Thermal-mechanical coupling simulation calculation of trolley body of straight grate
In order to reveal the influence of temperature field and various loads on the deformation and stress of the main beam of the belt roaster trolley body under such cycle as low temperature-high temperature-low temperature,the body of a belt roaster trolley of a domestic iron and steel enterprise is taken as the research object.Both the ANSYS finite element analysis software and the direct thermal-mechanical coupling method are used to analyze the temperature distribution of the trolley body of the belt roaster in the drying section,preheating section,roasting section,soaking section,primary cooling section and secondary cooling section,while the deformation and stress of the trolley body in the roasting section under two working conditions of static action and thermodynamic coupling are calculated,and the influence of different beam height and roasting temperature on the stress and deformation of the trolley main beam is analyzed.The results show that the maximum temperature of the body in the roasting section is 650 ℃,the maximum temperature difference between the upper and lower surfaces is 140 ℃,the upper surface is compressive stress,the lower surface is tensile stress,the maximum stress is located in the middle of the main beam,which is 21.6 MPa,and the maximum vertical deformation is 5.37 mm.The influence relationship between different beam heights and roasting temperature on the stress and deformation of the main beam of the trolley is obtained through simulation calculation,which can provide a basis for the optimal design of the trolley body of the belt roaster.
