【摘要】：随着社会的进步与经济的发展,越来越多的人出现了亚健康的状态,比如肥胖、高血压、颈椎问题等,经研究骑马运动能够很好的缓解这些症状,但是室外骑马健身对大多数人来说不够现实,故而需要一款能够仿生马匹慢跑的室内运动器械,健身骑马机应运而生。本文中,健身马的机构设计是上届师兄健身马项目的延续。首先,通过查阅相关资料,在深入了解马的运动规律、机构组合以及机构变异理论的基础上,采用对曲柄摇杆机构和圆柱凸轮机构组合进行合理拟合的方法,实现了对马慢步行走时“V8”型运动规律的模拟。其中,由曲柄摇杆机构变异得到的偏心轴机构模拟马的纵向“8”字形运动,圆柱凸轮机构模拟马的横向摆动。然后,利用Pro/e软件初步设计各零部件的三维模型,并在装配后进行了必要的动力学仿真和稳定性分析,而后根据所需提供的扭矩来选取了合适的直流电动机。接着,初步设计出控制系统的第一套方案并加以实施。该系统以AT89C52单片机为核心,并选取合适的PWM直流调速器以及信号隔离器来降低控制系统的误差。该方案能够实现对健身马运行速度的调节,但是却不能显示有负载时电机的实际运转速度。因此,本文又进一步推出了改进版控制电路方案,增加了测速模块,将LED显示模块更换为LCD显示模块,并利用Proteus与Keil C联调进行了电路仿真,达到了预期的效果。在整个控制程序的设计中,均采用C语言,在Keil C软件中进行编辑完成。最后为了丰富健身马的娱乐功能,增添了MP3功能的设计,使健身者在健身的同时也能享受到音乐带来的快乐。最后为了使健身马的功能多样化,进行了基于富士通MB9BF506芯片的嵌入式系统的探索。
[Abstract]:With the development of society and economy, more and more people appeared in the sub-health state, such as obesity, hypertension, cervical problems, the study of horse sports can well alleviate the symptoms, but the outdoor riding fitness for most people is not realistic, and therefore need a indoor sports equipment bionic horse jogging the fitness riding machine came into being.
In this paper, the mechanism design is a continuation of the previous senior fitness horse horse fitness project. First of all, through access to relevant information, in-depth understanding of the movement of the horse, and the foundation of mechanism combination mechanism variation theory, using the method of reasonable fitting combination of crank rocker mechanism and cam mechanism, the horse slowly walk when the "V8" type motion simulation. The longitudinal "8" motion simulation of eccentric shaft horse mechanism obtained by variation of the crank rocker mechanism, horizontal swing simulation horse cylinder cam mechanism. Then, the three-dimensional model of parts preliminary design using Pro/ E software, and the dynamic simulation and stability analysis is necessary in the assembly, and then according to the required torque to select suitable DC motor.
Then, the first set of preliminary design of the control system is implemented. The system uses AT89C52 microcontroller as the core, and select the appropriate PWM DC converter and signal isolator to reduce the error of the control system. The scheme can realize the adjustment of the fitness horse running speed, but can not show the actual motor speed when loading therefore, this paper further introduced an improved version control circuit, increased speed module, LED display module to replace the LCD display module, and use Proteus and Keil C debugging of circuit simulation, to achieve the desired effect. In the design of the control program, using C language to edit in the Keil C software.
Finally, in order to enrich the entertainment function of the fitness horse, add the design of MP3 function, so that the fitness people can enjoy the happiness brought by the music while they are at the same time. Finally, in order to make the function of the fitness horse diversified, we have explored the embedded system based on Fujitsu MB9BF506 chip.
