斗轮堆取料机前臂架有限元静强度与刚度的分析

Analysis of Finite Element Static Intensity and Stiffness of the Bucket Wheel Stacker-reclaimer of Forearm Frame

斗轮堆取料机是当今世界上最大的散料处理成套设备之一,生产率高,因而越来越受到世界各国的重视。前臂架作为堆取料机的主要构件,质量大,受力情况复杂,其工作的可靠性直接决定着整机的性能。本文以DQL1200/1200.30型斗轮堆取料机的功能部件前臂架为研究对象,利用CEA分析软件ANSYS计算与分析前臂架在零工位取料工况下的受力情况,得到前臂架的应力和应变云图,其过程及结论对前臂架设计具有指导意义和参考价值。

Bucket wheel stacker reclaimeris one type of equipments which is the largest bulk material handling machinery in the world,it has been paid more and more attention all over the world because of its high productivity. Forearm frame is an imporlant part of Bucket wheel stacker-reclaimer. The self-weight of the cantilever is heavy. The forces on the cantilever of bucket wheel stacker-reclaimer are complex. The reliability of its work directly determines the performance of machine. The DQ1.Z1200/1200.30 bucket wheel stacker reclaimer forearm frame,as the research object, by making use of CEA static analysis ANSYS to calculate and analyze the loading condition of forearm frame under the chore of a material taking condi tion to get the stress strain contours of forearm frame. The process and conclusions of portal design have direct significance and reference value compared with the previous calculation.
