Abstract:
The research on the causes and characteristics of belt deviation in the belt storage units of a telescopic belt conveyors is of significant importance for designing corresponding correction systems to enhance the operational stability and lifespan of the conveyor. This paper analyzes the normal, tangential, and lateral contact forces and restoring forces between the conveyor belt, pulleys, and idlers. Using a multi-body dynamics (MBD) method, a lateral MBD model of the multi-layer, multi-directional conveyor belt in the belt storage units is established, and simulation analyses are conducted to investigate its deviation characteristics. The results indicate that when the conveyor belt approaches or passes over a pulley with a deflection angle, it exhibits deviation movement. When the take-up pulleys have an in-plane and out-of-plane deflection angle, the maximum deviation of the conveyor belt occurs at the take-up pulley 3 and take-up pulley 2, respectively. Furthermore, the deviation of the conveyor belt is positively correlated with the deflection angle and the center distance of the pulleys. After deviating, when the conveyor belt passes through a take-up pulley or idler with an in-plane deflection angle, a resetting phenomenon occurs, thereby reducing the amount of deviation.
