Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0040] Figure 4 It is a structural schematic diagram of a computer device in one embodiment of the present invention. DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present invention, not 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.

[0042] Since human hearing is approximately linearly related to the dB of sound, the acoustic performance is expressed in dB, while the price and weight are assumed to be expressed in yuan and kilograms respectively, such as Figure 1 As shown in the figure, it is a three-dimensional scatter plot of the acoustic performance, price and weight of a certain acoustic material, where X represents the acoustic performance (such as sound insulation), Y represents the price (i.e., the cost), and Z represents the weight. It can be seen that in the three-dimensional graph, it is necessary to find the solution with the best performance, the lowest weight, and the lowest price. However, the price and weight of the solution with the best performance are not necessarily the lowest. Therefore, the traditional solution only considers a single factor and is not convenient for finding a suitable acoustic material. Therefore, it is necessary to propose a comprehensive performance index to guide the material selection of the product.

[0043] The embodiments of the present application mainly provide a method for calculating the comprehensive performance of acoustic materials. The method is applied to the comprehensive performance evaluation of acoustic materials in various automobile development processes, and can also be applied to the comprehensive evaluation of acoustic materials in other product development processes, without specific limitation. The embodiments of the present application provide a new method for calculating the comprehensive performance of acoustic materials, which can bring a new idea of ​​comprehensive evaluation to product development manufacturers. Among them, its method for calculating the comprehensive performance of acoustic materials has a different idea from the existing calculation method. The following is a detailed description of the method for calculating the comprehensive performance of acoustic materials provided by the present invention through various embodiments.

[0044] In this embodiment, if Figure 2 As shown, a method for obtaining acoustic material performance is provided, which mainly includes the following steps:

[0045] S10: Obtain the acoustic performance, price and weight of the target acoustic material;

[0046] Traditional solutions only consider price or weight. The embodiments of the present application will obtain the acoustic performance, price and weight of the target acoustic material when evaluating the comprehensive performance of the target acoustic material. Among them, the target acoustic material represents one of the candidate acoustic zero materials in the product to be developed. For example, taking the product to be developed as an automobile product as an example, when developing automobile products, the acoustic materials used in systems such as floor systems must consider their comprehensive performance. For example, for sound-absorbing panels, the goals pursued by different developers are different. Based on the differences, it is impossible to evaluate whether the current target acoustic material is suitable only by relying on acoustic performance or cost. Therefore, the embodiments of the present application will obtain the acoustic performance, price and weight of the target acoustic material for subsequent comprehensive evaluation.

[0047] Among them, the acoustic performance is used to characterize the acoustic performance of the target acoustic material, including sound absorption and / or sound insulation performance, etc. As an example, the acoustic performance is obtained in the following way: obtaining the insertion loss and sound absorption coefficient of the target acoustic material; obtaining the acoustic performance according to the insertion loss and sound absorption coefficient of the target acoustic material.

[0048] Specifically, the acoustic performance of the acoustic material can be expressed by the formula SAIL=IL+10log(α), where the insertion loss of the acoustic material is IL and the sound absorption coefficient of the acoustic material is α. The larger the value of SAIL, the better the acoustic performance of the acoustic part material.

[0049] It should be noted that the above formula is only one of the ways to calculate the acoustic performance of an acoustic material, and is not specifically limited. For example, the acoustic performance may also be an acoustic performance parameter obtained by an acoustic material manufacturer through testing and calibration.

[0050] In one embodiment, in a specific application, an acoustic material database is established and maintained, and the acoustic material database includes specific data in three dimensions: acoustic performance, price, and weight of the acoustic material. The materials in the acoustic material database are respectively identified by the three dimensions of acoustic performance, price, and weight, as shown in Table 1:

[0051] Table 1

[0052]

[0053]

[0054] As shown in Table 1, materials 1-8 represent several acoustic materials of target components in the developed product, and each acoustic material has corresponding acoustic performance, price and weight parameters. When the performance parameters of the target acoustic material need to be evaluated, the acoustic performance, price and weight data of the corresponding material can be directly retrieved from the acoustic material database using the dimension identifier, so as to facilitate the evaluation of the performance parameter indicators.

[0055] S20: Acquire a conversion constant between the weight and the price;

[0056] S30: Determine the performance parameters of the target acoustic material according to the conversion constant, acoustic performance, price and weight.

[0057] It should be understood that for a single acoustic material, if the weight is doubled, the sound insulation will increase by 6dB, that is, the acoustic performance will be improved accordingly. It can be seen that there is a corresponding relationship between weight and acoustic performance, and there is also a conversion relationship between the weight of the acoustic material and the price. The embodiment of this application is represented by a conversion constant k, which can be customized by the product development manufacturer. Therefore, after obtaining the conversion relationship between weight and price, the performance parameters of the target acoustic material can be comprehensively determined based on the conversion constant, acoustic performance, price and weight, which are used to characterize the comprehensive performance of the target acoustic material to guide product development.

[0058] It can be seen that in this embodiment, a method for obtaining the performance of acoustic materials is provided. Through the relationship between the acoustic performance, price and weight of the acoustic material, the performance parameters used to characterize the comprehensive performance of the target acoustic material are comprehensively determined, and the comprehensive performance indicators of the acoustic material are redefined to provide a basis for reducing weight and cost for product project development, which has high practicality.

[0059] It should be noted that, in the process of determining the performance parameters of the target acoustic material according to the conversion constant, acoustic performance, price and weight, the embodiment of the present application provides two corresponding processing methods, which are introduced below respectively.

[0060] In one embodiment, in step S30, that is, determining the performance parameter according to the conversion constant, acoustic performance, price and weight, includes:

[0061] S31A: Obtaining a sum of the conversion constant and the weight, and calculating a logarithm of a ratio of the price to the sum to obtain a first logarithm;

[0062] S32A: Determine the performance parameter according to the first logarithm and the acoustic performance.

[0063] Specifically, the calculation method is to determine the performance parameters through the following formula:

[0064]

[0065] Wherein, q represents the performance parameter, p represents the performance comparison empirical coefficient, log10(y / k+z) represents the first logarithm, y represents the price, z represents the weight, k represents the conversion parameter, and SAIL represents the acoustic performance.

[0066] It should be noted that p represents the performance comparison empirical coefficient, which is an empirical coefficient. For example, p can be 20, and there is no specific limitation. At this time, the performance parameter can be transformed into:

[0067]

[0068] In this embodiment, when calculating the comprehensive performance of the acoustic material, it will be calculated according to the needs of the product development manufacturers. Different product development manufacturers have different requirements for the performance, price and weight of the acoustic materials. Some product development manufacturers pay more attention to performance, some product development manufacturers pay more attention to quantity, and some product development manufacturers pay more attention to price. In this embodiment, the conversion relationship between the three is used to calculate a quantitative value in a quantitative manner to characterize the comprehensive performance of the target acoustic material, and a performance ratio of a comprehensive indicator is obtained as a performance parameter, which is more valuable for reference than simply considering a single factor such as weight or price.

[0069] It should be noted that the above calculation formula is only one form of calculation, and a reciprocal conversion may also be used instead of calculating a ratio, and a constant representing the performance parameter may also be obtained, without specific limitation.

[0070] It should also be noted that in the embodiments of the present application, different product development manufacturers may have different emphases on price, weight and acoustic performance. Therefore, in order to find the balance between different performances, different prices and different weights for different manufacturers, the performance parameters of the target acoustic material can be calculated by matching the weights of the three to better match the purpose of the product development manufacturer.

[0071] Specifically, in one embodiment, in step S30, the performance parameters are determined by converting constants, acoustic performance, price and weight, and specifically include the following steps:

[0072] S31B: assign corresponding weights to price, weight and acoustic performance respectively;

[0073] In one embodiment, the respectively assigning corresponding weights to the price, the weight and the acoustic performance includes: assigning corresponding weights to the price, the weight and the acoustic performance according to the demand objectives of the product development manufacturer.

[0074] Specifically, it is necessary to assign corresponding weights to price, weight, and acoustic performance, respectively, according to the demand objectives of the product development manufacturer. Different product development manufacturers have different requirements for the performance, price, and weight of acoustic materials. Some product development manufacturers pay more attention to performance, some product development manufacturers pay more attention to weight, and some product development manufacturers pay more attention to price. Therefore, there will be different emphases when calculating the performance parameter ratio. Therefore, the embodiment of the present application can determine the emphasis by assigning weight values. In other embodiments, the above weights can also be set values ​​configured according to development test data, which are not specifically limited.

[0075] S32B: Obtain the product of the price and the price weight value to obtain the target price, obtain the product of the weight and the weight weight value to obtain the target weight, and obtain the product of the acoustic performance and the performance weight value to obtain the target acoustic performance;

[0076] S33B: Obtain the sum of the conversion constant and the target weight, and calculate the logarithm of the ratio of the target price to the sum to obtain a second logarithm;

[0077] S34B: Determine the performance parameter according to the second logarithm and the target acoustic performance.

[0078] Specifically, the performance parameter can be determined by the following formula:

[0079]

[0080] Among them, q represents the performance parameter, p represents the performance comparison empirical coefficient, log10(Q1*y / (k+Q2*z)) represents the second logarithm, y represents the price, z represents the weight, k represents the conversion parameter, SAIL represents the acoustic performance, and Q1, Q2 and Q3 represent the weight values ​​of the price, weight and acoustic performance respectively.

[0081] It should be noted that the specific weight values ​​of Q1, Q2 and Q3 can be customized by the manufacturer, and the specific values ​​are not limited.

[0082] It should be noted that p represents the performance comparison empirical coefficient, which is an empirical coefficient. For example, p can be 20, which is not limited to a specific value. At this time, the performance parameter can be transformed into:

[0083]

[0084] Similarly, the above calculation formula is only one form of calculation, and a reciprocal conversion may be used instead of calculating a ratio, and a constant representing the performance parameter may also be obtained, without specific limitation.

[0085] In this embodiment, corresponding weights are assigned to price, weight and acoustic performance respectively; the target price is obtained by multiplying the price with the price weight value, the target weight is obtained by multiplying the weight with the weight weight value, and the target acoustic performance is obtained by multiplying the acoustic performance with the performance weight value; the sum of the conversion constant and the target weight is obtained, and the logarithm of the ratio of the target price to the sum is calculated to obtain a second logarithm; the performance parameters are determined based on the second logarithm and the target acoustic performance, so that different weights can be assigned to price, performance and weight according to the different requirements of different manufacturers, so as to find a development balance point that is more suitable for product development manufacturers, so as to better adapt to the requirements of different product development manufacturers and define more matching performance parameter indicators for each product development manufacturer, which is more targeted.

[0086] It can be seen that in the embodiments of the present application, for the calculation of the comprehensive performance of acoustic materials, in a specific application scenario, the product development manufacturer can calculate the most comprehensive performance evaluation value based on the actual situation, without specific limitation.

[0087] like Figure 3 As shown, Figure 3 , which is a schematic diagram comparing the performance parameters and sound insulation of 8 kinds of acoustic materials calculated based on the material data in Table 1, wherein the abscissa represents the acoustic material, and each group of acoustic materials includes wherein the long bar represents the acoustic performance (sound insulation), and the short bar represents the performance parameter calculated by the embodiment of the present application, Figure 3 It can be clearly seen that the best sound insulation performance (i.e. Figure 3 The acoustic material 5) in the embodiment is not necessarily the most cost-effective, but the acoustic material 5 is the most suitable. Therefore, product development generally aims to obtain the best sound insulation performance at the lowest cost and weight. Therefore, it is more meaningful and more practical to use the performance parameters determined in the embodiment of the present application to evaluate the comprehensive performance of the acoustic material.
