【摘要】：介绍了Hypermesh软件与CAD软件联合仿真的步骤,重点阐述了该建模方法中对网格的形状、疏密和衔接进行控制的原则。以不均匀地基上结构复杂的某水闸为例,系统地介绍选取特征断面构造模型几何轮廓、综合考虑多个断面划分二维网格和借助土层分界面建立地基的建模方法。经检验,该水闸模型质量满足仿真要求,计算结果符合水闸受力特征,最大拉应力为3.077 MPa(顺河向),出现在闸门过水1工况下水闸边墩支座上。Hypermesh结合CAD平面图建模的方法能够实现复杂水工结构仿真,对水工结构的安全评估具有一定参考价值。
[Abstract]:This paper introduces the steps of joint simulation of Hypermesh software and CAD software, and focuses on the principle of controlling the shape, density and connection of grid in this modeling method. Taking a sluice with complex structure on uneven foundation as an example, this paper systematically introduces the modeling method of selecting characteristic section to construct model geometry, comprehensively considering the division of two-dimensional grid of multiple sections and establishing foundation with the help of soil interface. The results show that the quality of the sluice model meets the simulation requirements, and the calculated results meet the stress characteristics of the sluice. The maximum tensile stress is 3.077 MPa (along the river direction). HyperMesh combined with CAD plane diagram modeling method can realize the simulation of complex hydraulic structure, which has certain reference value for the safety evaluation of hydraulic structure.
