摘要
针对传统人工上水逐渐难以适应高铁飞速发展的问题,提出一套基于视觉定位的高铁自动上水装置方案。首先,以更丰富的卷积特征(RCF)边缘检测算子为核心搭建高铁注水口外盖板视觉识别系统,依据功能需求划分各功能模块并进行相应结构设计;其次,基于ANSYS对关键部件开闭盖板机构进行静力学分析,探寻其最大应力与变形位置;最后,利用ADAMS对开闭盖板执行机构进行运动分析与振动响应分析,获得其动态特性参数。结果表明:所提出的方案具有良好的力学性能与动态特性,为提高上水效率进而实现高铁上水自动化提供了新思路。
Aiming at the problem that the traditional manual water-feeding method is gradually difficult to adapt to the rapid development of high-speed railway,a scheme of automatic waterfeeding device for high-speed railway based on visual positioning was proposed.Firstly,a visual recognition system for the outer cover plate of high-speed railway water injection port was built with the core of the richer convolutional features(RCF)edge detection operator,and each function module was divided according to the function requirements and the corresponding structures were designed.Secondly,based on ANSYS,the static analysis of the key component,the opening and closing cover plate mechanism,was carried out to find out its positions with the maximum stress and the maximum deformation.Finally,based on ADAMS,the motion analysis and vibration response analysis for the actuator of the opening and closing cover plate was carried out to obtain its dynamic characteristic parameters.The results show that the proposed scheme has good mechanical properties and dynamic characteristics,which provides a new idea for improving the water-feeding efficiency and realizing the water-feeding automation of high-speed railway.
