摘要
用有限元法对斗杆可回转挖掘机的工作装置进行了分析，并对两种约束处理方案进行了分析，建立了闭口薄壁杆件约束扭转双力矩的简化计算公式。
A working device of hydraulic excavators with rotatable bucket arm is analyzed by the finite element method. Two kinds of restricted handling methods are analyzed. Abrief torsional-double-moment formula of the thin wall rods is set up.
