为了获取矿用振动离心机的工作情况,运用数值仿真软件对卧式振动离心机的关键部件进行了有限元分析,仿真分析得到离心机关键部件的应力、应变、位移随工作状态的变化情况,并对其模态进行了相关的分析。结果表明:初次振动时,应力主要集中在机壳的两侧;当振动频率达到22.976 Hz时,振动离心机达到稳定的运行状态,此时与振动电机固有频率相接近。通过对振动离心机的振动及模态分析可为振动离心机的设计提供一定的参考。
In order to obtain the working condition of the mining vibration centrifuge, the finite element analysis of the key components of the horizontal vibration centrifuge is carried out by using the numerical simulation software. The stress, strain and displacement of the key components of the centrifuge are obtained through the simulation analysis. And the related modal analysis. The results show that the stress mainly concentrates on both sides of the housing during the initial vibration. When the vibration frequency reaches 22.976 Hz, the vibration centrifuge reaches a stable operating condition, which is close to the natural frequency of the vibration motor. Vibration centrifuge vibration and modal analysis can provide some reference for the design of vibration centrifuge.
