液压万能材料试验机的测控系统操作原理

发布时间:2019-12-9 8:44:22  浏览:

材料试验机是一种常用的力学试验设备,用于测试各种材料的力学性能。随着各行业对新材料的需求越来越广泛,材料的力学性能测试已成为关键。传统试验机只能靠试验人员观察,根据经验加以手工调整,通过指针表盘的读数计算得到材料性能数据,操作复杂。按照现行的材料测试标准,传统拉力试验机无法达到要求,也将逐渐被淘汰。因此,本研究将基于Delphi语言的软件技术与基于单片机的自动控制技术相结合,应用于万能材料试验机的控制系统中,通过对通用材料拉伸、压缩等试验标准进行分析的基础上,建立万能试验机测控系统软硬件与试验标准规程之间的关系,提出模块化的上、下位机软件及硬件的设计方法。机电工程第29卷本研究在建立测控系统上位机软件及下位机软、硬件平台的基础上对所提出的模块化实验设计方法进行评价,同时进行多目标持荷试验、水泥胶砂抗压试验以及金属拉伸试验,以期解决万能材料试验机皇冠即时比分功能单一、试验扩展复杂的缺点。
