摘要:
 针对中药制丸机的螺旋输送器转子在复杂环境工作时,受到其他零件的振动干扰易发生低频耦合振动导致形变的问题,采用有限元方法对转子系统进行模态分析,建立了一种参数化关联模型,以转子导程、螺棱宽度和转子半径作为关联参数,通过响应曲面法对固有频率和形变量进行多目标优化分析,优化后的转子形变可降低至原模型的65%,频率提升13%。在约束条件内提高转子的固有频率可以有效的避免转子发生低频耦合振动,延长小型中药煎煮制丸机的使用寿命。
Abstract:
 Aiming at the optimization problem of the rotor of spiral conveyor structure of Pill making machine of Chinese Medicine when it worked in a complex environment easily lead to deformation which was caused by the low frequency coupling vibration from other parts′ vibration interference, using the finite element method for modal analysis. A parameterized association model was set up, spiral rib width and the rotor radius were refered as the correlated parameters.The response surface method was used to optimize the natural frequency and shape variables. The optimized rotor deformation can be reduced to 65% of the original model and the frequency is increased by 13%. Improving the natural frequency of the rotor under the constraint condition can effectively avoid the low frequency coupling vibration of the rotor, and extend the service life of the small Chinese medicine decocting and pelletizing machine.
