【摘要】 随着社会现代化进程不断深入,各类物资的流动速度日益加快,流动规模日益扩大,对物流自动化装备的需求也更加迫切。作为物流运输的重要一环,物流输送装备的发展决定着整个物流系统的速度和效率。因此,研究物流输送装备发展现状,进而设计更为顺畅和快捷的物流输送系统,显得尤为必要。自适应摩擦驱动技术,是一种创新型物流输送方式。首先,相对于带式输送、板式输送、辊式输送、悬挂输送等传统物流输送方式,自适应摩擦驱动输送具有高效、柔性、节能、环保低噪声等特点。其次,自适应摩擦驱动技术克服了普通摩擦驱动技术的不足。通过设计柔性摆式摩擦驱动单元,使摩擦驱动技术从单维摩擦驱动转化为多维摩擦驱动,既可实现直线输送,还可方便实现转弯、上下坡等柔性驱动。首先,本课题分析了物流输送装备的发展现状,对自适应摩擦驱动输送的优势进行了分析,论证了课题研究的必要性;接下来,建立Ⅰ～Ⅳ型摩擦驱动系统静力学模型,对其进行静力学与运动学特性分析,并根据分析结果,设计新Ⅴ型摩擦驱动系统,进而对其进行静力学与运动学特性分析;然后,根据Ⅰ～Ⅴ型摩擦驱动系统的运动特性分析结果,对自适应摩擦驱动系统的关键影响因素进行了分析研究,并开发了系统设计指导软件。最后,对本论文的研究工作和所取得的研究成果进行了总结,并结合研究过程中的体会,提出了进一步的展望。更多还原

【Abstract】 With the deepening of social modernization, flow rate of material is accelerating, and flow scale of material is growing, so the requirements of logistics automation equipment become much more urgent. As an important part of logistics and transport, the development of logistics and transportation equipment determines the speed and efficiency of logistics system. Therefore, it’s particularly necessary that studying the current status of logistics transportation equipment development and designing a more smooth and efficient transport logistics system.Adaptive friction drive technology is an innovative way to transport logistics. First, relative to traditional delivery method of transport logistics (such as belt conveyor, slat conveyor, roller conveyor, suspension conveyor and so on), adaptive friction drive transmission has the features of efficiency, flexibility, energy-saving, environmental protection and low noise. Second, adaptive friction drive technology overcomes the lack of general friction drive technology. Through designing flexible tilting friction drive unit, one-dimensiona friction drive turns into multi-dimensional. It can not only achieve line-transmission, but also facilitate the achievement of turning, on the downhill and other flexible drive ways.First, this subject analysised the development of logistics transportation equipments, and found the advantages of adaptive friction drive transmission, and then, demonstrated the need to research it. Next, static models ofⅠ~Ⅳfriction drive systems were set up, and the static and kinematic analysis of these types was finished. Then, according the analysis result, I designed a newⅤ-type friction drive system, and finished its static and kinematic analysis. Next, according the analysis result ofⅠ~Ⅴtypes, key factors of adaptive friction drive system were analyzed, and a guide software for system design was developed.Finally, this paper’s studies and results were summarized, and, combined with the experience during the research, further prospects was made.更多还原
