摘要
伸缩臂作为煤矿辅助作业装备的主要执行机构,其应用场景复杂,使用环境恶劣。为实现矿用伸缩臂结构进一步优化,须提高其可靠性及使用效果。以某型2级伸缩臂为研究背景,基于响应面法对其关键元部件进行优化分析,优化后伸缩臂满载状态下等效应力值减小约17%。现场实践表明:伸缩臂优化设计方案合理,在装备结构稳定的基础上有效地改善了整体受力状态,满足特定使用要求。
Telescopic boom is the main actuator of auxiliary equipment in coal mine,and its application scene is complex and its application environment is harsh.In order to further optimize the structure of telescopic boom in coal mine and improve its reliability and application effect,the key components of a two-stage telescopic boom are optimized and analyzed based on response surface method.After optimization,the equivalent stress value of telescopic boom under full load is reduced by about 17%.The field practice shows that the optimal design scheme of telescopic boom is reasonable,and the overall stress state is effectively improved on the basis of stable equipment structure,meeting the specific use requirements.
