive margin and maximum stability margin.

[0040] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0041] Example 1

[0042] This embodiment provides a real-time processing method for comprehensive margin and maximum stability margin. (Refer to...) Figure 1 The real-time processing method for the comprehensive margin and maximum stability margin includes the following steps:

[0043] Step S1: Obtain the real-time comprehensive margin based on the constant rotational speed reference point, real-time pressure ratio, and real-time converted flow rate.

[0044] Step S2: Obtain the maximum stable overall margin in real time.

[0045] In specific implementation, in step S1, the constant rotation speed reference point, real-time pressure ratio, and real-time converted flow rate are obtained during the test. The real-time converted flow rate pressure ratio margin (i.e., real-time pressure ratio margin) is obtained according to Formula 1:

[0046] (Formula 1)

[0047] The real-time constant speed comprehensive margin is obtained according to Formula 2:

[0048] (Formula 2)

[0049] in, Characterizes the real-time equivalent flow rate pressure ratio margin. Characterizes the real-time constant speed comprehensive margin. The pressure ratio at a point on the common working line under the same flow rate is obtained by real-time flow rate interpolation of the common working line. Characterizes the linear pressure ratio of lines operating at constant speeds. Characterizes the converted flow rate of a common working line with constant rotational speed; Characterizing the real-time pressure ratio, It represents the real-time calculated flow rate. Figure 2 The above variables are illustrated.

[0050] Obtaining the real-time equivalent flow rate and pressure ratio margin effectively monitors the degree to which the current compressor state point deviates from the common operating line. Since the fan or compressor test state may be below the design operating line, the real-time pressure ratio margin can be negative. During the process of recording the constant speed performance characteristic lines, by adjusting the exhaust back pressure to move the fan or compressor test state from near-blockage to surge point, when the real-time pressure ratio margin is within ±0.5% of the threshold (this threshold is selected with the same adjustment accuracy as the test apparatus and can be adjusted as needed), this state point can be determined as the reference point for calculating the constant speed comprehensive margin, i.e., the constant speed reference point. The steady-state pressure ratio and equivalent flow rate under this state are then assigned to... and Afterwards, the exhaust back pressure is adjusted to bring the test state closer to the surge boundary. Using the real-time pressure ratio and real-time converted flow rate, the real-time constant speed comprehensive margin can be obtained according to Formula 2.

[0051] As an optional implementation method, refer to Figure 3 The process shown obtains the real-time constant speed comprehensive margin.

[0052] and The numerical value, i.e., determining whether the pressure ratio margin is within the preset threshold range, can be obtained either before or after the common working line stable state point is recorded. Here, the concept of a common working line intersection switch flag, named WL_Scan, is introduced.

[0053] Reference Figure 3 In one optional implementation, after the test begins and a new test speed is reached, if the flag (Y) is selected before the steady-state recording point, it is either manually checked or SM_PR meets the judgment condition, setting WL_Scan to 1. That is, either manually checking or establishing a channel for conditional judgment (when the pressure ratio margin is within a preset threshold) sets WL_Scan to 1. Then, clicking the "Record Steady-State Point" button illuminates the indicator light, indicating that a steady-state point of a common operating line at constant speed is recorded. This point serves as a reference point for calculating the comprehensive margin at constant speed, i.e., the constant speed reference point, and is assigned a value. and Numerical value. If the stable state point time has not reached (N), the process is manually canceled or automatically terminated, setting WL_Scan to 0. Then, this state point is discarded, and an incomplete record is displayed. and It remains the common operating line point of the previous rotational speed. That is, if other events occur during the recording of the common operating line stable state, causing the pressure ratio margin to deviate from the preset range or the test piece to experience abnormal vibrations, uncheck the WL_Scan flag and set it to 0, thus releasing the stable state point. and The assignment process is completed, and a message is displayed indicating that the current recording is not yet finished. Then, the process returns to the step of selecting the flag bit before choosing whether to record the steady-state point. Correspondingly, if the steady-state point time (Y) is reached, the indicator light goes out, and the common working line voltage ratio at this speed is obtained. Common working line conversion flow rate Then, continue the experiment, manually or by exceeding the judgment condition range, to make WL_Scan 0, and display the comprehensive margin SM at this speed in real time; then, return to the step of selecting the flag bit before selecting whether to record the steady-state point.

[0054] If a flag (N) is selected after steady-state recording, click the "Record Steady-State Point" button to complete the recording. Then, determine if SM_PR is within the preset range. That is, immediately after recording the steady-state point, determine if the pressure ratio margin is within the preset threshold (manual or automatic determination upon channel establishment). If it is (Y), set WL_Scan to 1, using this as a flag, and assign the pressure ratio and converted flow amplitude of this steady-state point to... , That is, if SM_PR is within the preset range (Y), then this point is considered a common working line intersection, WL_Scan is set to 1, and the pressure ratio and converted flow rate of this state point are assigned to [the appropriate value]. and Then, the experiment continues, displaying the overall margin SM at this speed in real time. Then, return to the step of selecting the flag before recording the steady-state point. If SM_PR is not within the preset range (N), the experiment continues, displaying the overall margin calculated from the intersection point of the common working line that meets the previous SM_PR preset range condition. That is, if SM_PR is not within the preset range (N), then WL_Scan is 0. and The value remains unchanged. Then, return to the step of selecting the flag bit before choosing whether to record the steady-state point.

[0055] In step S2, the maximum stability margin is obtained in real time. The selection of the maximum stability margin, or the surge-prone steady-state performance point, is based on the following: Analysis of test data from multiple fan compressors reveals that surge is often accompanied by significant fluctuations in parameters such as converted flow rate, torque, pressure ratio, speed, and temperature rise efficiency. Therefore, these five key parameters of the test specimen are selected as the basis for selecting the highest steady-state performance point. Furthermore, test equipment typically employs methods such as adjusting the exhaust valve and VSV (Variable Stator Vane) to force the test specimen into surge. Therefore, the exhaust valve position and VSV position of the test equipment are selected as two sets of parameters as the basis for selecting the surge-prone steady-state performance point. (Refer to...) Figure 4Specifically, when surge occurs, after the last operation of the test equipment, if all five key parameters have a stabilization time of more than 5 seconds, the average value of the stable state points over a period of time (recommended to be no less than 5 seconds) is recorded as the maximum state point. If surge or other problems occur within the stabilization time, the average value of the stable state points is calculated using data from the stabilization period before the last operation (no less than 5 seconds). The overall stability margin that the test piece can achieve is acquired and recorded in real time until the maximum overall stability margin obtained before the surge occurs, representing the maximum overall stability margin of the test piece under that operating condition (speed, VSV).

[0056] Specifically, the method for obtaining the real-time maximum comprehensive margin is as follows: Based on previous tests, especially in the high-speed surge test, it was found that after the last operation of the test equipment, the test piece would exhibit a phenomenon of "sudden surge and stall after a period of stabilization". However, this stabilization time is unpredictable. If the stabilization point is collected 1-2 minutes after the original test plan, the maximum stability comprehensive margin value within the stabilization period of the last operation will be missed.

[0057] Therefore, this embodiment proposes to directly obtain the maximum stable synthesis margin online. For specific implementation, refer to... Figure 7 Step S2 includes the following steps:

[0058] If the stabilization time of the key characteristic performance parameter exceeds a preset threshold, then step S201 is executed;

[0059] Step S201: Obtain the first mean. The first mean is the average value of the key characteristic performance parameters within the i-th preset period. Specifically, the average values ​​are obtained for the converted flow rate, torque, pressure ratio, speed, and temperature rise efficiency.

[0060] Step S202: If shortness of breath occurs within the (i+1)th preset cycle, proceed to step S203; if shortness of breath does not occur within the (i+1)th preset cycle, proceed to step S204.

[0061] Step S203: Use the first mean as the characteristic parameter corresponding to the operating point with the maximum stability comprehensive margin.

[0062] Step S204: Assign i+1 to i and return to step S201.

[0063] Where i∈[1,N], and N is a positive integer greater than 1. That is, starting from the first preset period, the process proceeds step by step until the feature parameters are obtained.

[0064] As an optional implementation, after all five key parameters have stabilized for more than 5 seconds, the average value of the key characteristic performance parameters is first calculated within a first specific time period T (preset period) (the value of T is customizable, but it is recommended to be no less than 5 seconds). If there is still no stabilization within the second time period T, the average value calculated in the second time period T is overwritten by the first average value. If there is stabilization within the second time period T, the average value within the first time period T is the characteristic parameter corresponding to the maximum stability comprehensive margin operating condition point; and so on. Figure 5 This illustrates the scenario where surge occurs within the first T-interval. The stable state point taken before the equipment's last operation is defined as FS1. If there is a stabilization period of more than 5 seconds after the last operation, the stable state point FS2 within the first T-interval is recorded. If surge or other problems occur during this period, FS1 is the maximum overall margin point. If FS2 is successfully completed within the first T-interval, FS2 is designated as the maximum overall margin point. The time-averaged recording of the stable state point FS3 in the second T-interval is then initiated. If surge or other problems occur during this period, FS2 is designated as the maximum overall margin point; otherwise, FS3 is designated as the maximum overall margin point. This process continues until the time-averaged value of the last stable state point recorded before the surge is determined as the maximum overall margin point. Figure 6 This illustrates the case where surge occurs within the third T interval.

[0065] Regarding the above methods, such as Figure 8 As shown, this embodiment provides an implementation method. The HMI (Human-Machine Interface) module is responsible for selecting or setting the conditions for determining the common operating point at constant speeds and displaying them; triggering the buffer signal; triggering the surge relief signal; displaying the comprehensive margin at constant speeds; and displaying the stable state point (maximum stability margin).

[0066] The data processing module is responsible for processing real-time acquired data / calculated data / events. If the buffer signal (Y) has been triggered 5 seconds after the last sequential action of the test equipment and before the status recording, it determines whether a reversal signal has been triggered during the status recording process. If not (N), the status point memory data is updated; if yes (Y), the status point memory data remains unchanged and is then saved to a file. If the buffer signal (N) has not been triggered 5 seconds after the last sequential action of the test equipment and before the status recording, the data is directly saved to a file. In other words, the data processing module performs logical judgment processing, focusing on the operating condition 5 seconds after the last action of the test equipment has stabilized: if the buffer signal has been triggered before the status point recording, but no reversal has occurred during the acquisition process, the status point data is first cached in memory as the maximum comprehensive margin point to be determined before the next status acquisition; otherwise, the previous working status point is maintained and saved to a file as the final result of the maximum comprehensive margin point.

[0067] The data acquisition module is responsible for acquiring analog quantities such as temperature, pressure, and torque.

[0068] The real-time processing method for comprehensive margin and maximum stability margin in this embodiment proposes to use an online determination and recording method for pressure ratio margin to obtain the average value under a certain time period as the intersection point of the performance characteristic line and the common working line at this speed, and use it as the reference point for constant speed. Thus, the real-time comprehensive margin can be obtained by using the real-time pressure ratio and the real-time converted flow rate.

[0069] The real-time processing method for comprehensive margin and maximum stability margin in this embodiment defines the selection criteria and method for maximum surge margin, and obtains the maximum stability comprehensive margin in real time by combining the trigger buffer signal and the surge relief signal.

[0070] According to the real-time processing method for comprehensive margin and maximum stability margin in this embodiment, the comprehensive margin at constant speed is calculated and the maximum margin is obtained in real time during the test, which can significantly reduce the manual post-processing time. For some high-load test specimens, or for the safety of the test specimens, designers do not want the fan or compressor to surge, but only want to record performance at a specific comprehensive margin. The real-time acquisition of the comprehensive margin at constant speed can greatly reduce the manpower and resource consumption costs of repeated test iterations and improve the success rate of a single test.
