摘要
针对液压支架护帮装置结构件经常出现损坏,且损坏位置大体相同等问题,从护帮结构、焊缝形式及焊接效果入手,应用Inventor建立了护帮及连杆三维模型。对于焊接装置所受的应力大小不仅与焊接工艺有关,而且还与装置的结构尺寸有关。为了减小焊接装置的工作应力,运用ANSYS Workbench工作环境,以护帮装置的结构尺寸为输入参数、最大应力为输出参数,通过优化护帮装置的结构尺寸来减小其工作时所受的最大应力。经过优化计算,得到护帮装置主要参数的优化值,优化后护帮装置所受的应力明显减小。
Contrapose the problems of hydraulic support holding streel the device often appear and damage damage in the same position, work from the holding streel structure, type of weld and welding effects, using Inventor built the 3D models of holding streel and links. The stress size in addition to the welding process other than the size of the structure of the holding streel. In order to reduce the stress of the weld, using ANSYS workbench environment, the structure and size of holding streel at the input parameters, maximum stress of the holding streel at the output parameter, from the optimization of the size of the structure of the holding streel to reduce the stress of the weld. Through optimization simulation, getting the main parameters of holding streel, stress of holding streel are obviously reduce before optimization.
