Abstract:
In this paper, the dynamic analysis of the drum and ball collision process is carried out, the optimization model is established with the height and force of the bouncing ball as the optimization objective and the dynamic equation as the constraint condition, and the best collaboration strategy of the team is discussed. Under ideal conditions, the best collaboration strategy of the team is as follows: first, the team members control the drum to be located at the same definite height, and then the ball drops 0.06 s before the drum is lifted with 44.19 N force. After that, each time the ball falls 0.004 s, all members lift the drum with a force of 40.01 N, and the drum may return to its original position after collision. In practice, the drumhead may tilt due to the uncertainty of performance intensity and when to lift. By analyzing the forces and movement trend of the tilting drum, it is found that the performance timing of the team members is a more important factor to ensure that the “concentric drum” stays level as far as possible without tilting.
