Mechanism Design and Movement Simulation of Table Tennis Serving Machine Based on Single-chip
ABST源自文库ACT
Under the circumstance that Chinese table tennis players have been constantly making outstanding achievements, more people are enjoying table tennis and preferring to improve playing skill by training with serving machine.This thesis aims to describe the design of Single-chip-based table tennis serving machine by addressing on the characteristics of serving and requirements both on skills training and human mechanics and combining with the present market of table-tennis serving machine, and to help trainees mastering table tennis techniques better for achieving the goal of body building. The thesis is to summarize the present development both in home and foreign markets and to analyze the mechanical structures of the existing serving machines. Moreover, the designing philosophies and procedure, operating principles and structural features of table tennis serving machine, which include the selecting principles for external facilities, motors and the PWM Drivers, will also be described in detail to prove the stability of the operating system.The reasonable parameter spans，which are for controlling the dropping points，are confirmed by establishing mathematical model to describe the mechanical analysis on the fling process of the ball. At the same time, MATLAB is used for motion simulation.The designed table tennis serving machine is consisted by two parts: mechanical hardware (which is consisted by 11 parts: the equipment to store balls, poking ball institutions, helical ball Sending institutions, Height adjusting mechanism, Yaw rate institutions, swings institutions, serving machine, base frame, Limit reinforcement stents, simple and easy removable hand rods and transmission mechanism) and controlling system. The serving machine is driven by servo motors which can serve balls in all Rotating directions.This equipment takes AT89C51 monolithic integrated circuit as the control core, which is designed to be a new-model，cost-effective and simply equipped serve machine. It can be controlled by the push-button controls for the serves with dynamic spins and various levels of speed. To conclude, this table tennis serving machine is convenient which can satisfy the different user's training needs.

基于单片机的乒乓球发球机构设计及运动仿真
摘要
随着我国乒乓球运动员不断在世界各级比赛中取得优异成绩，喜爱乒乓球运动和打乒乓球的人越来越多，同时，利用乒乓球发球机来提高乒乓球技术水平的人也越来越多。为了使练习者能更好地学习乒乓球技术以达到健身和训练的目的，本文针对已有乒乓球发球的特点、技能训练需求、人体力学的需求，再结合现有乒乓球发球机的市场需求，设计了一种新型、简易的乒乓球发球机：基于单片机的乒乓球发球机。本文综述了国内外乒乓球发球机的现状，对已有发球机的机械结构进行分析，对乒乓球发球机的设计思想、工作原理、结构特点及控制系统进行了详细论述，详细介绍了该控制系统的设计过程，具体包括外围设备的选择、电动机的选择、PWM驱动器的选择等，论证说明了该控制系统的可靠性。根据乒乓球飞行过程的受力分析建立了数学模型，并利用MATLAB进行运动仿真，分析出控制落球点各参数的合理取值范围，得出其相互制约关系。设计的乒乓球发球机包括机械结构部分（主要由储球机构、拨球机构、螺旋送球机构、高度调整机构、横摆机构、纵摆机构、发球机构、机座、限位加固支架、简易可拆卸手拉杆以及传动机构等十一部分组成）以及控制系统部分，由伺服电动机驱动，可发出多种带有不同旋转性质的球。采用AT89C51单片机作为控制的核心，是一种新型、性价比高的简易自动型乒乓球发球机，使其可以通过按键来控制实现供球的快慢，发球的力度、旋转、球速。使用方便，可满足不同的用户训练需求。
