温度-应力试验机的温度控制系统设计(任务书,开题报告,外文翻译,论文13000字)
摘要
水泥混凝土一直以来都是建筑工程施工中重要的材料之一，其应用领域遍及世界，从公路到桥梁，从港口到机场，从平房到高楼，都离不开水泥混凝土。然而水泥混凝土的使用过程中也出现了诸多的问题，其中最大的问题就在于混凝土的开裂问题，一个完整的混凝土结构，如果不发生开裂，那么整个混凝土结构就是十分稳固的，但是如果由于温度等原因，致使混凝土结构内部出现了裂缝，那么就会出现连锁反应，导致整个混凝土结构变得十分不稳定，就可能造成人力财力物力损失，甚至会造成人员伤亡，所以研究水泥混凝土的开裂性是十分重要的。
本文是对温度应力实验机的温度控制系统进行研究，通过查阅国内外温度应力试验机的发展状况以及研究现状，使用温度应力试验机对水泥混凝土抗裂性能的研究，研究温度变化对混凝土结构抗裂性能的影响，从而得到最新的结论。本文采用理论与实际相结合的方法，对温度应力实验机的温度控制系统进行研究。
本文第一章主要介绍了温度应力试验机研究背景以及国内外研究的现状，第二章到第四章着重介绍了温度应力试验机的温度控制系统的设计方案，方案分为硬件方案和软件方案，硬件方案主要是对实验装置的设计以及温度采集设备、温度控制设备进行选型等，另外硬件部分包括传感器的设置、信号调理电路的设计的、数据采集系统的设计以及温升温降系统的设计。软件部分则使用虚拟仪器技术，通过虚拟仪器技术来实现对于温度应力试验机的温度控制系统的软件设计，本次采用的软件是美国NI公司的LabVIEW 2014版，利用此软件设计出数据采集程序、数据保存程序、温度控制程序以及系统前面板，其中数据采集程序还使用了数据库技术，通过数据库将温度历史数据进行储存，然后显示到显示模块之中。 [版权所有：http://DOC163.com]

Abstract
Cement concrete has always been one of the most important materials in the construction of construction projects. Its application covers the world. From the highway to the bridge, from the port to the airport, and from the bungalow to the high-rise, cement concrete is indispensable. However, there are many problems in the use of cement concrete. The biggest problem lies in the cracking of concrete, a complete concrete structure. If no cracking occurs, then the entire concrete structure is very stable, but if it is due to temperature, etc. As a result, cracks appear inside the concrete structure, then there will be a chain reaction, resulting in the entire concrete structure becomes very unstable, it may cause loss of human and financial resources and material, and even cause casualties, so the study of the cracking of cement concrete is very important.
This article is to study the temperature control system of the temperature stress testing machine. Through consulting the development status and research status of the domestic and foreign temperature stress testing machines, the temperature stress testing machine is used to study the crack resistance of the cement concrete, and the temperature change resistance to the concrete structure is studied. The impact of cracking performance, resulting in the latest conclusions. In this paper, the temperature control system of the temperature stress testing machine is studied by the combination of theory and practice. [来源：http://www.doc163.com]
The first chapter of this paper mainly introduces the research background of the temperature stress testing machine and the status quo of domestic and international research. The second chapter to the fourth chapter focus on the design of the temperature control system of the temperature stress testing machine. The scheme is divided into hardware and software solutions. The hardware solution mainly includes the design of experimental devices and the selection of temperature acquisition equipment and temperature control equipment. In addition, the hardware includes the setting of sensors, the design of signal conditioning circuits, the design of data acquisition systems, and the design of temperature rise and temperature drop systems. . The software part uses the virtual instrument technology to realize the software design of the temperature control system for the temperature stress testing machine through the virtual instrument technology. The software used this time is the LabVIEW 2014 version of the NI company in the United States. The data acquisition program is designed using this software. The data storage program, temperature control program, and system front panel, in which the data acquisition program also uses a database technology to store temperature history data through the database and display it in the display module.
