  • Publication number: 20250005231
    Abstract: A method and system for inversion of tire material parameters for wheel performance simulation. Based on a plurality of sets of test data obtained through tire radial rigidity and lateral rigidity tests, a tire radial rigidity and lateral rigidity test finite element simulation model is established, and error calculation is performed by comparing simulation results; and then the tire material parameters are optimized by optimizing a platform and combining results of error analysis, and a simulation process is circulated until the error is minimal, which is fitting of a test curve and a simulation curve. By using a neural network model, rapid inversion of the tire material parameters may be realized by using the neural network model only through non-destructive tire rigidity test data. The tire material parameters may be modified according to a large deformation process of a tire in a 90-degree impact test of a wheel.

  • Publication number: 20240323120
    Abstract: Embodiments of the present disclosure provide a packet matching method and apparatus, a storage medium, and an electronic device. The method includes: determining multiple Hash calculation results corresponding to a key value of a packet; indexing addresses in multiple counter groups respectively according to the multiple Hash calculation results, so as to determine multiple counters, wherein one counter is indexed in one counter group; determining one target counter from the multiple counters; acquiring a target entry at a corresponding position of an off-chip memory according to the address of the target counter; in a case where the target entry is equal to the key value, determining that the packet matches the target entry.

  • Patent number: 12005733
    Abstract: A sound absorber unit and a vehicle wheel having a sound absorber device are provided. The sound absorber devices includes at least one sound absorber unit or at least one sound absorber assembly which is composed of a plurality of sound absorber units. The sound absorber unit is constructed into a box body in a hexahedron shape and forms a three-layer Helmholtz resonance sound absorption structure with double holes and single holes combined, and meanwhile, the sound absorber unit or the sound absorber assembly forms a structural resonance sound absorber. The double-absorption wheel air chamber sound resonance function organically combining Helmholtz resonance sound absorption and structural resonance sound absorption can be realized.
