摘　　要：为提升铰接移动式起重机的刚度和轻便性,提出铰接移动式起重机的立柱和动臂系统结构优化新框架,并根据建立的铰接移动式起重机立柱和动臂系统新模型对起重机进行材料配置,对最大应力和挠度值进行评估,以确保符合规范要求。将优化后的立柱和动臂系统与优化前的立柱和动臂系统进行了对比分析,结果表明,与系统结构优化之前相比,尽管在优化模型中去除了大量的材料,从而使得系统质量减少了30 kg,但立柱和动臂系统的刚性并没有因为使用材料减少而变弱,优化后的立柱和动臂系统的最大应力和最大挠度值相对于优化前有了明显减小。To improve the stiffness and portability of an articulated mobile crane,a structural optimization framework of the column and boom system of an articulated mobile cranes is proposed.In addition,according to the new model of the articulated mobile crane column and boom system,the material configuration of the crane is carried out,and the stress and deflection values are evaluated to ensure that the specifications are met.The optimized column and boom system is compared with that before optimization.Comparison results show that compared with system structure before optimization,although in the optimization model for a large number of materials,so as to make the system quality decreased by 30 kg,but the pillar and movable arm system rigidity does not become weak because of the material of the save.On the contrary,the maximum stress and maximum deflection of the optimized column and boom system are obviously reduced compared with those before optimization.
