2100BL挖掘机斗杆有限元强度分析

Stress analysis on the dipper handle of the 2100BL mining shovel based on FEM

应用SuperSAP程序对2100BL型挖掘斗杆进行了强度分析，得出不同工况下的最大应力值及危险截面位置该结果与P＆H公司发布的维修公告一致，为进一步改进结构设计提供了依据。

The authors utilize Super SAP to calculate the strength of the model P&H 21O0BL＇s dipper handle and gives its maximum equivalent stresses in different working condttons. The results show no differences between the dangrous sections and the practical bamage sections. It provides the basis for further improving the structure design of 2100BL mining shovel,s dipper handle.
