摘　　要：为探索提高机床基础件静、动态性能和轻质性的新方法,首先,以某加工中心框架组件为原型,初步设计玄武岩纤维树脂混凝土(Blasalt Fiber Reinforced Concrete,BFPC)龙门框架组件,分析典型工况下该框架组件的受力情况,并对原型龙门框架组件的静态、模态和谐响应进行仿真分析和计算。然后,对BFPC龙门框架组件进行拓扑优化设计,根据拓扑优化设计结果和BFPC龙门框架组件的制造工艺性,重构BFPC龙门框架组件结构。最后,对优化后的BFPC龙门框架组件的静、动态性能和轻质性进行仿真分析和计算,再与原型的相应性能进行对比分析。结果表明,拓扑优化设计后的BFPC龙门框架组件在静、动态性能和轻质性方面都明显优于原型龙门框架组件。In order to find a new way to improve the static performance,dynamic performance and lightness of basic parts in machine tool,we took the framework components of a machining center as a prototype to design the gantry framework components of basalt fiber reinforced concrete(BFPC).And then,we analyzed the force of framework components under typical working conditions.Moreover,the static,modal and harmonic response of prototype gantry frame were simulated and calculated.After that,we designed the topology optimization of BFPC gantry framework components.According to the results of topology optimization and manufacturing process of BFPC gantry framework components,we reconstructed BFPC gantry framework structure.Finally,the static performance,dynamic performance and lightness of the optimized BFPC gantry framework components were simulated and calculated.Meanwhile,we compared them with the corresponding performances of prototype.Simulation result show that the BFPC gantry framework components after topology optimization are obviously better than the prototype gantry framework components in static performance,dynamic performance and lightness.
