摘要
针对带式输送机卸料小车车架变形大、易开裂的问题,利用有限元法对小车车架结构进行静力分析改进小车车架结构。采用CATIA软件建立车架三维模型,就ANSYS Workbench软件对65 t载荷工况下的小车车架进行静力分析,其最大应力为267.5 MPa,最大变形为17.46 mm,不满足强度和刚度要求。通过静力分析结果提出了车架结构改进的设计方案,将H型连接块更换为实体连接块,车架两侧梁之间焊接20 mm厚的钢板,并在钢板上加工一定尺寸的孔。最后对改进后的车架进行静力分析,其最大应力为123.7 MPa,最大变形为7.33 mm,满足强度和刚度要求。
In view of the large deformation and easy cracking of the unloading trolley frame of belt conveyor,the static analysis of the trolley frame structure is carried out by using the finite element method to improve the trolley frame structure.CATIA software is used to establish the three-dimensional model of the frame,and ANSYS Workbench software is used to analyze the static force of the trolley frame under 65 t load condition.The maximum stress is 267.5 MPa and the maximum deformation is 17.46 mm,which does not meet the requirements of strength and stiffness.Through the static analysis results,the design scheme for the improvement of the frame structure is put forward.The H-shaped connection block is replaced with a solid connection block.A 20 mm thick steel plate is welded between the beams on both sides of the frame,and holes of a certain size are machined on the steel plate.Finally,the static analysis of the improved frame is carried out.The maximum stress is 123.7 MPa and the maximum deformation is 7.33 mm,which meets the requirements of strength and stiffness.
