摘要
混凝土泵车是一种高效的建筑机械设备,常应用于各种复杂的现场工作,臂架系统作为混凝土输送装置的重要组成部件,在工程施工中扮演着关键角色.文中通过对混凝土泵车臂架的研究,提出了一种混凝土泵车臂架的拓扑优化方案.以某新型混凝土泵车 6 节臂架为研究对象,利用ADAMS对泵车臂架的三维模型进行刚柔耦合分析,研究臂架结构的展开过程中的每节臂架节点应力随角度变化的关系,得到每节臂架的应力最大处的角度,将此角度作为优化的角度,将此时销轴孔力作为边界条件并展开优化.以强度刚度作为响应约束条件,以质量最小为目标优化得到一种材料最优分布的优化方法,并为臂架系统的设计和拓扑优化提供理论指导.
Abstract
As an efficient construction machinery and equipment,concrete pump truck is often used in various complex field work.As an important component of concrete conveying device,boom system plays a key role in engineering construction.In this paper,on the basis of the study of boom of concrete pump truck,a topology optimization proposal of concrete pump truck boom is put forward.Taking six booms of a new concrete pump truck as the research object,the rigid-flexible coupling analysis of the three-dimensional model of the boom of the pump truck was carried out by ADAMS,and the relationship between the node stress of each boom and the angle during the development of the boom structure was studied,and the angle of the maximum stress of each boom was obtained,which is taken as the optimization angle,and the pin hole force is taken as the boundary condition and optimized.Taking the strength and stiffness as the response constraint condition and the minimum mass as the optimization objective,an optimization method for the optimal distribution of materials was obtained,which provides theoretical guidance for the design and topology optimization of boom system.
