摘要
建立空调压缩机上法兰与壳体的三点焊接过程的有限元模型,并采用ANSYS软件进行计算.首先仿真镂空、非镂空、综合三种结构上法兰的焊接温度分布,然后根据温度结果采用间接耦合法仿真相应的焊接变形,并进行对比分析.通过与实际焊接结果相比较对所建立的模型进行检验.结果表明,镂空结构的上法兰的焊接变形最大,而非镂空结构上法兰在焊接之后的变形低于综合结构.因此,非镂空结构设计有利于降低空调压缩机的焊接变形.
The finite element model of the three-points welding processes for the condition compressor upper flange and its case was developed.The ANSYS software was applied.The temperature distributions of the three structures such as pierced,non-pierced and composite were simulated.Based on the temperature results,the relevant welding deformation were simulated by indirect coupling method.These deformations for the upper flange with different structures were compared and analyzed.The model was validated by the experimental welding results.Both the simulation and experimental results showed that the welding deformation of pierced upper flange was maximum.The deformation of the non-pierced was lower than that of the composite.Hence,the non-pierced upper flange was beneficial to decrease the welding deformation of condition compressor.
