本文对复摆颚式破碎机机架,用有限元法八结点等参数单元进行强度计算,得到了机架变形和应力的变化规律。结合电测应力分析,其结果与数值解进行了比较。 In this paper, the strength of the compound pendulum jaw crusher frame is calculated by using finite element method such as eight nodes, and the variation rules of the deformation and stress of the frame are obtained. Combined with electrical stress analysis, the results were compared with the numerical solution.
