本文对ZL30装载机动臂在对称载荷综合工况条件下采用光弹性实验进行应力分析,确定了该工况条件下的边界应力分布曲线及应力值,并与电测结果进行了比较。对ZL30装载机的动臂结构以等强度的观点提出评价。
In this paper, the stress analysis of ZL30 loader boom under the condition of symmetrical load is carried out by using the photoelastic experiment. The boundary stress distribution curve and stress value under this working condition are determined and compared with the measured results. The boom structure of the ZL30 loader was evaluated with equal strength.
