将箕斗斗箱壁视为折板受有变化载荷的弯曲问题,建立了有限元计算模型,并在10:1模型箕斗上进行了实验,对斗箱壁的静、动态应变进行了实测。比较程序计算结果与实测值可知:部分吻合较好,部分相差较大。作者分析了误差原因并指出用传统的筒仓理论计算箕斗箱壁载荷时,应给予适当修正。 The bucket hopper wall is regarded as the bending problem that the bent plate is subjected to varying loads. The finite element calculation model is established and the static and dynamic strain of the bucket wall is measured on the 10: 1 model skip. . Comparing the calculated results with the measured values ​​shows that the partial agreement is good and the difference is quite large. The author analyzed the cause of the error and pointed out that the traditional silo theory should be applied to correct the load on the bucket wall.
