【摘要】：AGV小车作为工业自动化的一个标志,在各个领域起着非常重要的作用。与各生产工序的柔性连接,减少成本投入的同时提高了工作效率。本课题主要依托于某公司为某电网集团建设自动化生产线,根据电网集团的实际的工作需求,本文对于AGV小车的运行工作原理进行了分析,确定了AGV小车的需求特性,根据需求特性设计开发了一种新型驱动单元的AGV小车,同时对于AGV小车的结构特性及关键技术进行了深入研究。课题初期,针对项目需求,对于国内AGV生产厂家进行了调研和考察,对于AGV相关关键技术进行了分析论述。根据电网集团自动化生产线的实际要求,提出了AGV小车所应具有的性能特性。针对特定的运行环境设计出了AGV小车的总体结构布局方案,主要包括AGV小车整车结构设计、驱动单元与车体柔性连接机构和电机布局。针对起伏有较大误差的地形提出了一种独立悬挂的新型AGV驱动单元结构,该结构在减震的同时与车体完全柔性连接,在一定程度上解决了驱动力不足,摆动打滑问题,且能够在起伏路面进行全地形工作。根据实际尺寸运用三维软件SolidWorks建立了AGV小车整体模型,为了保证小车的结构可靠性,在三维模型通过样机审核后运用ANSYS中的静力学模块对小车进行了静力学仿真,确保了结构和部件的强度寿命要求。在加工完成后针对实体小车进行了不同路况实地测试,针对测试结果提出问题及解决方案。在改进方案实施后进行了同样测试,得到了进入不同半径弯道前AGV小车应满足的速度范围,为RFID站点信息设置提供了直接依据。
[Abstract]:As a symbol of industrial automation, AGV car plays a very important role in various fields. This topic mainly relies on a company to build an automated production line for a power grid group, according to the actual work needs of the grid group. In this paper, the operating principle of the AGV trolley is analyzed, and the demand characteristics of the AGV trolley are determined. According to the demand characteristics, a new type of AGV trolley with driving unit is designed and developed. At the same time, the structure characteristics and key technology of AGV trolley are deeply studied. At the beginning of the project, the domestic AGV manufacturers are investigated and investigated. The key technologies related to AGV are analyzed and discussed. According to the actual requirements of automatic production line of power grid group. The performance characteristics of AGV trolley are put forward, and the overall structure layout scheme of AGV trolley is designed according to the specific running environment, including the whole AGV vehicle structure design. The flexible connection mechanism and motor layout between the driving unit and the car body. A new type of AGV driving unit structure with independent suspension is proposed for the terrain with large errors in the undulation. At the same time, the structure is fully connected with the car body, which solves the problem of insufficient driving force and swing skid to some extent. In order to ensure the reliability of the vehicle structure, the whole model of the AGV car is established by using the three-dimensional software SolidWorks according to the actual size. After the 3D model is verified by the prototype, the statics module of ANSYS is used to simulate the statics of the trolley. The strength life requirements of the structure and components are ensured. After processing, the physical vehicle is tested in different road conditions. According to the test results put forward problems and solutions. After the implementation of the improved scheme the same test was carried out and the speed range of AGV car should be satisfied before entering into different radius bends. Provides the direct basis for the RFID site information setting.
