摘要
针对500m高的施工升降机结构系统,建立有限元模型,对吊笼运行在不同位置时导轨架结构系统的模态进行了分析,又计算了采用不同附着间距下结构系统的固有频率,分析影响结构系统动态特性的因素,得到容易产生共振的运行速度区域,并总结了结构系统变形特点。
For the 500 meters the builder's hoist structure, building the finite element model and doing the modal analysis of mast structure with the cage's different positions, calculating the natural frequency for the structure with the different installation spacing, analyzing the factors which influenced on the dynamic characteristics of the structure.Obtaining the speed of regional which can cause the resonance and summarizing the deformation characteristics of the structure.
