Simulation model for the verification of a safety-related control system in a hoist application
2018
Logistics Journal : Proceedings, Vol. 2018, Iss. 01 - Development of safety-related control systems requires extensive testing to verify correct functionality of the developed system in all circumstances. In this work, a simulation model of a novel hoist concept is shown. The simulation model consists of a complete electromechanical model of the drivetrain, including the pole-changing induction motor, slipping clutch and the brake, coupled with a two-mass spring-damped model of the hoist, the load and the crane bridge. The simulation model enables model-assisted testing of a hoist supervision unit currently being developed as part of a research project. We discuss the taken approach to software testing using the developed model.
