Non-pneumatic tire numerical simulation analysis and verification method

Abstract

This invention belongs to the field of numerical simulation technology for non-pneumatic tires, and specifically provides a numerical simulation analysis and verification method for non-pneumatic tires. It includes the following steps: S1: Establishing a geometric model and detection points; S2: Non-pneumatic tire rotation method; S3: Numerical simulation analysis and verification of the non-pneumatic tire; S3.4: Analysis and verification of sound field simulation results. This invention employs a composite rotational simulation method combining MRF and SM, fully leveraging the dual advantages of rapid initial flow field acquisition through steady-state calculations and accurate capture of dynamic characteristics through transient calculations. The simulation analysis and verification method of this invention has been successfully applied to subsequent biomimetic noise reduction research on non-pneumatic tires. On the verified simulation platform, parametric design and orthogonal experimental optimization were performed using the serrated leading edge structure of an owl's wing feathers, ultimately achieving a noise reduction effect of 3.64 dB, fully demonstrating its engineering application value.
