摘要
基于双缩尺比,将桅杆视为变截面梁,提出大尺度桅杆结构缩比试验中总体强度和振动的相似关系。应用PATRAN软件,对桅杆结构强度和振动进行数值仿真,通过桅杆原型和缩比模型的对比分析,验证相似关系的有效性。
Based on double ratio of reduced scale,treating the mast as s beam of non-uniform section,the similarity relation of total strength and vibration in reduced scale model test for large dimension mast structure is developed. The structure strength and vibration of the mast is calculated in PATRAN,so as to validate the similarity relation by comparing the calculating results and reduced scale model.
