湘潭大学兴湘学院PAGE PAGE 11电磁铁推拉力测试系统——控制部分摘要：电磁铁在我们的日常生活中到处可见，应用非常广泛，生活中我们越来越离不开它。电磁铁是一种电器，它被广泛应用于机床、起重机等大型机电设备中。电磁铁的静态力性能直接影响到由它所构成的元件及装置的整体性能，进行电磁铁的静态力特性分析，对电磁铁的设计制造和实际应用具有一定的参考价值。本论文基于PLC控制步进电机和滚珠丝杆组成的机构，应用力传感器技术，对电磁铁进行推拉力测试，得到其推或拉力与衔铁位移之间的关系曲线。对西门子S7-200 PLC系统和步进电机进行深入学习，掌握了西门子S7-200 PLC系统的组成、基本指令及其功能指令。理解的步进电机的工作原理及其驱动控制技术，实现了PLC对步进电机的控制。关键词：电磁铁，S7-200，步进电机，驱动器Solenoid Push Pull Test System - Control PartAbstact：Electromagnet in our daily life everywhere, is widely used in daily life more and we can not do without it. Is an electrical solenoid, which is widely used in machine tools, cranes and other large electrical and mechanical equipment. Electromagnet static forces directly affects the performance of its composition from the overall performance of components and equipment to carry out the static force analysis of the electromagnet, the electromagnet of the design and manufacture and application has some reference value. This paper, based on PLC control of stepping motor and ball screw institution, application of force sensor technology, push pull solenoid for test, get the push or pull the relationship between the keeper and the displacement curve. Siemens S7-200 PLC system and the stepper motor in-depth study and master the Siemens S7-200 PLC system components, basic commands and features instruction. Understand the working principle of stepper motor and drive control technology, the PLC on the stepper motor control.Key words：Electromagnet, S7-200, stepping motor, drive目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc263924066 第一章 引言 PAGEREF _Toc263924066 \h 1 HYPERLINK \l _Toc263924067 1.1 电磁铁概述 PAGEREF _Toc263924067 \h 1 HYPERLINK \l _Toc263924068 1.2 课题背景及意义 PAGEREF _Toc263924068 \h 1 HYPERLINK \l _Toc263924069 1.3 国内外基本研究情况 PAGEREF _Toc263924069 \h 1 HYPERLINK \l _Toc263924070 1.4 课题的主要研究内容 PAGEREF _Toc263924070 \h 1 HYPERLINK \l _Toc263924071 第二章 理论知识介绍 PAGEREF _Toc263924071 \h 3 HYPERLINK \l _Toc263924072 2.1 PLC简介 PAGEREF _Toc263924072 \h 3 HYPERLINK \l
