摘要:
为研究不同材质底板对球体在三维非定常流场中运动轨迹及气动性能的影响，笔者采用无网格格子Boltzmann方法对乒乓球三维非定常流场进行求解。结论如下：四种工况下的乒乓球与球拍碰撞之前轨迹相同。碰撞发生后，乒乓球轨迹在y轴方向产生较大偏差，即弹性恢复系数越大，碰撞后轨迹终点线越高，反射角越大；弹性恢复系数对球体运动过程中的运动速度和旋转速度影响较大。
Abstract:
In order to study the influence of different base plate materials on the trajectory and aerodynamic performance of the sphere in three-dimensional unsteady flow field.Numerical Solution of Three-Dimensional Unsteady Flow Field of Table Tennis Based on Meshfree Lattice Boltzmann Method for Solving ThreeDimensional Unsteady Flow Field of Table Tennis Based on Meshfree Lattice Boltzmann Method.The conclusions are as follows：Table tennis in the four conditions is the same as the trajectory before the collision with the racket.After the collision，Table tennis trajectory produces large deviations in the y-axis direction.It means that the greater the elastic recovery coefficient，the higher the track finish line and the larger the reflection angle after collision.The elastic recovery coefficient has a great influence on the movement speed and rotation speed during the movement of the sphere.
