摘要
为了降低压缩机原料成本,采用Inspire软件对某型号涡旋压缩机机架进行拓扑优化设计,并将原模型和优化模型对比,质量减轻约1 kg。优化后机架抱紧力与原模型基本一致,止推面间隙差异约为1.9μm,轴承最大变形量为4.9μm,不会影响装配和运转;止推面接触压强分布与优化前没有明显差异。
In order to reduce the cost of raw materials used for compressors, the Inspire software is adopted for topology optimization of the scroll compressor housing, and the original model is compared with the optimized model. As a result, the weight has reduced about 1 kg. The optimized housing’s holding force is basically the same as that of the original model, the difference of the thrust surface clearance is about 1.9 μm, and the maximum change of bearing deformation is 4.9 μm, which does not affect assembly and operation. The contact pressure distribution of the thrust surface is not significantly different from that before optimization.
