基于ICM拓扑优化的加工中心床身轻量化设计

摘要

为实现高速卧式加工中心床身的轻量化设计，以床身的质量最小化为目标，提出了基于ICM方法的拓扑优化模型。分别对床身进行了二维、三维拓扑轻量化设计，并对设计结果进行了可制造化处理，给出了床身优化后的仿真模型。基于有限元理论对新床身进行静动态性能分析。结果表明，在新床身具有良好的静动态性能的前提下，新床身比原床身质量减少了13％，实现了加工中心床身的轻量化设计。%In order to realize weight-reduction design of high-speed horizontal machining center bed,topological optimization model based on ICM method was proposed with a view to minimize the mass of the bed. The 2D and 3D topology weight-reduction de-sign for the bed were respectively given,and manufacturability process for the design results and the simulation model of the bed after optimization were given. Static and dynamic performance analyses for the new bed were given based on finite element method (FEM). The results show that the weight of the new bed reduces 13% than the old bed in premises of the new bed with good static and dynamic performance,which can realize the weight-reduction design of the machining center bed.
