Modal Analysis of Automobile Wheels based on Lightweight Technology

Compared with traditional wheels, magnesium alloy wheels have the advantages of higher strength, toughness, lighter weight, beautiful appearance and so on. This paper takes magnesium alloy wheel as the research object, and uses Pro/e and ANSYS to help complete a lot of work such as 3D model construction and finite element analysis and calculation, to ensure that the magnesium alloy wheel can meet its strength requirements while being lightweight. The strength analysis and modal analysis of the designed wheel model are carried out under various working conditions. According to the analysis results, the first design model is further simplified, and then the calculation and analysis are repeated many times. It is found that the new model meets the mechanical properties requirements under multi-working conditions, ensures that the requirements of lightweight design are met, and provides relevant theories and methods for wheel design and structural optimization of other materials.
