压带式输送机压陷阻力有限元分析OA

As a kind of belt conveyor,the pressure belt conveyor has a compact structure and can realize large inclination transportation in a short distance.At present,domestic studies on the belt conveyor are relatively scarce,so it is necessary to analyze and study the two belts of the belt conveyor in order to figure out the influence law of different idler diameters on the subsidence resistance of the conveyor belts under the constant compaction force,which will further improve the design and calculation of the conveyor,continuously improve the operating efficiency of the conveyor and reduce the operating cost.In this paper,the main lifting section of belt conveyor with a bandwidth of 1 000 mm is taken as the research object,and the finite element analysis was carried out through the finite element model of conveyor belt and idler,and the contact stress of conveyor belt under different idler diameters was simulated.The simulation results show that the maximum stress of the conveyor belt appears at the contact with the idler.With the increase of the diameter of the idler,the contact stress of the conveyor belt increases,and the subsidence resistance decreases continuously.
