摘要
树脂混凝土一般具有较好的力学性能,优秀的热稳定性和优异的吸振性,为了探究树脂混凝土的热稳定性,充分利用虚拟仿真技术和Pro/E与ANSYS Workbench协同仿真方案,建立了某超精密加工中心床身的实体模型。通过对树脂混凝土材质以及传统铸铁材质的床身热变形结果的分析,找到了影响机床床身热变形的主要因素,并对机床材料和约束进行优化。结果证明优化后的机床床身具有很好的热稳定性,为提高超精密加工中心的热稳定性能提供有用的理论依据。
Resin concrete generally has good mechanical properties, excellent thermal stability and great vibration resistance. The model of the ultra-precision machining center bed was established in order to study the thermal stability of the resin concrete by fully using virtual reality and collaborative simulation scheme based on Pro/E and ANSYS Workbench. The main factors that affected the thermal deformation of machine tool bed were found through analyzing the thermal deformation results of traditional cast iron material and resin concrete. Moreover the materials of machine tool and restrain conditions were optimized. The results prove that the optimized machine tool bed has good thermal stability, and theoretical basis is provided to improve the thermal stability of the ultra-precision ma- chining centers.
