某拖曳水池重型拖车系统设计
|
摘要
针对拖曳水池重型拖车系统设计展开验证说明的问题,提出了一种应用于国家某重点专项大型拖曳水池的重型拖车结构,介绍了重型拖车系统基本组成,阐述了进行拖曳试验的工作原理。通过运用三维设计软件CREO2.0,建立了基于参数设计的重型拖车三维实体模型。基于建立的三维实体模型,采用有限元前处理软件Hyper Mesh及数值分析软件Abaqus对重型拖车车体及两型中央测试平台升降杆的静刚度及强度、固有频率等展开了仿真分析,在此基础上对影响重型拖车运行精度的轨道系统进行了强度、挠度及固有频率的分析计算。研究结果表明:该型重型拖车的整体结构强度及固有频率等指标均能满足设计要求。
In order to verify the design of heavy trailer of towing tank,a heavy trailer structure was presented. The basic components were introduced,and the working principle of towing test of the trailer system was expounded emphatically. Using the 3D design software CREO2. 0,the model of the trailer was built based on the parameter design. Based on the solid model,the finite element analysis software Hyper Mesh and Abaqus were used to simulate the static stiffness and strength and the natural frequency of the trailer and the central bridge lifting rod.On the basis of this,the correlation analysis and calculation of the track system which affected the precision of the trailer was carried out.The research results show that the structure strength and natural frequency of the trailer can meet the design requirements.
