摘要
针对我国高速铁路在施工建设过程中架设桥梁的需求,对900 t级架桥机的提梁小车的U型凹式结构进行常规计算与有限元分析,分析激励频率对支撑结构的影响,为机构选型和修正运动参数提供参考。
In view of the demand of building bridges in the construction process of high-speed railway,the paper applies routine calculations and finite element analysis to U-shaped concave structure of the winch trolley of 900 t-level bridge erecting machine,and analyzes the impact of the excitation frequency to the support structure,providing a reference for the mechanism selection and correction of motion parameters.
