| 摘 要： | 为解决卧式振动离心机处理能力小、噪声大、能耗高的问题,在理论计算模型指导有限元建模和简化参数基础上建立双质体卧式振动离心机三维模型,并对其进行模态分析和谐响应分析。结果表明:激振频率f在25～27 Hz时,双质体卧式振动离心机工作状态最佳;当激振频率f=26 Hz时,初级振动质体和二级振动质体振幅最接近理想状态,且此频率是设备最佳工作频率;弹簧刚度比ρ≥5时双质体卧式振动离心机相对较稳定。 |

Research on performance optimization of double-mass horizontal vibrating centrifuge |

| Abstract: | In order to solve the problems of low processing capacity,high noise level and high energy consumption of the horizontal vibrating centrifuge.Based on theoretical arithmetic,finite element modeling and reduced parameter,established three-dimensional model of double-mass horizontal vibrating centrifuge,and on which carried out modal analysis and harmonic response analysis.The results show that when the excited frequency in the range of 25~27 Hz,the centrifuge worded best;when excited frequency= 26 Hz,the amplitudes of primary mass and second mass are all closed to the ideal state and with the best vibration frequency;when spring stiffness design reference ρ≥5 the centrifuge worked stable. |
| Keywords: | double-mass vibrating system horizontal vibrating centrifuge modal analysis three-dimensional model harmonic response spring stiffness |
