公路大件货物运输支座选取研究

在公路大件货物运输过程中, 当货物作用于液压平板车架上某一点的集中载荷过大时, 易使车板发生较大的弯曲变形。针对这一问题, 需要合理确定支座数量以及最优支座位置。本文把大件货物划分为卧式容器以及非卧式容器的常规货物, 根据三水平三因素正交模拟实验方法确定卧式容器运输所需的支座数量, 通过容器的应变分析结果以及支座反力的求解结果进行最终的优化布置; 对非卧式容器常规货物支座数量的选择以及摆放位置, 则按照车辆不同的摆动轴数进行合理的支座选取。本文以运输卧式容器费托合成反应器为例, 结合两种确定方法, 计算分析出其运输所需的支座数量以及支座位置。该研究为实际的公路大件货物运输支座的选取提供了支持。

The Selection Study on the Bearings for Highway Oversize Cargo Transportation

During the highway oversize cargo transportation, it is easy to make the plate bending deformationwhen the concentrated load on hydraulic flat frame applying to a point is too large. In order to solve this problem, it is necessary to determine the reasonable number and optimum position of bearings. In this paper, the oversize cargos are classified as horizontal containers and non-horizontal containers.According to the orthogonal simulation method of three levels and three factors, the number of bearings needed for horizontal container transportation was determined, and the final optimal arrangement was carried out through the result of strain analysis of the vessel and the solution of the support reaction force.The number of bearingsand their placement for non-conventional goodswere determined by the number of vehicle swing axles. In this paper, the transportation of Fischer Tropsch synthesis reactor was selected as an example, and the two methods were combined to calculate and analyze the number and position for the bearings. This study provides a reasonable theoretical basis for the selection of bearings on highway oversize cargo transportation.
