基于有限元法的脱水压榨机强度校核

Strength Check of Dewatering Presser Based on FEA

为了保证隧道洗衣机有良好的脱水性,根据相关规范,设计了符合隧道式洗衣机的脱水压榨机,综合运用实体单元和连接单元,建立了包括上下横梁、中间四根拉杆的有限元模型,并利用ABAQUS软件对于模型进行网格划分,施加材料属性以及必要的约束和静力载荷,最后进行了应力分析强度校核。结果表明在额定工况下,从应力云图以及位移云图验证了脱水压榨机主要部件应力均在安全范围内,其强度均满足要求。

In order to make sure for good dewatering of tunnel washer,according to related design rule,a pressing system was designed.With combination of separate unit and connected blocks,FEM model was established,including up and down beam and 4 pieces of middle bar.Adopting the software of ABAQUS,the model was divided in the way of gridding,and material characteristics and basic load was applied,and then stress intensity was proofread.The result indicates that,under the rated working condition,the stress of the main parts of the presser is within the safe scope,and intensity can meet the requirement.
