摘要
作为农田水利运输时重要的部件,渠道的强度达标是渠道正常工作的最重要标准。通过高密度聚乙烯(HDPE)力学性能试验测试了材料的基本力学性能,完成基于ANSYS Workbench的组合式HDPE渠道强度仿真,并进行了强度对比分析渠道安全可行性。首先通过力学试验得出使用HDPE材料的基本力学性能,然后运用Solid Works三维设计软件构造组合式单个渠道三维实体模型并导入ANSYS Workbench软件中,设计渠道网格划分和边界条件及载荷约束后进行仿真分析计算,得到单个渠道预制构件应力大小分布情况,导出渠道等效应力和最大应力云图,定位单个渠道构件最易破坏位置,将仿真结果与实测强度进行对比分析,得出分析结果,验证结构受力分析的正确性。
As an important part of farmland water conservancy transportation,it is the most important standard for the normal operation of the channel that the strength of the channel meet the requirement.The basic mechanical properties of the material were tested through the mechanical properties test of high-density polyethylene(HDPE),and the strength simulation of the combined HDPE channel based on ANSYS Workbench was completed,and the strength comparison and analysis of the channel safety feasibility were carried out.Firstly,the basic mechanical properties of HDPE materials are obtained through mechanical tests,and then the 3D solid model of a combined single channel is constructed using Solid Works 3D design software and imported into the ANSYS Workbench software.After the channel grid division,boundary conditions and load constraints are designed,the simulation analysis and calculation are carried out to obtain the stress distribution of the prefabricated components of a single channel,and the equivalent stress and maximum stress nephogram of the channel are derived,The most vulnerable position of a single channel component are located,by the simulation results and the measured strength are compared and analyzed,and the analysis results are obtained to verify the correctness of the structural stress analysis.
