Conveyor Simulation

 · I''m using setTargetVelocity on static objects to simulate conveyors. When the box rides along one conveyor and then slides onto a second conveyor running at a higher speed the transfer doesn''t work quite right. The box''s velocity stays at the slower speed (matching the first conveyor''s target) until the box has completely cleared that conveyor. Once it is no longer …

Control Conveyor Belt Acceleration

2020-11-7 · Control Conveyor Belt Acceleration. The part that acceleration plays in starting a belt conveyor and its effect on belt conveyor design are well understood in a general way. Its practical importance is easily overlooked, however, and under some conditions, it is absolutely necessary to give the problem of acceleration detailed study.

1175: Moving Sidewalks
