【摘要】 利用ANSYS软件对烟气轮机动叶片进行模态分析,得到动叶片前6阶模态阵型图及叶片的固有频率,再利用谐响应分析,分析出动叶片在加工过程中发生强迫振动的频率范围,从而找到最佳铣削频率。在最佳铣削频率之上施加不同切削力,探求叶片加工位移量,找到加工叶片的最佳切削力。为叶片在加工中提高叶片加工质量提供理论指导。更多还原

【Abstract】 To carry on modal analysis of moving blade of flue gas wheel with ANSYS software, and obtain the first six order modal pattern of moving blade and its natural frequency, and analyze frequency range of forced vibration of moving blade during processing with harmonic response analysis, find the best milling frequency. Apply different cutting forces on optimal milling frequency, explore displacement of blade machining and find optimal cutting force, and provide theoretical guidance for improving machining quality of blades.更多还原
