摘要
本文针对普遍有“减重量、保性能”需求的直升机工艺装备,提出基于拓扑优化、结构仿真的数字化工艺装备结构设计流程,通过多种工况集成作用下的拓扑优化实现减重结构设计。优化分析时综合考虑多工况条件提取及权重分配、制造工艺性、美观性、人机功效性等因素,获得工艺装备最佳承力结构,将刚度、频率等结构仿真技术融于拓扑优化过程,随概念设计、详细设计完成工艺装备的性能评估,进一步发挥仿真技术预判、加快设计进度的优势。以某型号直升机钻孔类工艺装备为例,应用拓扑优化及仿真验证技术,结合增材制造工艺,实现钻模非参数化减重结构设计制造,对比传统类似钻模,重量减轻接近50%、设计周期缩短40%,取放及安装等操作可由单人完成,人机功效水平显著提高。
In this paper,aiming at the helicopter process equipment with the general demand of“reducing weight and ensuring performance”,a digital process equipment structure design process based on topology optimization and structural simulation is proposed,and the weight reduction structure design is realized through topology optimization under the integration of various working conditions.In the optimization analysis,factors such as multi-working condition extraction and weight distribution,manufacturing manufacturability,aesthetics,man-machine efficiency and so on are comprehensively considered to obtain the best load-bearing structure of process equipment.Structural simulation technologies such as stiffness and frequency are integrated into the topology optimization process,and the performance evaluation of process equipment is completed with conceptual design and detailed design,so as to further give play to the advantages of simulation technology in predicting and speeding up the design progress.Taking the drilling process equipment of a certain helicopter as an example,the design and manufacture of the non-parametric weight-reducing structure of the drilling jig is realized by applying topology optimization and simulation verification technology,combined with additive manufacturing technology.Compared with the traditional similar drilling jig,the weight is reduced by nearly 50%,the design cycle is shortened by 40%,the operations such as picking,placing and installation can be completed by a single person,and the human-machine efficiency level is significantly improved.
