《多功能跑步机的设计》-毕业论文（设计）.doc

摘 要 跑步机是家庭及健身房常备的器材，而且是当今家庭健身器材中最简单的一种，是家庭健身器的最佳选择。专家们相信未来跑步机市场将以普及和人性化为主，所以跑步机行业的研究设计和开发拥有较好前景。 本课题是首先调查和总结市场上现有的跑步机的优缺点，然后完成多功能跑步机的设计。本课题主要的功能有折叠功能，不用时可以折叠起来从而节省摆放空间；手动调节坡度功能，让用户在跑步时可以体验不同坡度跑步的感觉；自动微调功能可以根据使用者跑步速度的变化而跟着变化，实现让跑步机跟着用户跑等功能。另外本设计的多功能跑步机便于搬运、结构简介、外观美观、人性化设计。除跑步功能外，还有美腰、扭腰、仰卧起坐、背颈部震动按摩等健身方式供用户选择。 本设计先通过预估后进行强度计算进行校核，对电动机选择和传动系统经过精确的设计和计算，并作出合理的选择；然后设计出牢固、简洁又合理美观外部基架结构，并对多功能设计的结构也做了一定的设计，并画出了重要部件的CAD图。 最后完成一个较为完整、实用性强的多功能跑步机设计。 关键字：健身器材 跑步机 多功能 ABSTRACT The race apparatus is the family and apparatus always on the alert of gymnasium, and the simplest one in the body-building apparatus of the current family, it is the best choice of the family building up body device.The experts believe the race apparatus market will take high price products as the leading factor in the future.the race apparatus will still increase continuously in the future. This task is firstly find the advantage and disadvantage of the treadmill and then fulfill the design of the multifunctional treadmill. The main function of the folding design features can be folded up when not in use to save display space;Manual adjustment of slope feature allows users to run different slope can experience the feeling of running; auto-tuning function can change the speed of the user running along with changes, which allows users to run and so on treadmill followed.Also the design of multi-running machine to facilitate handling, structural profiles, exterior appearance, humanity design. In addition to running features, there are US-waist, wriggled, sit-ups, dumbbell, fitness back and neck massage vibration mode for the user to choose. This design strength calculation after the first estimate was corrected, by a lot of calculation and verification, design not only strong, beautiful and simple and reasonable structure of the internal drive and external base frame design, and multi-functional design of the structure to do a certain design. And draw an important component of CAD map. Then make out a
