用有限单元法电算对液压起重臂进行了刚度和强度计算,得出了常规计算方法难以计算的结构中各点的位移值和应力值,并分析了计算结果,为BY-13型液压起重臂的设计提供了可靠的设计依据。
The stiffness and strength of the hydraulic boom are calculated by the finite element method. The displacement and stress of each point in the structure which is difficult to calculate by conventional calculation method are obtained. The calculation results are as follows: BY-13 hydraulic pressure The boom design provides a reliable design basis.
