摘　　要：采用有限元分析工具论述了大型复杂工程结构有限元参数化建模和不同零件之间边界问题处理方法,分析了高速数控龙门铣床静、动力条件下的结构性能与力学行为,研究了激振力频率对加工精度的影响,以及切削力、启动及停止短时间内的惯性冲击力引起的机床瞬态振动。The structure of large and complex project parameters of the finite element modeling and different parts of the border between the treatment of the issue are particular discussed with finite element analysis tool,high-speed CNC milling machine static and dynamic conditions of the structure and mechanical properties are investigated.Research on the frequency of vibration of the impact of precision machining,on the cutting force,launched to stop a short period of time and inertia from the impact of the transient vibration machine tools were studied.

关 键 词：动力特性方程 频率 瞬态振动 临界转速
