颚式破碎机机架的有限元分析及拓扑优化

Finite Element Analysis and Topology Optimization of the Frame of Jaw Crusher

基于鄂式破碎机机架重量较大,结构不合理的现状,运用有限元分析软件hyperworks建立颚式破碎机机架的有限元模型;根据颚式破碎机的力学分析对其进行有限元静强度分析;根据有限元分析结果,以颚式破碎机机架的重量最小为目标,颚式破碎机机架的最大应力为约束条件,对其进行拓扑优化设计,得出颚式破碎机机架更加合理的模型,对后续颚式破碎机机架的减重优化和对企业生产有一定的指导意义。

Based on the large weight of the frame of the jaw crusher, the structure is not reasonable. Firstly, the finite element model of the jaw crusher frame was established by hypermesh, and then the finite element analysis was carried out according to the mechanical analysis of the jaw crusher. With a jaw type crushing machine frame of the minimum weight as the goal, jaw broken machine frame of the maximum stress as constraint conditions, the topology optimization design, draw the jaw crusher machine more reasonable model, on subsequent jaw type crushing machine weight optimization of the and of the production enterprises have certain guiding significance.
