【摘要】：目前带式输送机被广泛的应用于各个生产生活领域。但由于各种因素经常会引起输送带的断裂,导致断带事故的发生,造成严重的财产损失和人员的伤亡。因此为了降低断带事故发生后造成的损失,需要不断的开发研究新的断带保护装置。本文对阻尼板的结构进行改进,确定阻尼板的垂直安装位置,分析断带后输送带的运行情况并对槽形阻尼板断带防滑的可行性进行研究。设计中考虑到输送带有一定的刚度,因而将输送带作为复杂梁进行处理研究,建立其力学模型。通过分析得出阻尼板的长度、宽度、厚度和槽形角。对阻尼板的强度进行验证,从而确定阻尼板的结构。利用UG软件建立带式输送机的三维模型,通过数据接口把模型导入ANSYS Workbench软件,进行工作载荷下的有限元分析。对比有限元分析的结果得出影响输送带垂度的因素,为确定阻尼板的垂直安装位置提供理论依据。分析Maxwell、Kelvin、三元件固体粘弹性模型的优缺点,确立输送带的粘弹性模型。根据带的粘弹性模型建立带式输送机整机的动力学模型。利用Matlab软件进行断带过程的仿真,分析输送带的运行过程,为阻尼板防滑的可行性研究做准备。计算确立阻尼板的最优安装数目,运用RecurDyn软件进行动力学仿真分析。对比不同工况下槽形阻尼板的断带保护效果,确定槽形阻尼板防滑的可行性。本文为以后阻尼板的研究提供了理论基础和设计方法。为以后阻尼板的进一步改进和研究提供了参考。
[Abstract]:At present, the belt conveyor is widely used in every field of production and life. But because of various factors, it often causes the fracture of the conveyor belt, causing the occurrence of broken belt accidents, causing serious property loss and casualties. Therefore, in order to reduce the loss caused by the broken belt accident, it is necessary to develop and study the new belt protection suit constantly. In this paper, the structure of the damping plate is improved, the vertical installation position of the damping plate is determined, the operation situation of the conveyer belt after the broken belt is analyzed and the feasibility of the anti slip of the slot type damping plate is studied. In the design, the conveyer belt is considered as a complex beam, and the mechanical model is established. Through the analysis of the length, width, thickness and groove angle of the damping plate, the strength of the damping plate is verified, and the structure of the damping plate is determined. The three-dimensional model of the belt conveyor is established by UG software. The model is introduced into the ANSYS Workbench software through the data interface, and the finite element analysis under the working load is carried out. The result is the factors that influence the sag of the conveyer belt to provide a theoretical basis for determining the vertical installation position of the damping plate. The advantages and disadvantages of the Maxwell, Kelvin, three element solid viscoelastic model are analyzed, and the viscoelastic model of the conveyor belt is established. The dynamic model of the whole belt conveyor is established according to the viscoelastic model of the belt. The Matlab software is used to break the model. With the simulation of the process, the operation process of the conveyor belt is analyzed, and the feasibility study of the damping plate is prepared. The optimum installation number of the damping plate is calculated, and the dynamic simulation analysis is carried out by RecurDyn software. The protective effect of the slot type damping plate under different working conditions is compared, and the feasibility of the anti slip of the slot type damping plate is determined. The study of post damping plate provides a theoretical basis and design method, which provides a reference for further improvement and research of damping plates.
