摘　　要：|为解决现有大功率推耙机工作装置中推耙铲刀座开焊断裂问题,基于虚拟样机技术,对推耙机工况进行划分,研究导致铲刀座开焊的关键工况及相应工况下的载荷、应力分布情况,分析导致推耙铲刀座开焊的原因,并由此对推耙铲刀座结构进行优化设计。分析结果表明,优化后推耙铲刀座结构焊缝的受力得到改善,应力水平大大降低,能够满足实际工况使用要求。Blade mounting of a push rake has to be optimal designed to find a solution to the welding cracks at the attachment mounting of high power push rakes,which is based on technology in simulated machines, on classification of the rake's working conditions,plus studies on the load and its distribution as key factors of the rake mounting, now in failure welding. Following analyses of the welding after optimization shows improved stress bearing capability,which decreases by far the stress level there, that can satisfy requirements of the actual working conditions.
