[0002] With the continuous growth of global car ownership and the increasing demand of consumers for car safety performance, the automotive industry is undergoing profound changes. Lightweight, intelligent and safe have become important directions for the development of automobiles.

[0003] Under slippery road conditions, the drainage performance of traditional wheels is limited, which easily leads to the aggravation of the water film effect between the tire and the ground, which in turn causes safety problems such as tire slippage and extended braking distance. According to statistics, the traffic accident rate under slippery road conditions is much higher than that under dry roads, which poses a serious threat to people's lives and property safety. Therefore, a wetland safety and efficiency-enhancing drainage method and system for aluminum alloy wheels is proposed. Summary of the invention

[0010] In some embodiments, in S1, the radial and axial distributions of the drainage grooves are designed based on the principles of fluid dynamics and in combination with the dynamic characteristics of the tire during rotation.

[0011] In some embodiments, bionic scales or micro grooves are provided on the tire, and the bionic scales or micro grooves are precisely arranged around the drainage grooves to increase the microscopic contact area between the tire and the slippery road surface, so as to improve adhesion.

[0012] In some embodiments, in S2, three-dimensional modeling software is used to establish an accurate geometric model of the wheel hub and tire, and the drainage groove is finely meshed to improve the simulation accuracy. Complex boundary conditions are set according to factors such as vehicle speed, road wetness and tire pressure. Then, CFD software is used to simulate and analyze the flow field around the wheel hub, observe the water flow path, velocity distribution and water film formation, and iteratively optimize the drainage groove design based on the analysis results.

[0013] In some embodiments, in S2, the drainage system is combined with the vehicle's braking system model to construct a complete vehicle dynamics simulation platform for simulating the braking process of the vehicle on a slippery road surface. The road surface module in the simulation software is used to set road conditions of different degrees of slipperiness.

The drainage system is performance tested and verified on the bench test system. By adjusting the test parameters, the actual performance of the drainage system is observed and recorded, and the test results are compared and analyzed with the simulation results to evaluate the accuracy and reliability of the simulation model.

[0023] An embodiment of the present invention provides a wetland safety and efficiency-enhancing drainage method for an aluminum alloy wheel hub, comprising the following steps:

[0024] S1. Drainage structure design: Based on demand and market research results, and using fluid dynamics principles for simulation, optimize the design parameters of the drainage trough to improve drainage efficiency and wetland grip;

[0025] S2. Simulation: Use CAD software to build a three-dimensional model of the drainage system, integrate it with the aluminum alloy wheel body, and use CAE software for simulation analysis to simulate the water flow path, drainage speed, and tire-ground contact force parameters under slippery road conditions to verify the rationality of the design.

[0026] S3. Simulation experiment verification: Build a test platform in a laboratory environment and conduct experimental verification on the simulation results to ensure their accuracy and reliability.

[0027] In this embodiment, specifically, in S1, based on the simulation analysis of fluid dynamics, the performance of V-shaped, U-shaped and trapezoidal troughs under water flow velocity and pressure is evaluated in detail, and by comparing the drainage efficiency, water flow velocity distribution and water film residue of the V-shaped, U-shaped and trapezoidal troughs, the optimal trough type is selected as the V-shaped trough, and the trough depth is further adjusted to ensure the best drainage effect while minimizing material consumption.

[0028] In this embodiment, specifically, advanced FEA software is used to perform structural analysis of the wheel hub under multiple working conditions, including extreme working conditions such as high-speed driving, sudden braking, and turning. During the analysis, the focus will be on the impact of the drainage system on the overall stiffness, strength, and dynamic stability of the wheel hub. Based on the analysis results, local reinforcement design is performed on key stress-bearing parts of the wheel hub, which may include adding reinforcing ribs, optimizing the cross-sectional shape, and using higher-strength aluminum alloy materials. At the same time, ensure that the reinforcement design does not affect the performance and aesthetics of the drainage system.

[0029] In this embodiment, specifically, in S1, according to the principles of fluid dynamics and combined with the dynamic characteristics of the tire during rotation, the radial and axial distribution of the drainage grooves are designed to ensure that during the rotation of the tire, the water flow can be quickly discharged along the preset path to reduce water film retention. At the same time, considering the changes in the contact area between the tire and the ground, the distribution density of the grooves is optimized to improve the overall drainage performance.

[0030] In this embodiment, specifically, bionic scales or tiny grooves are provided on the tire, and the bionic scales or tiny grooves are precisely arranged around the drainage grooves to increase the microscopic contact area between the tire and the slippery road surface, so as to improve adhesion.

[0031] In this embodiment, specifically, in S2, a precise geometric model of the wheel hub and the tire is established using 3D modeling software, the drainage groove is finely meshed to improve the simulation accuracy, and complex boundary conditions are set according to factors such as vehicle speed, road wetness, and tire pressure. By adjusting these conditions, water flow behaviors under different working conditions are simulated.

[0032] Then, CFD software is used to simulate and analyze the flow field around the hub, observe the water flow path, velocity distribution and water film formation, and iteratively optimize the drainage groove design based on the analysis results.

[0033] In this embodiment, specifically, in S2, the drainage system is combined with the vehicle's braking system model to construct a complete vehicle dynamics simulation platform for simulating the braking process of the vehicle on a slippery road surface. The road surface module in the simulation software is used to set road conditions of different degrees of slipperiness.

At the same time, advanced technologies such as vacuum casting or low-pressure casting are used to further improve the density and mechanical properties of aluminum alloy wheels.

[0040] Post-processing and inspection: After casting, the wheel hub is heat treated to eliminate internal stress and improve the mechanical properties and stability of the material, followed by strict appearance inspection and dimensional measurement to ensure that the wheel hub meets the design requirements.

Anodizing, electrophoretic coating and other processes can be used to form a corrosion-resistant and wear-resistant protective layer on the wheel hub surface to extend its service life.

[0044] Quality inspection and control: Establish a strict quality inspection and control system to monitor and inspect every link in the production process.
