Virtual bench model for aluminum alloy rim impact test

The invention discloses a virtual bench model for an aluminum alloy rim impact test. The virtual bench model comprises an impact test bench finite element model and a rim finite element model, wherein the impact test bench finite element model comprises a steel plate beam, a mounting disc and bases, the bottom plate is provided with two rubber supports, the steel plate beam is obliquely arranged, the two ends of the bottom of the steel plate beam are hinged to the two bases respectively, the two bases are connected with the two rubber supports respectively, and the mounting disc is mounted on the steel plate beam; the central axis of the mounting disc is perpendicular to the mounting surface of the steel plate beam; the rim finite element model is installed on an installation disc of the impact test bench finite element model. According to the invention, the number of physical tests is reduced, the die development and repair cost is reduced, the development period is shortened, and the development cost of sam
