摘要
针对涡旋压缩机机架提出了基于CAE驱动的参数化优化设计方法,并运用该方法设计了一款轻量化的机架结构。该方法通过Creo进行三维参数化自动建模,应用Optislang软件对不同尺寸进行试验设计以及对控制尺寸进行相关性和敏感性分析,再由Ansys Workbench进行结构仿真分析,分析了机架力学变化特性,最后基于DOE(试验设计)分析结果利用响应面模型进行多目标优化设计。试验结果表明,本方法可行性高,机架优化后,涡旋压缩机机架减重16%,与传统非参数化结构优化设计方法相比时间成本节省64%。
A parametric optimization method of housing of scroll compressor is proposed in this paper.In this method,three-dimensional model is established through Creo,Optislang is used for experimental design of different dimensions,correlation analysis and sensitivity analysis,then structural simulation is carried out to analyze the mechanical characteristics by Ansys Workbench.Finally,multi-objective optimization based on the DOE(Design of experiment)analysis results through response surface method is carried out.The experimental results show that this method is highly feasible,after optimization,the weight of scroll compressor is decreased by 16%,the time cost of is 64%less than time of traditional non-parametric structure optimization design.
