Velocities and belt tensions are simulated for starting, running and stopping in a single computer run. Inclusion of static and inertial conditions for each mass of a distributed mass-elasticity mechanical model is used to assess possible design problems. Effects of profile, rolling resistance, drive inertia, take-up friction and dispersive wave action can be examined in advance of a final design.

Single-run dynamic simulation of conveyor belts

Conveyor belts are conducive to analysis using distributed mass-elasticity models. Numerous mechanically equivalent methods have been described in the literature over many years. In the work described here, each mass of a multi-element system is acted on by an acceleration that includes inertia, forces from adjacent spring-coupled masses and body forces due to gravity inclines, take-ups and rolling resistance. Once the acceleration of each mass is defined, element velocities and displacements can be accurately computed.
