301. And acquiring a first resonant frequency corresponding to the first motor.
The resonant frequency of the first motor is obtained, and when resonance occurs, the resonant circuit amplifies the input by several times, so that the vibration intensity of the motor is the maximum at this time, specifically, the first resonant frequency can be obtained through a vibration intensity-frequency graph corresponding to the first motor (i.e., a capacity graph corresponding to the first motor), and the vibration frequency with the highest vibration intensity among the vibration frequencies is the resonant frequency, and a specific resonant frequency obtaining manner may be determined according to an actual situation, which is not limited herein.
302. And acquiring a second resonant frequency corresponding to the second motor.
A second resonant frequency corresponding to the second motor is obtained, and the obtaining manner of the second resonant frequency is similar to the obtaining process of the resonant frequency corresponding to the first motor, and details are not repeated here. It should be noted that, the present embodiment is described by taking the determination of the relationship between the vibration effects of two motors as an example, but the present embodiment may also be implemented by a plurality of motors without being limited to two, and the specific number may be determined according to the actual situation, and is not limited herein.
303. And judging the relation between the frequency difference value between the first resonant frequency and the second resonant frequency and the first preset value.
Specifically, a difference between the first resonant frequency and the second resonant frequency is calculated, the difference is referred to as a frequency difference for short, and a relationship between the frequency difference and a first preset value is determined, where the first preset value is preset by a worker, and the value may be determined according to an actual situation, and is not limited herein. If the frequency difference is smaller than or equal to the first preset value, it is determined that the frequency difference between the peak values of the vibration intensities of the first motor and the second motor is small, and the vibration effects of the first motor and the second motor are relatively similar to each other along with the change of the vibration frequency, and it can be determined that the vibration effects of the first motor and the second motor at the same vibration frequency are the same, that is, step 304 is performed to determine that the vibration effects of the first motor and the second motor at the same vibration frequency are the same. If the frequency difference is greater than the first preset value, it indicates that the difference between the vibration effects of the first motor and the second motor is large along with the change of the vibration frequency, step 305 is executed to obtain a first resonance intensity corresponding to the first resonance frequency and a second resonance intensity corresponding to the second resonance frequency.
304. And determining that the vibration effects of the first motor and the second motor are consistent under the same vibration frequency.
If the frequency difference between the first resonant frequency and the second resonant frequency is less than or equal to the first preset value, it is indicated that the difference between the resonant frequencies of the first motor and the second motor is relatively small, specifically, refer to fig. 4, where fig. 4 is a schematic diagram of a possible vibration intensity-frequency curve of the first motor and the second motor, and at this time, the trend of the capability curve of the first motor and the trend of the capability curve of the second motor are relatively similar, so that it can be determined that the vibration effects of the first motor and the second motor under the same vibration frequency are the same, and in an actual implementation process, the vibration effect can be determined based on a certain range, for example, it is determined that the same vibration effect is output by a part of the first motor and the second motor within a dashed frame in fig. 4. The specific manner can be determined according to actual conditions, and is not limited herein.
305. And acquiring a first resonance strength corresponding to the first resonance frequency and a second resonance strength corresponding to the second resonance frequency.
If the frequency difference between the first resonant frequency and the second resonant frequency is smaller than or equal to the first preset value, it is indicated that the difference between the resonant frequencies of the first motor and the second motor is relatively large, and the relationship between the vibration effects of the motors is determined by the disagreement of the frequency dimensions, so that the corresponding resonant strength of the first motor and the second motor under the condition of the resonant frequencies needs to be further obtained, and further analysis is performed based on the information of the resonant strength. The specific resonance intensity corresponding to each of the first motor and the second motor can be obtained by the intensity curve corresponding to each motor, which can be determined according to the actual situation, and is not limited herein.
306. And judging the relation between the intensity difference value between the first resonance intensity and the second resonance intensity and a second preset value.
Specifically, a difference between the first resonance intensity and the second resonance intensity is calculated, the difference is referred to as an intensity difference for short, and a relationship between the intensity difference and a second preset value is determined, wherein the second preset value is preset by a worker, and the value can be determined according to an actual situation, which is not limited herein. If the intensity difference is less than or equal to the second preset value, it indicates that the actually achievable intensity peak values of the first motor and the second motor are approximate, and it can be determined that the vibration effects of the first motor and the second motor are consistent under the condition that the vibration intensities are consistent, that is, step 307 is executed to determine that the vibration effects of the first motor and the second motor are consistent under the same vibration intensity. If the difference between the intensities is greater than the second preset value, it indicates that there is a large difference between the resonant frequencies of the first motor and the second motor, and step 308 is executed to determine the relationship between the vibration effects of the first motor and the second motor based on the vibration intensity and the vibration frequency of the first motor and the vibration intensity and the vibration frequency corresponding to the second motor.
307. And determining that the vibration effects of the first motor and the second motor are consistent under the same vibration strength.
If the frequency difference between the first resonance strength and the second resonance strength is less than or equal to the second preset value, it is indicated that the difference between the resonance strengths of the first motor and the second motor is small, specifically, refer to fig. 5, where fig. 5 is another possible schematic diagram of vibration strength-frequency curves of the first motor and the second motor, at this time, the difference between the trend of the capability curve of the first motor and the trend of the capability curve of the second motor in the frequency direction is large, but the difference between the maximum strengths (i.e., resonance strengths) that the two can reach is small, so that it can be determined that the vibration effects of the first motor and the second motor under the same vibration strength are the same, and in the actual implementation process, the vibration effect can also be determined based on a certain range, for example, it is determined that the vibration effects of part of the first motor and the second motor within the dashed frame in fig. 5 are the same.
308. Determining a vibration effect relationship of the first motor and the second motor based on the vibration intensity and the vibration frequency of the first motor and the vibration intensity and the vibration frequency corresponding to the second motor
Specifically, if the frequency difference between the first resonance strength and the second resonance strength is greater than the second preset value, it is indicated that a large difference exists between the resonance frequency and the resonance strength of the first motor and the second motor, specifically, referring to fig. 6, fig. 6 is a schematic diagram of another possible vibration strength-frequency curve of the first motor and the second motor, it can be seen that the difference between the capability curve of the first motor and the capability curve of the second motor is large, at this time, the vibration effect relationship between the first motor and the second motor can be determined by comprehensively considering the vibration strength and the vibration frequency, specifically, when the vibration effects of the first motor and the second motor are determined to be consistent, the vibration strength difference and the vibration frequency difference between the first motor and the second motor should be ensured to be small as much as possible, obviously, when the vibration effects are determined to be consistent, a specific relationship determination strategy is determined based on the selection of a user, for example, the vibration frequency difference occupies a high weight when the vibration effect relationship is determined, the vibration intensity difference is weighted lower, that is, the vibration effects of the first motor and the second motor in the dashed line box are determined to be consistent as shown by the dashed line box 1 in fig. 6, or the vibration intensity difference is weighted higher and the vibration frequency difference is weighted lower when the vibration effects are related, that is, the vibration effects of the first motor and the second motor in the dashed line box are determined to be consistent as shown by the dashed line box 2 in fig. 6. The specific vibration effect determination manner may be determined according to actual situations, and is not limited herein.
