Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0038] Example 1

[0039] Figure 1 This is a flowchart illustrating an intake pipe structure adjustment method according to Embodiment 1 of the present invention. This embodiment is applicable to situations where the intake pipe structure is adjusted according to the noise reduction target. The method can be executed by an intake pipe structure adjustment device, which can be implemented in hardware and / or software and can be configured in a computer. Figure 1As shown, the method includes:

[0040] S110. Obtain the first intake pipe digital model corresponding to the intake pipe structure.

[0041] The intake manifold refers to the vehicle engine's air intake system. It delivers air with high dryness and cleanliness to the engine, effectively preventing the entry of air containing impurities and large dust particles into the combustion chamber, thus reducing abnormal wear during engine operation. Noise reduction is a crucial function of the intake manifold. Since intake noise has a significant impact, and the intake manifold affects engine power, noise quality, and passenger comfort, a rational noise reduction design for the vehicle's intake manifold is essential. This efficient control of noise fundamentally maximizes the vehicle's noise, vibration, and harshness (NVH) performance, better leveraging the diverse functions of the intake system and improving vehicle operating efficiency. The first intake manifold digital model refers to a digital model generated through simulation of the intake manifold structure.

[0042] Optionally, obtaining a first intake pipe digital model corresponding to the intake pipe structure includes: determining an air entity within the intake pipe structure, wherein the air entity is an air structure corresponding to the intake pipe structure; simulating the air entity to create a first intake pipe digital model, wherein the first intake management digital model includes an intake pipe cavity.

[0043] Specifically, the controller can determine the air entity within the intake duct structure. The air entity refers to the shape of the air flowing through the intake duct, i.e., the air structure corresponding to the intake duct structure. After extracting the air entity from the intake duct structure, NVH can perform simulation based on the air entity to create the first intake duct digital model. Figure 2 This embodiment provides a schematic diagram of the intake manifold digital model. The intake manifold digital model is a parameter-adjustable and drivable digital model, mainly including a muffler housing and a muffler core. The muffler core has four partitions, dividing the core into five sections, or five cavities, as shown below. Figure 2 As shown, AE represent the five chambers of the intake manifold.

[0044] S120. Determine the first noise loss calculation result based on the first intake pipe digital model, and adjust the first intake pipe digital model based on the first noise loss calculation result to generate the second intake pipe digital model.

[0045] Specifically, the noise loss calculation result refers to the noise transmission loss, which is a quantification of how much noise energy the sound insulation material can block, i.e., the noise blocking capability of the air intake pipe. Figure 3 This embodiment provides a schematic diagram of noise loss calculation results. Figure 3In the diagram, the horizontal axis represents frequency, and the vertical axis represents transmission loss. Figure 3 It includes five noise reduction amplitudes, each corresponding to an intake pipe cavity. The center frequency corresponding to cavity A is 1160Hz, cavity B is 1480Hz, cavity C is 1940Hz, cavity D is 2650Hz, and cavity E is 840Hz.

[0046] Furthermore, the controller can determine the intake pipe structure that meets the noise reduction requirements by adjusting the intake pipe digital model and updating the structural layer parameters in the digital model. That is, the first noise loss calculation result can be determined based on the first intake pipe digital model. At the same time, the controller will determine whether the first noise loss calculation result meets the noise reduction requirements of the intake pipe. If it meets the noise reduction requirements, the structure of the first intake pipe digital model can be directly locked. If it does not meet the noise reduction requirements, the first intake pipe digital model can be adjusted based on the first noise loss calculation result, that is, the structural parameters in the first intake pipe digital model can be adjusted to determine the second intake pipe digital model and ensure that the second intake pipe digital model meets the noise reduction requirements of the intake pipe. This can significantly save data modification and interaction time.

[0047] S130. The intake pipe structure is adjusted using the second intake pipe digital model so that the adjusted intake pipe structure meets the noise reduction requirements of the intake pipe.

[0048] Specifically, since the second intake pipe digital model is designed to meet the noise reduction requirements of the intake pipe, the controller can adjust the intake pipe structure according to the specific structure of the second intake pipe digital model. This allows the intake pipe structure to meet the needs of different center frequencies within different intake pipe cavities, making acoustic design more convenient. The noise reduction requirements for the intake pipe can be set by the user as needed. The user refers to the person performing the intake pipe noise calculation. For example, the noise reduction requirement could be a noise reduction amplitude of 20dB. When the noise reduction amplitude of each intake pipe cavity reaches 20dB, the intake pipe meets the noise reduction requirements.

[0049] The technical solution of this invention calculates the first noise loss by obtaining the first intake pipe digital model corresponding to the intake pipe structure, adjusts the first intake pipe digital model to generate a second intake pipe digital model that meets the noise reduction requirements of the intake pipe, and finally uses the second intake pipe digital model to adjust the intake pipe structure. This eliminates the need for repeated manual structural design and accurately determines the structure that meets the requirements, thus improving development efficiency.

[0050] Example 2

[0051] Figure 4This is a flowchart of an intake pipe structure adjustment method provided in Embodiment 2 of the present invention. This embodiment adds a process to Embodiment 1 above, where a first noise loss calculation result is determined based on a first intake pipe digital model, and the first intake pipe digital model is adjusted based on the first noise loss calculation result to generate a second intake pipe digital model. The specific content of steps S210 and S250 is largely the same as steps S110 and S130 in Embodiment 1, and therefore will not be repeated in this embodiment. Figure 4 As shown, the method includes:

[0052] S210. Obtain the first intake pipe digital model corresponding to the intake pipe structure.

[0053] Optionally, obtaining a first intake pipe digital model corresponding to the intake pipe structure includes: determining an air entity within the intake pipe structure, wherein the air entity is an air structure corresponding to the intake pipe structure; simulating the air entity to create a first intake pipe digital model, wherein the first intake management digital model includes an intake pipe cavity.

[0054] S220. Determine the first noise loss calculation result based on the first intake pipe digital model.

[0055] Optionally, the calculation result of the first noise loss is determined based on the first intake pipe digital model, including: determining the first structural parameters corresponding to the first intake pipe digital model; and determining the calculation result of the first noise loss based on the first structural parameters.

[0056] Among them, structural parameters refer to parameters related to the internal structure of the intake pipe, including the spacing between the intake pipe cavity baffles, the diameter of the perforations, the distance between the perforations and the baffles, the number of perforations, the axial spacing of the perforations, the radial spacing of the perforations, and the angle between the two sets of perforations. Figure 5 A schematic diagram of the internal structure of the intake pipe is provided for an embodiment of the present invention. Figure 5 In this diagram, spacing 1 to spacing 5 refers to the spacing between the baffles in each intake pipe cavity, diameter 1 to diameter 5 refers to the perforation diameter in each intake pipe cavity, axial hole spacing 1 refers to the axial hole spacing corresponding to cavity A, hole-to-baffle distance 1 refers to the distance between the perforation corresponding to cavity A and the baffle, two sets of hole angles 1 refers to the angle between the two sets of perforations corresponding to cavity A, and radial hole spacing 1 refers to the radial spacing of the perforations corresponding to cavity A. Based on the structural parameters of the first intake pipe digital model, the air entity flowing through the intake pipe can be determined, and thus the first noise loss calculation result can be determined.

[0057] S230. When it is determined that the first noise loss calculation result does not meet the noise reduction requirements of the intake pipe, the target cavity in the first intake pipe digital model is determined according to the first noise loss calculation result.

[0058] Optionally, the target cavity in the first intake pipe digital model is determined based on the first noise loss calculation result, including: determining the noise reduction amplitude corresponding to each intake pipe cavity in the first noise loss calculation result; and taking the intake pipe cavity with a noise reduction amplitude less than a preset threshold as the target cavity.

[0059] Specifically, if the first noise loss calculation result does not meet the noise reduction requirements of the intake pipe, it means that the noise reduction amplitude of the intake pipe cavity in the first noise loss calculation result does not reach the preset threshold. At this time, it is necessary to adjust the structure of the intake pipe cavity that does not reach the preset threshold. Therefore, the controller will determine the target cavity in the first intake pipe digital model according to the first noise loss calculation result. The target cavity refers to the cavity that needs to be structurally adjusted. The controller can determine the noise reduction amplitude corresponding to each intake pipe cavity in the first noise loss calculation result. When the noise reduction amplitude does not reach the preset threshold, it indicates that the noise reduction effect of the cavity is not ideal. For example, the preset threshold can be 20dB. At this time, the controller will take the intake pipe cavity with a noise reduction amplitude of less than 20dB as the target cavity.

[0060] S240. Adjust the target cavity to generate a digital model of the second intake pipe.

[0061] Figure 6 This invention provides a flowchart of an intake pipe structure adjustment method according to Embodiment 2. Step S240 mainly includes the following steps S241 to S242:

[0062] S241. Obtain the adjustment instructions input by the user, wherein the adjustment instructions include the partition spacing adjustment parameters, radius and offset constraint parameters, perforation adjustment parameters and angle adjustment parameters.

[0063] Specifically, users can input adjustment commands through a user terminal connected to the controller to adjust the structure of the intake manifold digital model. User terminals include, but are not limited to, mobile terminal devices such as mobile phones, laptops, digital radio receivers, PDAs (Personal Digital Assistants), PADs (Tablet PCs), and PMPs (Portable Multimedia Players). The controller can display the determined target cavity to the user through the user terminal, allowing the user to input adjustment commands to adjust the target cavity. These commands include parameters for adjusting the baffle spacing, radius and offset constraints, perforation adjustment, and angle adjustment. The baffle spacing adjustment parameter is a translation command, allowing for translational adjustment of the baffle spacing within the target cavity. The radius and offset constraint parameters allow for adjustment of the diameter of the circumferential perforations in the target cavity and the distance between the perforations and the baffles. The perforation adjustment parameters allow for adjustment of the number of perforations, the axial spacing of the perforations, and the radial spacing of the perforations within the target cavity. The angle adjustment parameter is a rotation command, allowing for adjustment of the angles of two sets of perforations. The user-input adjustment commands can include one or more of these parameters.

[0064] S242. Adjust the target cavity according to the adjustment command to generate the adjusted intake pipe digital model, and determine the second intake pipe digital model according to the adjusted intake pipe digital model.

[0065] Optionally, the second intake pipe digital model is determined based on the adjusted intake pipe digital model, including: determining the second structural parameters corresponding to the adjusted intake pipe digital model, generating a second noise loss calculation result based on the second structural parameters; when the second noise loss calculation result meets the noise reduction requirements of the intake pipe, the adjusted intake pipe digital model is used as the second intake pipe digital model.

[0066] Specifically, the purpose of the user input adjustment command to adjust the intake pipe digital model is to make the intake pipe digital model meet the noise reduction requirements of the intake pipe. Therefore, the controller can adjust the target cavity according to the adjustment command to generate the adjusted intake pipe digital model. The controller will determine the second structural parameters corresponding to the adjusted intake pipe digital model. The second structural parameters include the spacing between the intake pipe cavity partitions, the diameter of the perforation, the distance between the perforation and the partition, the number of perforations, the axial spacing of the perforations, the radial spacing of the perforations, and the angle of the two sets of perforations. The second structural parameters can be used to determine the air entity flowing through the intake pipe, and then the second noise loss calculation result can be determined. When the second noise loss calculation result meets the noise reduction requirements of the intake pipe, that is, when the noise reduction amplitude corresponding to all intake pipe cavities is greater than the preset threshold, the adjusted intake pipe digital model will be used as the second intake pipe digital model. Otherwise, the user will continue to adjust the intake pipe digital model until the noise reduction requirements of the intake pipe are met, and the second intake pipe digital model is determined. Each intake pipe cavity in the second intake pipe digital model meets the user's noise reduction requirements.

[0067] S250 uses a second intake pipe digital model to adjust the intake pipe structure so that the adjusted intake pipe structure meets the noise reduction requirements of the intake pipe.

[0068] The technical solution of this invention calculates the first noise loss result by obtaining the first intake pipe digital model corresponding to the intake pipe structure. The first intake pipe digital model can be adjusted by the adjustment command input by the user, and the noise loss is calculated on the adjusted digital model to generate a second intake pipe digital model that meets the noise reduction requirements of the intake pipe. Finally, the intake pipe structure is adjusted using the second intake pipe digital model. The structure that meets the requirements can be accurately determined without repeated manual structural design, thus improving development efficiency.

[0074] Optionally, the second intake pipe digital model generation unit specifically includes: a target cavity determination subunit, used to determine the noise reduction amplitude corresponding to each intake pipe cavity in the first noise loss calculation result; and to take the intake pipe cavity with a noise reduction amplitude less than a preset threshold as the target cavity.

This eliminates the need for repeated manual structural design and accurately determines the structure that meets the requirements, thus improving development efficiency.
