基于LabVIEW的视觉检测系统软件框架设计

机器视觉检测系统通过采集目标图像,并对获取的图像进行处理、分析,从而获取目标的信息并产生相应的执行动作。针对典型视觉检测系统包含的相机(工作平台)运动控制、图像采集、图像处理以及执行机构动作控制等基本功能的实现,描述了一种在LabVIEW环境下实现上述功能的视觉检测系统软件框架设计。     

巴贡水电站面板堆石坝填筑的加载次序及其影响

本文通过对马来西亚巴贡水电站面板堆石坝,实际填筑施工过程的描述,找出了在实际施工中约束大坝全断面、均匀铺筑碾压上升的各种限制因素,并阐述了针对这些因素,在巴贡面板堆石坝填筑中,实际所采取的坝体加载次序,且以巴贡工程的实测观测数据为基础,对实际所采取的坝体加载方式对坝体变形的影响作了一些初步分析,分析结论对高面板堆石坝的填筑施工具有一定的参考价值。

马来西亚巴贡电站堆石坝施工石料调配的规划方法

实现堆石坝施工最佳的土石挖填平衡的经济目的,很大程度决定于动态的、同时点的挖填强度之适配性。调配挖填强度在同时点的适配性,是决定堆石坝施工挖填规划经济性的最关键问题。结合巴贡工程的实践,介绍了一种针对此问题的优化求解方法。     

Compound forming technology of outside 3D integral fin of copper tubes

Using rolling-ploughing-extrusion compound processing methods, a 3D integral-fin structure on outside surface of red copper tube with diameter of 16.0 mm and wall thickness of 1.5 mm was obtained. When both rolling depth and ploughing-extrusion (P-E) depth were 0.2 mm, rotating speed was 50 r/min, feed speed was 0.16 mm/r, 3D fin structures with height of 0.25 mm were gotten. Two different fin structures were obtained in grooves formed with rolling-ploughing-extrusion compound forming technology and observed by scanning electron microscope(SEM). One is the compound structure with V-shaped groove and U-shaped groove, and the other is the single structure with V-shaped grooves. Two kinds of groove structures obtained by rolling processing and ploughing extrusion processing are restricted together by groove interval and rolling depth, and pitch and P-E depth, respectively. Based on the analysis of interaction of rolling and P-E processing, it is found from the result that the outside 3D integral-fin can be achieved by rolling-ploughing-extrusion compound processing when single V-shaped groove structures are formed by both rolling and P-E processing.
