为了减小自移式掘进支护设备顶梁的质量,以增加设备自行移动的灵活性,降低工程造价,研究了基于大型有限元分析软件ANSYS Workbench的优化设计.首先用三维建模软件Pro/ENGINEER对自移式掘进支护设备的顶梁进行了三维参数化建模,定义了设计变量.在此培础上利用ANSYSWorkbench对顶梁进行了优化设计,以最大综合应力和整体位移为约束条件,以结构质量为目标变量进行优化改计.实现了顶梁结构11%的质量优化.对该类结构优化的难点问题提出有针对性的解决方法.为同类问题的解决提供了参考依批.最后对优化结果进行仿真分析,证明了优化方法的可行性.
In order to reduce the quality of roof beam of self-moving roadheader and support equipment and increase the flexibility of self-moving equipment and reduce the construction cost, the optimization design based on ANSYS Workbench is studied.Firstly, using 3D modeling software Pro / ENGINEER three-dimensional parametric modeling of the roof beam of self-moving tunneling support equipment, defining the design variables.On the basis of ANSYS Workbench, the roof beam was optimized design, the maximum integrated stress and the overall displacement constraints , And the structural quality is taken as the target variable to optimize the redesign, which realizes 11% of the top beam structure quality optimization.It puts forward some solutions to the problems of the optimization of this kind of structure, which provides a reference for solving the similar problems. Finally, the simulation results show that the optimization method is feasible.
