斗轮堆取料机门座架有限元分析及优化

FEM Simulation and optimization of the portal frame bucket wheel stacker reclaimer

斗轮堆取料机门座架处于机器下方,起着支撑整台机器和联接行走机构的作用,门座架的安全性与可靠性对整台机器的安全运行十分重要。若门座架的强度、刚度不足,都会对门座架及整机造成威胁。为了提高门座架的安全可靠性,文章利用有限元分析软件ANSYS建立了门座架的有限元模型,先进行静力学分析发现门座架支腿处应力值偏大,超出材料的许用应力值。针对这一情况对门座架支腿进行结构优化,优化后的支腿最大应力、应变值都减小,达到了设计要求,门座架的安全可靠性得到了保证和提高。

Bucket wheel stacker reclaimer portal frame is below the whole machine,play support and join the machine running the whole body, the door mounts on the safety and reliability of the safe operation of the whole machine is very important.If the portal frame strength, stiffness lack of door mounts and the machine will cause insecurily.In order to improve safely and reliability of door mounts, we use finite element analysis software ANSYS to establish the portal frame finite element model,first the static portal frame analysis showed thai the stress value of the leg is too large, beyond the allowable stress of the material value.In response to this door mounts legs to optimize the structure optimized outrigger maximum stress and strain values are reduced to achieve the design requirements, safety and reliability of portal frame is assured and enhanced.
