摘要

摘要: 提出双吊点塔式起重机起重臂正向设计方法,进行塔机的高效轻量化设计。在用力法求解拉杆内力进而计算控制截面最大应力的基础上,将起重臂弦杆的等强度作为约束条件建立了起重臂臂架结构的数学模型,用遗传算法进行第一次设计优化得到臂架结构和等截面弦杆的基本参数。进一步用ANSYS系统的APDL建立参数化有限元模型,第二次优化得到起重臂臂架的变截面结构参数。对某型号塔机进行正向设计,并将设计结果与该型号塔机现有设计结果分析对比,表明正向设计方法合理、轻量化效果明显。

Abstract: A top-down design method of the tower crane boom with double lifting points was proposed to improve the design efficiency and achieve its lightweight. Constant strength of hoist boom's chord was set as constraint condition, and mathematical models of its jib structure were built based on solving maximum stress of the control section after solving rod's internal force with the force method. Rational geometry shape of jib structure and prismatic sectional dimension of chord were obtained by genetic algorithm optimization, then parameterized finite element model was built with APDL in ANSYS program to optimize variable section structure. Finally, a type of tower was designed forward and the design result was compared with existing tower, which shows that the top-down design method is reasonable, and the effect of lightweight is obvious.
