基于APDL的大载重集装箱参数化建模与分析

Parametric Modeling and Analysis of Heavy-Duty Containers Based on APDL

以某箱厂的大载重集装箱为研究对象,运用有限元软件ANSYS的二次开发工具(APDL),实现了用命令流的方式建立大载重集装箱参数化模型。通过采用APDL智能化分析方法,可以通过修改特征参数来建立不同形状、尺寸和属性的三维模型,减少了设计人员的反复建模,提高了工作效率。结合实验台,检测在多种工况下大载重集装箱的位移和应力,试验结果表明:各种工况下的位移和应力均符合船检合格标准,使其满足刚度要求,缩短了设计周期。

With heavy-duty containers of a container factory as the research object, a parametric model of heavy-duty containers has thus been established by using the secondary development tool(APDL) of ANSYS of the finite element software ANSYS. By using APDL intelligent analysis method, three-dimensional models of different shapes, sizes and attributes can be established by modifying feature parameters, which reduces the repeated modeling of designers and improves work efficiency. Combined with the test bench, a measurement can be achieved of the displacement and stress of heavy-duty containers under various working conditions. The experimental results show that the displacements and stresses under various working conditions meet the qualified standards of ship inspection, up to the stiffness requirement which helps to shorten the design cycle.
