悬链斗卸船机带式输送机机架的优化设计

摘要

The belt conveyer frame below the front end hanger of the hanging-chain bucket ship unloader is subject to complex stress conditions. The frame moves with the front edge hanger and vibrates under the impact of regular blanking. Through analysis and calculation for the frame, the paper puts forward 4 optimal design solutions and selects an optimal so-lution in Ansys to effectively reduce the stress concentration and maximum displacement without largely increasing the mass of the frame in operation.%悬链斗卸船机前吊架下方的带式输送机机架受力复杂,机架不仅随着前吊架一起运动,还会在周期性落料的冲击下发生振动,文中对机架进行了分析计算,提出了4种优化设计方案,通过Ansys对比分析,得出了一组最优解,在质量不大幅增加的前提下能有效降低机架工作时的应力集中和最大位移.
