Design of Heavy Rotating Stage of Chimeric Telescopic Glass Trestle Based on Topology Optimization Algorithm

现代舞台设计和优化主要集中于设备优选及机构设计,忽略了大型舞台装备材料结构性能的优化。结构性能的优化对降低材料成本、减少在役期间能耗、提高产品性能具有重要作用。此研究首先完成目标旋转舞台的机构及框架设计,然后利用双向渐进结构优化算法对旋转舞台的旋转部和伸缩部进行以满足承重条件的结构拓扑优化设计,最后对优化前后的方案进行仿真实验对比。结果表明,在满足承重性能条件下目标对象收敛于较优的形态,所应用的拓扑优化算法自动生成结构合理、有机的形态,达到了轻量化设计目的,对舞台设备在服役期节能减排和提高产品整体效能具有一定的参考价值。

The modern stage design and optimization mainly focus on equipment optimization and mechanism design,ignoring the optimization of structural performance of the large-scale stage equipment materials.The optimization of structural properties plays an important role in reducing material costs,reducing energy consumption during in-service periods,and improving the product property.In this study,the mechanism and frame design of the target rotating stage are first completed;then the bi-direction evolutionary structural optimization(BESO)algorithm is used to optimize the structural topology of the rotating part and the telescopic part of the rotating stage to meet the load-bearing conditions.The results show that the target object converges to an optimal shape under the condition of satisfying the load-bearing performance,and the applied topology optimization algorithm automatically generates a lightweight design with reasonable structure and organic shape.Therefore,it has a certain reference value for energy saving and emission reduction of stage equipment during the service period and improving the overall efficiency of the product.
