Analysis of effects of rebounds and aerodynamics for trajectory of table tennis ball

Abstract

In this paper, we firstly analyze the effects of the rebounds and aerodynamics for trajectory of a table tennis ball. We firstly analyze the effect of the aerodynamics with a criterion of evaluation, where the half area of the table is considered as 9 divided areas. Furthermore, the drag and lift coefficients are identified by assuming that the rotational velocity is invalid during the ball flying. With the identified coefficients, the modeling errors of the table and racket are secondly verified by the criterion mentioned previously. Some conclusions are finally shown.
