根据装载机的实际作业特点，将工作装置横梁位置在可行域内移动，对动臂分别进行了有限元分析，研究横梁位置对动臂强度、刚度的影响，从而确定横梁的最合理位置，使动臂强度、刚度最好，结构设计最为合理。
According to the actual operation characteristics of the loader, the beam position of the working device is moved in the feasible region, and the boom is analyzed by finite element method respectively. The influence of beam position on boom strength and stiffness is studied to determine the most reasonable position of beam, Arm strength, stiffness, structure design is the most reasonable.
