摘要
介绍了三维振动台的结构原理和变刚度调谐原理,研制了变刚度试验装置,并研究了共振在变刚度系统中能量和振幅变化情况。实验表明在共振状态下能耗较低;在能耗降低一半的情况下,振动强度反而比非共振状态大10倍以上。经过发动机叶片在共振状态下进行强化抛光处理,表面粗糙度和疲劳强度都得到了大幅度改善,且减少了加工时间,降低了能耗。
The structural and tuning principle of three -dimension strengthening and polishing vibrating table are introduced. The variable stiffness testing equipment is developed, and the resonance variable conditions of energy and amplitude in variable stiffness system are studied. Experiment research shows that energy consumption relatively low under the resonance state. In case of reducing one half of the energy consumption, the vibration intensity in the state of resonating is more than 10 times higher than that in the state of non- resonating. Through strengthen polishing the engine blade, the surface roughness and fatigue intensity of the engine blade are improved largely under the state of resonating, and the processing time and energy consumption have been reduced.
