The invention relates to a hoisting carrying pole reinforcement method based on simulation modeling and a hoisting carrying pole, and the method comprises the steps: building a finite element model, which mainly comprises the structure of the hoisting carrying pole determined according to engineering design, and drawing a three-dimensional solid model of the hoisting carrying pole; endowing the three-dimensional solid model with material attributes; carrying out unit grid division on the three-dimensional solid model of the hoisting shoulder pole; applying constraint and load to obtain a finite element model, and performing simulation calculation on the established finite element model to obtain stress of each part of the hoisting shoulder pole; the three-dimensional solid model of the hoisting carrying pole is modified, reinforcing ribs are arranged at the positions where the stress of the hoisting carrying pole is larger than a threshold value, and the steps are repeated till the stress of each position of the hoisting carrying pole meets the threshold value. The method has the advantages that the stress of each part of the hoisting carrying pole is comprehensively analyzed through a scientific simulation modeling method and a finite element calculation method, so that the parts with relatively large stress are checked, and then the parts are specifically reinforced through the reinforcing ribs, so that the structural strength of the hoisting carrying pole is improved.

    本发明涉及一种基于仿真建模的吊装扁担加筋方法及吊装扁担,包括:建立有限元模型,主要有根据工程设计确定的吊装扁担的结构,绘制吊装扁担的三维实体模型;对三维实体模型赋予材料属性;将吊装扁担的三维实体模型进行单元网格划分;施加约束,施加载荷,得到有限元模型,对建立的有限元模型仿真计算,得到吊装扁担各处的应力;修改吊装扁担的三维实体模型,在吊装扁担的应力大于阈值的位置设置加强筋,重复上述步骤,直至吊装扁担各处的应力均满足阈值。其优点在于,通过科学的仿真建模方法和有限元计算方法来全面分析吊装扁担各处的应力,从而排查出应力较大的部位,而后针对这些部位通过加强筋特定补强,从而提高吊装扁担的结构强度。
