【摘要】：根据地铁自动检票机的票卡回收模块整体功能要求,分析了模块机械系统和控制系统的整体架构,并给出了机械结构组成和控制系统的性能指标,以此为基础分别对模块机械结构和控制系统进行了详细设计与分析研究。在设计机械结构时,设计了模块整体结构布局,然后完成了模块传送机构、票卡升降机构和储票箱的结构设计,采用了多从动轮传动的双皮带传送机构,提出了满足储票箱工作要求的同步带升降机构,并选择了符合换向器机构动作要求的电磁铁型号；在ABAQUS/Explicit软件模块中建立了两种换向器机构下票卡与换向器接触碰撞有限元模型,对票卡接触碰撞瞬间进行了仿真分析,得到票卡的应力应变图及其卡芯的应力曲线,确保票卡及其芯片不受损害；在进行控制系统设计时,给出了模块控制系统整体结构,设计完成了模块整个控制系统的硬件电路,并介绍了系统软件的整体框架及其工作流程。本文着重对模块机械结构和控制系统进行了设计与研究,加工出了产品的机械结构,而所做的控制系统方面的工作为产品后续生产提供了参考。
[Abstract]:According to the whole function requirement of ticket card recovery module of automatic ticket checking machine, the whole structure of the mechanical system and control system of the module is analyzed, and the composition of the mechanical structure and the performance index of the control system are given. On this basis, the mechanical structure and control system of the module are designed and analyzed in detail. When the mechanical structure is designed, the overall structural layout of the module is designed, and then the structural design of the module transfer mechanism, ticket card lifting mechanism and ticket storage box is completed. The synchronous belt lifting mechanism which meets the working requirements of the storage box is put forward, and the electromagnet model which meets the operational requirements of commutator mechanism is selected, and the finite element model of contact collision between the ticket card and commutator of two commutator mechanisms is established in Abaqus / explicit software module. The stress and strain diagram of ticket card and the stress curve of card core are obtained by simulation analysis of ticket card contact impact moment, so as to ensure that the card and its chip are not damaged. In the design of control system, the whole structure of module control system is given. The hardware circuit of the whole control system of the module is designed and the whole frame of the system software and its work flow are introduced. This paper focuses on the design and research of the module mechanical structure and control system, and processes the mechanical structure of the product, and the work of the control system provides a reference for the follow-up production of the product.
