【摘要】 为了探索改善工业平缝机动态性能的方法,引入声强谱分析、声强模式分析和运转振型模式分析。通过理论推导,开发了上述分析程序软件,并利用实验测试和计算机分析,研究了该机在空运转的振动和噪声特性,以便有效地改进该机的动态设计。更多还原

【Abstract】 In order to find ways to improve the dynamic Characteristics of Industrial Sewing Machines, Sound Intensity Spectrum, Sound Intensity Patterns and Operational Deflection Shapes are introduced into the an- alyses of dynamics in Sewing Machines.By theoretical analysis, computing softwares, which can be used widely, are set up. Meanwhile, Dynamic Characteristics (mainly noise and vibration) of Industrial sewing Machines are studied by experiment measurements and computer simulation.更多还原
