考虑桅杆缩尺模型制作需要兼顾几何高度和板厚两个因素，采用双缩尺比对桅杆缩尺模型进行设计，根据桅杆的相似理论推导了双缩尺比的可行性，基于patran软件建立桅杆原型和缩尺模型的有限元模型进行仿真计算，对比二者的模态频率、振型和振动规律，结果基本符合相似理论的推论，验证了基于双缩尺比桅杆模型设计的科学性与可行性。

The scaled model was designed based on double scale considering that the construction refers to geometric height and thickness .The feasibility of double scale was deduced according to the similar theory of mast .The FEM model of original mast and scaled mast was built for simulated calculation based on patran , the two models'vibration rule was gotten .Through com-paring its modal frequency and vibration type which is basicly consistent with the conclusions of similar theory ,so the design of mast model based on double scale proves to be scientific and feasible .
