【摘要】：对某型号刮板输送机的中部槽-刮板模型进行合理简化,结合仿生学非光滑形貌设计理论,利用UG建立了中部槽-刮板原试样、中部槽-凹坑型刮板试样、带凹坑型中板的中部槽-刮板试样的三维实体模型。基于ANSYS软件Surface-Surface自动接触算法,完成了3种试样中刮板与中部槽中板的摩擦接触分析,并对中板表面的接触应力进行对比研究。研究发现:通过对刮板或中板进行仿生凹坑设计,减小了中板表面接触应力的平均值和标准差,改善了中板表面的受力条件,进而减小了中板的疲劳磨损;同时,对刮板或中板进行凹坑型仿生优化还可以减小中板的磨粒磨损、冲击磨损、粘着磨损、热疲劳和热磨损;凹坑型中板的仿生优化效果明显优于凹坑型刮板。
[Abstract]:The model of a certain type of scraper conveyor is reasonably simplified. Combining with the theory of bionic non-smooth shape design, the original specimen of middle slot and scraper and the specimen of middle groove and pit type scraper are established by UG. Based on the ANSYS software Surface-Surface automatic contact algorithm, the friction contact analysis between the scraping plate and the middle slot plate in three kinds of specimens is completed. The results show that the average value and standard deviation of the contact stress on the surface of the middle plate are reduced by the bionic pit design of the scraper or the middle plate, and the stress condition of the surface of the plate is improved. At the same time, the particle wear, impact wear, adhesion wear, thermal fatigue and thermal wear of medium plate can be reduced. The bionic optimization effect of the concave plate is better than that of the concave scraper.
