支撑托架是下行式移动模架造桥机的核心部件，通过建立支撑托架的有限元分析模型，利用Ansys有限元计算方法，对900 t造桥机支撑托架进行了振型分析，分析结果表明其自振频率密集，支撑托架结构的动力性能复杂。通过对支撑托架的稳态响应分析，确定支撑托架在承受随时间按正弦规律变化荷载时的稳态响应，可为支撑托架的进一步优化提供理论依据。
支撐託架是下行式移動模架造橋機的覈心部件，通過建立支撐託架的有限元分析模型，利用Ansys有限元計算方法，對900 t造橋機支撐託架進行瞭振型分析，分析結果錶明其自振頻率密集，支撐託架結構的動力性能複雜。通過對支撐託架的穩態響應分析，確定支撐託架在承受隨時間按正絃規律變化荷載時的穩態響應，可為支撐託架的進一步優化提供理論依據。

The support bracket is the core of the downward moving bridge fabrication machine .For the support bracket of the 900t bridge fabrication machine , the paper builds the finite element analysis model and adopts the Ansys finite ele-ment calculation method to analyze the vibration mode of the support bracket .Analyses show that the self-vibration frequen-cy is high and the dynamic performance of the support bracket is complicated .Through the steady-state response analysis on the support bracket , the steady state response of the support bracket bearing the load with time changing as sine wave is de -termined, which can provide theoretic basis for further optimization of the support bracket .
