摘要
在架设大型桥梁时,可使用梁底轨道悬挂式运梁设备。本文根据使用要求,首先设计出梁底悬挂运梁设备中悬挂装置的机械结构,由悬挂梁、行走轮组和长销轴组成。通过Solidworks软件对悬挂装置进行三维实体建模,然后使用ANSYS Workbench软件中的静态结构进行有限元分析。通过静力学分析,得到模型整体变形和等效应力结果,其变形量满足使用要求,但存在4处应力风险区域。根据应力分布云图,对悬挂装置中的悬挂梁的结构进行了优化改进,改进后应力分布更加均匀,整个装置的最大变形量和最大应力皆减小,最大变形量为0.63 mm,最大应力为162.6 Mpa,同时悬挂梁的质量减小。整体达到了优化设计的目的,有助于悬挂装置的进一步设计与优化。
When erecting a large bridge, the beam bottom track suspension beam transportation equipment can be used. According to the application requirements, firstly, the mechanical mechanism of the suspension device in the beam bottom suspension and transportation equipment is designed, which is composed of suspension beam, walking wheel group and long pin shaft. The three-dimensional solid modeling of the suspension device is carried out through SolidWorks software, and then the static structure in ANSYS Workbench software is used for finite element analysis. Through static analysis, the overall deformation and equivalent stress results of the model are obtained. The deformation meets the application requirements, but there are four stress risk areas. According to the stress distribution nephogram, the structure of the suspension beam in the suspension device is optimized and improved. After the improvement, the stress distribution is more uniform,the maximum deformation and maximum equivalent stress of the whole device are reduced, the maximum deformation is 0.63mm, the maximum stress is 162.6mpa, and the mass of the suspension beam is reduced. The purpose of optimization design is achieved as a whole, which is helpful to the further design and optimization of the suspension device.
