摘　　要：针对高炉送风装置中补偿器内部捣打料振动成型作业工况进行分析,采用三维建模软件及有限元分析软件对振动夹具进行设计及仿真,确定在提升振动夹具结构稳定性及固有频率为指标对夹具进行结构优化。研究结果表明:经设计优化后夹具较初始夹具一阶固有频率提升约109%,整体质量较中期状态夹具减重约9%(约70 kg),夹具经谐响应分析共振峰值在625 Hz远高于夹具工作频率40~90 Hz,在其工作频率60 Hz时变形量为2.3×10^(-3)mm。研究成果为该型振动补偿器捣打料振动成型技术解决了技术工装问题,为同类型夹具设计提供了参考依据。Based on the analysis of the vibration molding operation condition of the compensator in blast furnace,the vibration fixture is designed and simulated by using 3D modeling software and finite element analysis software,and the structural optimization of the fixture is determined to improve the structural stability and natural frequency of the vibration fixture.The results show that after design optimization,the first order natural frequency of the fixture is increased by about 109%compared with the initial fixture,and the overall mass is reduced by about 70 kg by about 9%compared with the fixture in the middle stage.The resonance peak value of the fixture in harmonic response analysis is 625 Hz,which is much higher than the working frequency of the fixture 40~90 Hz,and the deformation is 2.3μm when the working frequency is 60 Hz.The research results can solve the technical tooling problem for the vibration molding technology of this type vibration compensator,and provide a reference for the design of the same type fixture.
