采用SolidWorks三维建模软件,对SLO2496型振动筛建立了实体模型,将模型导入到ANSYS Workbench软件中,对其进行模态分析及谐响应分析,计算出了前12阶固有频率、模态振型及工作频率下的动应力响应,找出了离工作频率最近的固有频率下的振型,以及额定载荷下整体的动应力分布情况和动应力集中的部位。提出了结构优化方案,对振动筛局部进行了改进。通过对比分析,改进后的振动筛工作频率远离了固有频率,动应力集中的情况也得到了改善。
SolidWorks 3D modeling software was used to establish a solid model of SLO2496 shale shaker. The model was imported into ANSYS Workbench software. Modal analysis and harmonic response analysis were carried out. The first 12 natural frequencies, mode shapes And the dynamic stress response at working frequency, find the vibration mode at the natural frequency closest to the working frequency, and the overall dynamic stress distribution and dynamic stress concentration under the rated load. Proposed structure optimization program, shaker part of the improvement. Through comparative analysis, the improved working frequency of vibrating screen is far from the natural frequency, and the dynamic stress concentration is also improved.
