Finite element analogue simulation evaluation method and system for tire sidewall depression

Abstract

The invention provides a finite element analogue simulation evaluation method and system for a tire sidewall depression, and relates to the technical field of tire simulation design. Comprising the following steps: establishing a two-dimensional pneumatic tire simulation model to simulate a tire inflation and assembly process to obtain a two-dimensional axial symmetry section of the tire; based on the two-dimensional axial symmetry section of the tire, establishing a three-dimensional static pneumatic tire simulation model containing a tire body joint to simulate a tire inflation process; obtaining the transverse expansion displacement of the tire side area part in the tire inflation state; calculating and comparing carcass joint area depression values of different design schemes, and screening to obtain the design scheme generating the minimum sidewall depression value; a physical tire is produced by adopting a design scheme with a minimum sidewall depression value, and visual and touch tests are carried out. According to the method, the design scheme generating the small maximum depression value is screened out, whether the tire sidewall depression occurs or not is tested and determined, the experimental test time cost and material cost for producing a real tire can be reduced, the development period is shortened, and the development cost is reduced.
