摘要: The present application relates to a sound absorber unit and a vehicle wheel having a sound absorber comprising at least one sound absorber unit or at least one sound absorber module which is composed of a plurality of sound absorber units as a whole. The sound absorber unit is constructed into a box body in a hexahedron shape, a three-layer Helmholtz resonance sound absorption structure with double holes and single holes combined is formed, and meanwhile, the sound absorber unit or the sound absorber assembly forms a structural resonance sound absorber. According to the application, the double-absorption wheel air chamber sound resonance function organically combining Helmholtz resonance sound absorption and structural resonance sound absorption can be realized.

摘要: The invention relates to the field of aluminum wheel casting molds, and more particularly relates to a closed-loop control method and system for a mold temperature in a wheel casting process. The control method includes: step 1, acquiring data, that is, acquiring a plurality of mold position temperatures, and cooling pipeline opening and closing signals in a target wheel casting process according to a fixed frequency; step 2, storing, based on acquired mold opening and closing signals of casting equipment, the acquired data in a database in the form of a unique ID according to a single wheel casting process; step 3, calculating new process parameters based on the acquired plurality of position temperatures and time; and step 4, integrating the calculated process parameters, and issuing the process parameters to a PLC of a casting equipment to perform new casting. According to the invention, the temperature control parameters are calculated based on the acquired temperature data and time process to form the temperature control process of the casting process, which solves the technical problem of significant fluctuations in the quality of the low-pressure casting process of aluminum wheels and improves casting stability and yield.
