Kinetic Energy Compensation of Tire Absence in Numerical Modeling of Wheel Impact Testing 2005-01-1825
Impact characteristics of aluminum wheels are evaluated in accordance to the testing procedure SAE J175. In an effort to simplify the numerical modeling of wheel impact testing, numerical analysis has been conducted to investigate the percentage of the striker kinetic energy absorbed by the tire during the impact test. 10%, 15%, 20%, 25%, and 30% reductions of the striker kinetic energy were computed in order to assess the appropriate percentage reduction. Comparisons of wheel plastic deformations of both experimental and numerical methods illustrate that a 20% reduction in the striker kinetic energy provides an effective approach to simplify the modeling.
