采用实体单元建立了卧式螺旋卸料沉降离心机螺旋输送器的三维有限元模型,模型不但较好地模拟了螺旋输送器的真实结构,而且可以用来对螺旋输送器进行结构优化;静力分析结果表明,螺旋输送器在正常工况下的强度和刚度均满足要求;通过模态分析,取得了螺旋输送器前5阶固有频率,结果表明螺旋输送器在正常转速范围内不会发生共振现象。
The three-dimensional finite element model of horizontal screw discharge sedimentation centrifuge screw conveyor was established by using the solid element model. The model not only simulated the real structure of the screw conveyor well, but also could be used to optimize the screw conveyor structure. The results show that the strength and stiffness of the screw conveyor meet the requirements under normal operating conditions. By the modal analysis, the first five natural frequencies of the screw conveyor are obtained. The results show that the screw conveyor will not resonate within the normal speed range phenomenon.
